INTRODUCTION
About Me
Chew Yi Tian, Chloe
I was born and raised in a vibrant cosmopolitan
city, Singapore. I moved to Melbourne in February 2015 in pursuit of my Architecture degree in University of Melbourne. People often ask me, “Why Architecture?�. I got to admit that it all started with a computer game called The Sims. I was introduced to it at the age of 8 and was hooked onto Architecture ever since. Growing up determined to be an architect, I eventually graduated from Singapore Polytechnic with a Diploma in Architecture.

Throughout my three years in school and a year of working in architectural firm, I have gained an amount of knowledge in digital design and was able to equip myself with various digital softwares like Revit, Google SketchUp, Adobe Photoshop and Illustrator. Parametric modeling is new to me, as I have no prior knowledge in Rhino and Grasshopper. However having said that, I am very eager to explore the endless possibilities of this digital designing software.
INTRODUCTION
Previous Work
I was first taught AutoCAD and 3D Max during
my first year of diploma. It helped me better visualize my design concepts and assisted me through my design processes. However, I do feel restricted at times due to the limitation of the design softwares. We were also introduced to 3 dimensional modeling program such as Google Sketch Up and I later self-taught myself Autodesk Revit through online video tutorials.
During the 2nd year of my polytechnic, we were tasked to design a 10 storey residential apartment for a group of Yuppies. My design was focused around the concept of embracing nature into the building by incorporating existing site natural elements (eg. framing of views). I used the Building Information Modeling (BIM) program, Revit, throughout the project. It helped save time and allowed me to better understand my project.

As the demand for steel increases globally,
the designers decided to utilize parametric design to cut waste while creating functionality and form. This allows design changes to be made with minimal effort while the design team efficiently explore design alternatives and variations with the conceptual constraints. To design the exterior, an integrated parametric system was created to conceptualize, simulate, and document the complex geometric systems. Parametric control of the point cloud was the primary means of controlling the form. Parameters for manipulating the point cloud enabled the design team to study different configurations of the exterior surfaces (Fig. 2). For conceptualization, the parametric system was set up to explicitly define the control surface geometry and study formal variations. Physics simulation tools were used to test basic structural behavior. For detailed analysis and engineering,
custom scripts were used to automate the communication of centerline information to the structural engineering team. As for documentation process, parametric workflow systems were invented to link together disparate design and documentation environments for a more seamless international collaboration. The rapid acceleration towards global practice coupled with advancements in informationbased economies necessitate that architects develop their systems and processes to be adaptive and flexible. This project with similar areanas like the famed Bird’s Nest, the Beijing National Stadium, was completed in year 2013. It strongly exhibited the process where new design tools were invented, developed, integrated, coordinated, modified and shared for the purposes of delivering a project of a spcial civic value in China. 9

to’s design strives for architecture that is fluid and not confined by the limitations of modern architecture. He experimented with the light aluminum material and incorporated a certain degree of transparency. At first look, the building appeared to be a complicated mixture of random pattern. However, it is in fact derived from an algorithm of a cube that expanded as it rotated (Fig. 5). The use of parametric designing is largely evident in the design of the façade. The intersecting lines created by the rotation formed different triangles and trapezoids that gave a sense of infinite motion. The placement of materials were designed to maximize framing of the surrounding environment (Fig. 4).
The creation of the pavilion sparked several encouraging and positive thoughts when it opened, comparisons were made to other new buildings and the gallery came out on top. The pavilion also sparked peoples interest in parametric designing when it came out in 2002, it was one of the buildings that clearly demonstrated the use of algorithm for architecture. It was an eye opener for other architects to learn what parametric design was all about. It was a bold move by Ito that was well received to the public. Even though the building was only up for 3 months, it has been regarded as one of the most successful temporary pavilions till date. 11

