INTRODUCTION
M
y name is Xiaodi Zhang (Dora), I am 21 years old and a third year student in Bachelor of Environments majoring architecture.
Born in Beijing, China, I have been studied in Melbourne since 2012. I used to study accounting in the foundation before the University. While accounting is boring for me, so I changed to study architecture because I like drawing and designing.
Architecture is a comprehensive career which intergrades multidisciplinary. The complexity of architecture itself is attracting for me because I found that architectural designing is related to plenty of precedent researches, science, landscape, etc. Also, using designing techniques, some architects create parks, furniture, products or even fashion design. I am really interested in the designing process of challenging and exploring the conventions with multidisciplinary.

MY PROJECT
I
learnt rhino skills and paneling tool skills in the subject of Digital Design and Fabrication. Digital technique allows me to expand the designing approach and design something that is extremely hard to produce by two dimensional drawing. It provides a quicker way to create and change the design for designers and it shows a shift from traditional design to computational design. I also understood the digital fabrication procedure of CNC machine and 3D printing. The fabrication skills with fabrication machines and variable materials are useful for further model making.

The project as a “democratic design” focuses on the sustainability of environments. 2 The park improves the regional ecological environments, and thus it leads to the direction of the city development which combines cultural inherence with ecology priority aiming to serve people’s livehood. It also has educational functions not only for science popularization but also for the increased potential of sustainable design in the future. As the project is finished by the integration of design and science, multidisciplinary is another emerging direction for design development in the future. 2.

THE WATER CUBE 2007, Beijing, China
Fig 5. The Water Cube
T
he National Swimming Centre, also kown as the Water Cube, was constructed for the Olympic Games in Beijing. The structure derives from the form of aggregated water bubbles in foam. ARUP designers represented the idea by dividing the space into cells of equal volume with the least number of surfaces and without gaps. As a result, the geometry is composed of repetitive units which makes the building to be easily built. Meanwhile, random appearance is generated from arbitrary angles as well. Thus, the facade and the structure are continuous element that works together, representing the water bubbles in aggregation through architectural expression. Computational techniques are used in both designing process and construction process. The geometry of the building was designed in computer directly as the form

is impossible to be represented by two-dimensional drawings accurately. Thus, computational design provides much more potential possibilities for architects and allows designers to experiment a variety of solutions as fast as possible. For construction process, ARUP relied on the algorithmic system to test the structural performance of different design configuration and easily make changes to the structural system. 5 As the architectural design has been shifting from the traditional design methods to the computational design, designers are required to have computational abilities which can utilize software expertly. However, software is just a designing tool which cannot replace appropriate decision making. Thus, designers should always focus on the idea itself and the functions and amenities of architecture.

he project was a temporary research pavilion designed by ICD and ITKE in 2010. The project was a material-oriented computational development and the final outcome turned out to be a bending-active light- weight structure made by plywood strips.
The project started with the material research of the elastic bending ability of plywood strips. Physical experiments were made to test the bending property of the material and the forces of the whole structure. Based on the material behaviors, the computational model contained with all the measurement of plywood deflections under bending and geometric information, and generated the required structural analysis model. The final physical model was made by 80 plywood strips after accurate detailed structural calculation generated by the computer. 6 6.

Computational technology is not only helpful for design and construction, but also important for experiments. The project indicates a new tendency of the integration of algorithms skills with researchedbased experimental design. 7 For younger generation of architects, â&#x20AC;&#x153;research by designâ&#x20AC;? is regard as an emergence of architecture field. Multidisciplinary research now is becoming a fundamental approach for experiments and exploration of computational geometry. In this case, the material research is predominant in the designing process as it directly influenced on the geometry. With computational techniques, material design is shifted to be a significant part in architectural design since it may provide potential possibilities for structure and form.

SWARM INTELLIGENCE Tyler Julian Johnson, 2010
T
he project is a generative design using computational techniques based on the research of swarm intelligence.
Fig 9. Emergent Architectural System
The swarm system in this project relates to the swarm behavior of people with an attractor. Attraction agents and peopleâ&#x20AC;&#x2122;s movement is recorded and inputted into the computer to generate diagrams of patterns (Fig. 8). Using the research as a basis, the architectural design is developed according to the geometry of the pattern. 8 Using the generative design method, designers are able to create the a generative logic, which provides a range of possibilities and automatic fashion for further development. 9 This methodology contributes to the creativity and exploration from the nature and surroundings.

However, for most of the time, generative design only creates a dramatic geometry without functioning. Designers should use generative design as an approach for finding a creative form and put efforts to design the functions and amenities as well.

T
he project uses computational technique to explore the performative capacity of sand dollarâ&#x20AC;&#x2122;s biological structure and express it in architectural form. Manufacturing processes are also under the computer control which automatically calculate the effectiveness of a range of geometries. The pavilion is finally built by thin sheets of plywood with CNC machines cutting the material piece by piece in the particular angle. As shown in Fig. 10, the form of the pavilion is consist of a series of modular and the form is developed by making geometric variation of the components. Since the modular are linked together at edges, the change of a single unit relates to the difference of the whole structure. 10
Generative and parametric design methods allow a form transforming consistently and continually under changes of parameters, which provides harmony and unity to the geometry. Unlike the conventional design, the emphasis of generation shifts to the designing process because the form keeps changing through the process, as well as the performance of structure and material. With computational techniques, designer can change any step of process efficiently and effectively.

A.4. CONCLUSION
I
n Part A, I learnt that how design can be used for nature and how computation influences on design process and outcome.
Design Futuring introduces how design serve for nature and people. From ethical aspect, design is not an isolated artificial product. Rather it should be considered holistically as a project contributes to the sustainability of the environment and peopleâ&#x20AC;&#x2122;s lifestyle. In addition, good architectural design can relate to the context and broaden the functions for people. Potential possibilities and innovation are key values that designers should to explore. Design Computation and Composition/Generation illustrate how computational methodology applies to and influence on design. Shifting from conventional design to computational design, designers are able to create and test more possibilities and change the designing step quickly and easily by using computers. Research-oriented design and generative design are emerging and developing through digital technology. Under this background, designers for younger generation are required to have computational skills and multidisciplinary knowledge. Parametric design is my intended design approach. Instead of a specific shape, designers create a sequence of parametric equations to generate the geometry. It brings infinitely potentialities for