A.2: DESIGN COMPUTATION
Design Computation
Formal meaning of digital design was to
computerize ideas that were preconceived in the mind of the designer. While it is often referred to as digitized design or computerization, it no longer is seen as a truly creative digital practice. The use of digital in Architecture has moved from being a documentation tool to a much more powerful computational tool. With that, designers are now able to extend their abilities to deal with highly complex situations as it allows the exploration of new ideas. The processing of information and relationship of elements which constitute to a specific environment; providing a framework for negotiation and influencing the interrelation of datasets of information, with the capacity to generate complex order, form and structure3 which can be expressed as an algorithm. Computational design advocates a total new approach to the design process where algorithmic programming for a set of outlines and variables are done which it then computes and derive the formal composition. Through this approach, designers are able to simulate building performance by incorporating performance analysis and knowledge about material, tectonics
and parameters of production machinery in their design drawings. This methods employs the faultless and thorough manner of the computer to run monotonous data and processing, which is something that the human mind lacks of. This takes over an interpretive role by understanding the results from generating code, and through modification, new option and design with further potential is being created. Computation design impact the fabrication and construction of the building greatly as it currently tends to be the development of parametric families of components and in necessary control of the data. Computation presents an integrated design approach which allows further flexibility towards the later stages of a design project as parameters can be tweaked without the need to redesign the entire work. In the early stage of this approach, conceptualization and criteria designing & detailing will be resolved so that the final built form can be computed in a relatively short period of time. This allow increase efficiency and allow for better communication.

The whole planning uses an intelligent
environmental infrastructure, allowing endangered plants, which could not normally be found in Singapore to flourish, this provide both leisure and education purposes for the inhabitants.4 By engaging with contemporary computational design techniques and parametric studies, it allows creation of the dome to open up all possibilities and the flexibilities of forms and materials. The envelope itself consists of a grid shell-arch steel structure with a double glazed skin that sits directly on the grid shell, and the arches are the main load-bearing components. Supertree was created with the purpose of sustainable energy and water technologies integral to help cool the space. (Fig. 8) With the intend for the display of the plants that typically
thrive separately in cool dry and cool moist climates, careful planning and calculation was being done to ensure sustainability is acheived. With the help of parametric modelling and engineering, it brought about the realization of column-less, magnificent space. (Fig. 9)

hellstar is a lightweight temporary pavilion that maximizes its spatial performance while minimizing structure and material. The form emerged out of a digital form-finding process based on the classic techniques developed by Antonio Guadi and Frei Otto, among others. Using Grasshopper and the physics engine Kangaroo, the form self-organizes into the catenary-like thrust surfaces that are aligned with the structural vectors and allow for minimal structural depths.5 The structure is composed of nearly 1500 individual cells that are slightly non-planar. In reality the cells must bend slightly to take on the global curvature of the form. However, the cells cannot be too non-planar as this would make it difficult to cut them from flat sheet materials.
Using a custom Python script, each cell is optimized so as to eliminate any interior seams and make them as planar as possible, greatly simplifying fabrication. Using more custom python scripts, each cell was unfolded flat and prepared for fabrication. The cell flanges and labels were automatically added and the cell orientation was analyzed and then rotated to align the flutes of the Coroplast material with the principal bending direction of the surface (Fig. 11).6 Using contemporary computational design techniques, the designers were able to achieve their goals in mind through the exploration of new ideas. The way that the arched structural forms congregate to dispersed point is also worthy of mention.

A.3: COMPUTATION/ GENERATION
Computation/ Generation
Opposing the conventional understanding
of form generation through drawings, generative design allows the exploration of new ideas which increases the designer’s ability to solve complex problems efficiently. By providing a framework of information through an understood language of algorithm between the human and the design computation software, it is able to generate performance feedback at various stages of a project to help increase productivity. Computation invites a vast exploration space for computational concepts, such as topological geometries, isomorphic polysurfaces (“blobs�), motion kinematics and dynamics, key shape animation (metamorphosis, parametric design) etc.
This analytical computation can be used to actively shape the buildings into a more dynamic outlook. Though the shift from composition to generation created more room for innovation that cannot be generated through conventional design process, it on the other hand limit designers who have yet familiarize themselves with the design computation software that may result in less impressive end products and waste of time in the process. It also invite impractical imagination of designer. Computation should not be entirely relied on but it should be used to its fullest advantage as an accompanied tool for designers who will eventually be the moderator of the overall design.

During the analysis of different biological structures, the plate skeleton morphology of the sand dollar became a basic principles of the bionic structure.
Form finding and structural design are closely interlinked through computation programs8 and it optimized data exchange which made it possible to analyze and modify the critical points of the model. The modular system of polygonal plates are linked together at the edges by finger-like calcite protrusions and the glued and bolted joints were tested based on the structural calculations generated. 25

he project aim was to relate to that historical understanding of architecture by developing a firmly contemporary interpretation, reflecting a more nuanced understanding. Fluidity in architecture is not new to this region. In historical Islamic architecture, rows, grids, or sequences of columns flow to infinity like trees in a forest, establishing non-hierarchical space. The public plaza, as urban ground, undulates and folds upwards to create internal spaces, a whole new kind of inclusive public civic space for the city.
A design that was inspired by “the fluid geometry of water in motion� was developed using computation software, it is a highly precise but constantly evolving digital model. Advanced computing allowed for the continuous control and communication of these complexities among the numerous project participants.9 27

A.4-A.5: CONCLUSION AND LEARNING OUTCOMES
Conclusion & Learning Outcomes
Architecture is seen, experienced and
felt every second of our life, transcending both time and space. It has always been a method for cultures to express their influential movements. It is so much more than a structure or a built form. It reflects the economic, social and political cultures. We have shifted from digitalizing designs that were preconceived in the mind of the designer to computation where our designs will be further explored in ways that we can never do. In the past, Computer Aided Design softwares were meant for a more accurate and faster way of documentation and communication. However, architecture is moving towards parametric design and algorithmic sketching. It is innovative as it enables the creation of new geometries, the use of new structural systems and implementation of new construction technologies. A new design logic and a different way of thinking results in an architectural language and style that is unique and fresh, steering clear of conventional forms and designs. Personally, I believe that computational design has had a positive impact on Architecture. The outcomes that are proposed by this approach augment architectural intellect and unfold innovative discourse that cannot be predicted. In the next part of this journal I will be exploring and experimenting with algorithmic scripting and design in response to our given design brief.
It has been an eye-opener thus far. Studying of algorithmic design through learning Grasshopper (not forgetting the frustration of not getting it right), and studying of precedents, the logic of parametric design is something new and foreign to me. Before beginning this module, I am ashamed to say that I have never thought of the difference between computerization and computation methods that are now instilled in me. Parametric, generative design, algorithmic scripting, all these terms are defining a new architectural approach that is taking place. It is interesting to see how computation softwares have pushed the limits of design with project like Research Pavilion by ICD/ITKE. Unlike traditional lightweight construction which can only be applied to load optimized shapes, the new design principle derived through computation can be applied to a wide range of custom geometry. I have also learnt some new skills with regard to parametric modeling in Rhinoceros and Grasshopper. I believe that this studio is a learning curve and that I am simply at the beginning and it is an opportunity to discover new creative happenings.

was tasked to create an undulating ground surface and investigate biomimetic forms, using the box morph tool and propogate it over the surface. Although it was not a very successful take on the biomimetic form, I have manage to create a unique undulating form with the surface pattern of a geometry that I have created myself. This results in a very different end product than what I expected. These sketches demonstrate that tractability of parametric modelling. Numerous iterations can be derived from a single entity within a short time frame.
A box geometry that can be manipulated by voronoi 3d and by removing a few blocks, it creates an interesting form almost instantly.
The change can be visualized in real-time and in three-dimensions instantly. It is efficient in fabrication preparation and that is a huge advantage as it allows designers more time in the exploration stage that will not be compromised by physical and time constraints. Due to its nature, the parametric models also encourage the designers to discover the unexpected outcomes (e.g. by simply rotating the model or a wrong connection of components) that could result in something new. 33

Biomimicry
Fig. 19 : Biomimicry in Nature (Courtesy of Autodesk)
The nature is the largest laboratory that ever
existed and ever will. Biomimicry is providing an opportunity for digital design techniques to be implemented through the framework of ‘biologically inspired processes’.11 This new way of design process applies to principles governed by nature which are supported by billions of years of evidence. The design process is not simply the replication of form, but rather the investigation and adaptation of the system. Therefore, Biomimicry provides the opportunity to employ tools and ideas otherwise unavailable to the designer. This enables the application and imitation of nature’s design resolutions and ideas in an attempt to resolve human problems in the movement towards conditions conductive to life. Nature provides an opportunity to generate forms which consider and manipulate materiality enabling fabrication of forms which imitates a sustainable system as much of the complexity, strength, toughness and sophistication generated by nature are made of
Fig. 20 : Research Pavillion 2012 (Courtesy of IDC/ITKE)
simple materials (ie. Keratin, Calcium carbonate and silica).12 The philosophy of biomimicry is the borrowing of the ‘fundamental formative processes and information systems of nature in the search for solutions to the environmental and human problems which govern our designs.13 Through the understanding and appreciation of the complex structure of nature, we will then be able to explore the potential of this design technique. Computation has enabled this exploration and design technique to evolve and inform design through scientific explanation. As explored in earlier precedent projects, such as the Research Pavilion designed by IDC/ITKE exhibited the potential produced by biomimicry adaptive system in conjunction with computational methods. Nevertheless, intensive material research is required in order to incorporate material adaptability through the design process. 37

his installation, titled VoltaDom, was developed by SJEY, which was founded by Skylar Tibbits. It was created as an entry for the 150th FAST Arts Festival and as a result, it is currently situated on the MIT campus, spanning through a corridor.14 This design explores the use of computational processes, and this is evidenced through the development of a complex and highly geometric pavilion structure. In a sense, this design is reminiscent of the vaulted ceilings in ‘Gothic Architecture’, within the cathedrals in particular, as they play a part in enhancing acoustics. It was developed in conjunction with computer coding, and was later created using fabrication technologies. In my opinion, the white use of materials provides the structure a dynamic
quality as the geometry in conjunction with light adds a multi-faceted view, which in turn comes down to the intricacy and detailing of the extruding elements. This project explores the ideas associated with architectural “surface [paneling]”, which came into play through the assembling of this installation. Fabrication strips were used as a method of creating the curved vaults (as evidence through the area where the vaults intersect).15 In the pages that follow, I aim to explore the lengths of manipulation, by substituting the geometries for others as well as placement of points and its boundary.

Successful Iterations & Selection Criteria

Iteration 2.4
Iteration 3.2
Iteration 3.5
Iteration 4.5
B.2: CASE STUDY 01
GENERATIVE PROCESSES While generting the 6 series of different iterations, my aim was to understand the algorithm through flexing, the function of each node and figuring out which inputs could be replaced and still work with the other components. Through manipulating the numerical values, I begin to manipulate the nodes themselves. Therefore, there is no direction in terms of form. Through that I begin to experience “research by design” as mentioned by Rivka and Robert Oxman.
SELECTION CRITERIA My generative processes were lack of a formal direction from the start, however my generative criteria for the iterations were generated mainly around the potential of it as an architecture. Focusing more specifically on the dynamism, perforation, geometry and pattern. Although I ended up with some iterations that look different from the original purpose of the algorithm, I managed to create many new designs with the original geometry of the project.
HIGHLIGHTS ITERATION 2.4: Retaining the original geometry, I arranged them in a triangular grid manner which turned out to have a very interesting result. The form created negative and positive spaces which allows for perforations that has the potential as a wall cladding. ITERATION 3.2: The look of the geometry
changed drastically as I manipulated the numerical values of the cones and also arranged them in a radial grid manner in which the overlapping geometries generated a very interesting overall pattern. ITERATION 3.5: Instead of the origin points laid out in 2d, I decided to manipulate the points with a 3d generative component. The end result was very pleasing as it demostrated perforation within the form and with the geometries overlapping each other in different plane, it created depth which gives an idea of movement. ITERATION 4.5: I manipulated the numerical values of the cones opening to create a cylinder looking base geometry, and with the number of origin points increased it in turned increased the perforation of this form. Something to note is that in my iteration 5.3 it displayed a similar looking form, this shows that there is more than one way to manipulate the algorithm that will generate the similar end result.
SPECULATION Instead of looking at it as a wall cladding or panelling, each iterations could be seen as positive and negative space that will be extruded out as “rooms”. Perhaps the entire series of 1 could be further developed with that idea. Selected iterations such as 2.4 could also be further developed with the idea of secondary spaces surrounding a core area. Iteration 3.2 could also be looked at it the same way with the most important space in the “heart” of the form and less important spaces spreaded out to the peripheral area. Iteration 3.5, however, will not work and therefore becomes irrelevant. As for iteration 4.5, it can also work for the idea of positive and negative spaces. 43

ZA11 Pavillion is a project designed
and fabricated by a group of students in Cluj, Romania, with the use of advanced parametric design techniques. It has a strong representational power and is integrated into its historically-charged context. With a small budget and donated materials, the design brief was to create an innovative pavilion that could be flexible space for uses ranging from a temporary book shop to a performance space. The temporary space was designed to intrigue passersby and to draw them into the space for various events. This was achieved by creating a spectacular ring subdivided into deep hexagonal prisms that could both define the venue for the
events as well as provide glimpses to intrigue and attract people into it. This project succeed in reaching its goal as a powerful urban attractor which managed to engage the local society on all levels. Both young and senior citizens, both professionals and non-architects by the completed pavilion as well as during the act of its construction, thus this proves to be more than an indifferent temporary shelter.16 This integration allows a possibility to create vast amount of variations through changing geometry and patterns. 45

STEP 1: Basic shape of ZA11 Pavillion derived from 3 irregular shape of rings. Also a point in the centre of the rings was set, it will be used in the later steps. STEP 2: Lofted the curves to get the base surface. STEP 3: Applied irregular hexagon cells on the base surface using the Hexgonal cells component.
STEP 3
STEP 4: The base surface was copied, moved and scaled down by the centre point that generates the inner surface. STEP 5: Lofted the corresponding lines of hexagon on the inner and outer surfaces, which was then DeBrep-ed to obtain individual surfaces. The surfaces were then extruded and capped to give it a thickness. STEP 6: Applied the pattern created to each individual surfaces. The pattern was then scaled down to create a smaller triangle that was meant to be the â&#x20AC;&#x153;cut-outâ&#x20AC;?. To achieve the effect, the smaller triangle was extruded and solid trimmed with the extruded surfaces accordingly.

er Definition
Pattern was made by Rhinoceros and set by Grasshopper as a surface. The surface are divided diagonally to make a right-angled triangles. Two points are generated symmetrically by the diagonal and then by the points, scaled down and right-angled triangles are generated just like the way inner and outer shell of basic surfaces are formed. Then, trim two smaller triangles to make a hole. 51

CHALLENGES
DIFFERENCES
I was stuck for a couple of time befores deriving with the final definition that achieved the closest result to the chosen project. Challenges faced:
The differences between my reverse engineered model and the original project piece is the type of joinery that connects each individual piece together. Also, the hexagons generated in my reverse engineered model is more uniformly arranged whereas the one in ZA11 Pavilion is more randomly distributed throughout. Lastly, the inner surface was created by scale and move of the external surface in my reverse engineered model, however the original project may have used the process of extrusion of hexagon cells for a certain distance instead of scaling the external surface.
• Surfaces had no thickness to it. Resolved it by extruding and capping all the holes. • Initially at Step 6 where triangular holes are needed to cut out from the base form, SolidDifference component was used but it did not work. Resolved it by replacing the component with SolidTrim. • Baked and realized that the surfaces where the triangles were being trimmed off are not covered. Resolved it by brepping the scaled inner triangles.
SIMILARITIES The similarities between my reverse engineered model and the original project piece is the overall shape as well as the hexagonal cells on the surface. The pattern projected on each
CONCLUSION In conclusion, each individual pieces have to be in a correct order as generated by the design computational software in order for the whole structure to work. As each piece has a different shape and size, this design relies greatly on the parametric design technique to generate the results for fabrication. Without the constraint of the original form and some alterations, perhaps it could be used as a continous piece of multi-function landscape furniture. 53

ITERATIONS For the iterations on page 56 & 57, I mainly derived them from replacing the hexagon cell grid to varies options on a plugin for grasshopper called LunchBox. It is a useful tool as it allows me to explore the various types of structural grid. I further manipulated them by trying to achieve my design criteria by changing the form of the base curves that determines the overall form of my structure. Interestingly, the end results were satisfying as I manage to achieve structure with spatial qualities. For the iterations on this page, my aim was to go beyond the definitionâ&#x20AC;&#x2122;s limit. As shown in the first row of iterations I have replaced the extrude component with pipe component and the results I got were pleasant, some of them seem to be exploded off the structure itself. It is interesting to see how by just replacing a component can do such difference to the overall form. For the second row of iterations on this page, I tried out the components on weaverbird for a change. Retaining some of the original geometries selected from previous iterations, my aim was to change the pattern on each surface. However, I did encounter a few challenges before arriving at shown iterations. Intiailly I replaced the triangular pattern with a square but it did not work. Thus, after experimenting with a few others, I finally settled with using the components Constant Quad Subdivide & Panel Frame from LunchBox plugin under generate tab as seen on the last 3 rows of iterations.

GENERATIVE PROCESSES While generting the 50 different iterations, my aim was to slowly evolve away from the original definition until they are no longer identifiable and also pushing the definition to its limit. Besides manipulating the numerical values, I also begin to replace components for varying end product.
SELECTION CRITERIA Similar to my previous selection criteria, the iterations were generated mainly around the potential of it as an architecture. As I have a clearer idea of what my design proposal is going to be like, I generated the iterations around it. Focusing more specifically on being structurally biomimicry, geometry & pattern, perforation and also the spatial quality created. I would like to create varying openings that will contribute to the spatial quality and also guide the users towards CERES.
HIGHLIGHTS SUCCESSFUL ITERATION 1: For this iteration, I experimented with the perforation of each panels by manipulating the geometry and pattern. First, I changed the base geometry to (almost) the form I derived from my site analysis for the chosen site. With that, I changed the patterning of each panels with a Constant Quad subdivided component and the end result was very pleasing as it demonstrated a different perforation within the form. This will create a unique light and shadow play within the space. The amount of light passing through can be controlled with the U and V value of the hexagonal cell component. With a higher output of U and V value, it will result in a darker interior as the surface opening gets smaller and with a lower U and V value of the division of the surfaces will it allow more light to enter into the space.
SUCCESSFUL ITERATION 2: Although I have manipulated the definition by replacing them with other cell components like Triangle, Diamond and Quads, Hexagonal cell is still the most successful and appropriate component. By using the hexagonal cell component help to achieve a form that is structurally biomimicry. SUCCESSFUL ITERATION 3: I manipulated the base geometry of this form to look like a “cave”. While retaining the Triangular cell grid component on the surface, this turned out to be the most successful iteration out of the other cell grid component due to the complex spatial quality it created within.
SPECULATION I started generating my iterations with the consideration of it being incorporated into my chosen site and interesting forms started to be created. Instead of looking at it as a gathering space as it was originally intended for, I can start looking at it as a new entrance way into CERES. Perhaps an entrance way with the spatial quality similar to the successful iteration 3 that will draw pedestrians in. As for successful iteration 1, I tried to achieve a base geometry shape that was in respond to the chosen site, however due to the definition’s restriction, I was only able to achieve a small part of it. Perhaps I can start looking into Kangaroo Physics and SpringFromLine component that will allow for a more flexible form finding process. Lastly, for successful interation 2 being structurally biomimicry, I can consider varying the thickness of each panels. With the increase in thickness of selected panels at the lower part of the structure, it will not only make my structure stronger but also perhaps counter the site’s flood issue.

Technique Prototypes
Prototype 1: Exploring tied joints and hexagonal shape
With the ideas derived from technique
developments, I thought about producing them into a 3-dimensional models. It is useful because what may seem to work on Grasshopper might not necessarily be constructable in real-life. In the process, not only do I learn about the constructability of a model, but also I started thinking about ways to fit the elements together. I also started to see how different joints can affect the look of the structure. For example, prototype 1 uses a tying joint where 2 pieces of panel are secured together via a metal cable wire. It appears to be almost flushed with the panels whereas in the slotted joinery prototypes, it seem to be expressed as part of the design. With the 3 slotted joinery prototype, I realized that the joinery makes a difference to the overall spatial and aesthetic quality of the structure. It can either be â&#x20AC;&#x153;concealedâ&#x20AC;? or expressed as a design element. Also, while making the prototypes, I have learned that the arrangement of the panels will result in perforation of varies shape and sizes. This will in turn create a variety of selection of shadow casted by the simple manipulation of joinery detail. These prototypes satisfy the requirement
of the brief of the structure being a selfcomissioned architecture. Material chosen for the prototypes are grey boxboard from FabLab, besides the fact that the card cutter was out of service, I thought grey boxboard was an interesting material to look at because although it is a basic material, I found that prototypes 2, 3 & 4 were very stable and has potential of being a structurally sound modular cell. However, I do think that I will be using a different material for the final model. To produce these prototypes, I have tried to use grasshopper definition to fabricate however it did not work as I expected and was running out of time. Thus, I resulted in drawing each pieces in Rhino file instead. For the production of my final model, I do hope that I will be able to prefabricate my model using the fabrication grasshopper definitions given. From these prototypes, I have realized that I have full control of the light and shadow play that will affect the overall spatial aesthetic value of the structure. With a simple change of patterning on each panels and also the density of the U & V value of the grid system. 63

B.5: Technique: Prototypes
Joint Type 1 prototype: In this prototype, I have chosen a simple grid system of triangles with simple triangular patterning on them. The joinery to fix the panels together is a simple cross that allows 4 panels to connect together and also an asterick that connects 8 panels
Prototype 2: Cross/Asterick Joint Joint Type 2 prototype: Retaining the same grid structural system and pattern as the previous joint type, this joinery is a perfect circle with either 4 or 8 cuts that allows varies panels to connect together.
Prototype 3: Circular Joint Joint Type 3 prototype: With the same grid structural system and patterning on each panel as the previous prototypes, this joinery was derived from a square. It allows 4 or 8 panels to connect at each time.

A New Entranceway
Existing signages directing to CERES Park are badly vandalized and unclear.
I have chosen to design a new entranceway
from Merri Creek Trail leading into CERES Community Entrance Park. The structure will be a form that sits at the junction where the existing pathway leading to CERES Park and Merri Creek Trail meets. In comparison to man-made constructions natural biological constructions exhibit a significantly higher degree of morphological differentiation. This allows a higher performance and resource efficiency and this is why my proposed design structure will be structurally biomimicry. This will help to achieve the brief of self-comissioned architecture that will express and support
continuous relationships between technical, cultural and natural systems. Major human circulation path was observed along Merri Creek Trail with activities like strolling, jogging and cycling. Although CERES Community Environment Park has an existing pathway that connects to Merri Creek Trail, the directional signages are badly vandalized and unclear. Thus, this hinders the wayfinding of pedestrians into CERES Park. My aim for this project is to attract more citizens into CERES Park.

sing computational software like Grasshopper allows me to extend my ability to explore new ideas. The processing of information and relationship of elements which constitute to the site chosen provides a framework for negotiation and influencing the interrelation of datasets of information, with the capacity to generate complex form and structure which can be expressed as an algorithm. Looking at form finding for my structure in particular, in order to reach my goal, the form will have to respond accordingly to the chosen site.
should perhaps start looking into form finding via Kangaroo Physics. The tool of SpringFromLine is probably the most appropriate tool to achieve the desired form.
I started to look into the form derived from the chosen site by manipulating the base geometry in my algorithm definition (as shown below). Although it manipulated the overall form of the structure, the shortcoming of this method was that the intented form was unable to be fully achieved due to the limitation of my grasshopper definition. To overcome this, I
Geometry and patterning on each panel allows for perforation. And with that, varies openings will be achieved by either panels overlapping each other in a different plane or the detailed joinery that affected the quality of light and shadow within the space as shown on page 65.
I would also like to use HexagonPanel component to achieve a form that is structurally biomimicry. That being said, I would also like to look into how to create trianglular paneling within each hexagon shape as it will give the hexagonal cells more support with the extra structural support within.

Objectives/ Outcomes Week Eight
B.7: LEARNING OBJECTIVES/ OUTCOMES
Learning Objectives & Outcomes
With the use of Rhino and Grasshopper, it
gives me a clearer perspective of the buildability in a digital scale. With this understanding, I was able to easily identify and experiment different possibilities in terms of structure flexibility allowance and spatial quality. From this point onwards, I was able to begin discover more ways to generate a range of possbilities. I was able to anticipate and readily accept the criticisms by openly discussing about the shortcoming and limitations of my proposed designs as shown in my technique proposal section and the reverse engineer for ZA11 Pavilion. During my interim critique session, I was told that my precedent studies(Research Pavilion 2011 by ICD/ITKE) that I have shown during the presentation seems to have no link to my proposal, however in my defence I was actually discussing about the inconsistent hexagonal cells that were derived from the form curvature and discontinuities. I found that the technique is relevant to what I will be doing next for my form finding. But perhaps when presenting the precedent case study, I did not explain myself clear enough on that part. I was able to engage in self-directed learning of visual programming and in algorithm construction and thus acquired the ability to generate a variety of design possbilities with given situation as shown in Case Study 1 where I was given a grasshopper definition of my chosen Research Field and was able to explore and understand the possbilities of the definition by changing the existing parameters, inputting geometries and replacing component options. While uncovering the latent potential within the defintion, I was able to generate iterations that were mainly around the potential of it as an architecture. This is a very interesting way of learning as I start to experience â&#x20AC;&#x153;research by
designâ&#x20AC;? as coined by Rivka and Robert Oxman. Besides that, in Case Study 2, I was required to reverse engineer a chosen project of my Research Field. It was tough at first because I approached it the wrong way, but after researching online around the grasshopper community, I found similar tutorials that could be incorporated into my project. Although there were obvious difference between my reverse engineered model and the original, I was able to develop a personalized repertoire of computational techniques as shown in the technique development through 3D digital models. Eventually I started to investigate the scale, material effects and geometry base on those techniques as shown in my Technique Prototype section. The realization that even a small detail like joinery can make a difference to the spatial quality captured my interest. I was also able to investigate the issues of fabrication and assembly through the making of physical prototypes. As stated in that section, I had problems producing pieces from grasshopper and thus I will have to look into this for the next part. My knowledge for Grasshopper and Rhino is slowly progressing as time pass. I feel that these are softwares that are hard to teach in school and can only be learnt by self-directed learning through online tutorials. I would not say that I am very knowledgable with these softwares but I do feel comfortable using them now. However, I hope to be able to speed up my process of dealing with it each time as I realized that I spent too much time figuring things out and tend to neglect the aesthetic aspect due to the time limit.

Algorithmic Sketches
For our algorithmic sketchbook, we were
tasked to explore fractal geometry by using an equilateral triangular polygon shape that will be turn into a tetraherdron. As the diagrams shown on page 75, I was able to achieve pleasant results by simply manipulating the definition. I have also learnt that by activating the sun path and ground plate, it allows me to generate renderings of my iterations with better graphical qualities. The shadows casted gave an interesting way to look at the overall iteration.
76
We were given the definition of a tree to play around with and on page 76 and through these series of manipulation, I was able to understand the relationship of each component. I have also added materials on the model and rendered them to see a contrasting difference between the original. Using these new found skills, I will be able to incorporate them into my design proposal.
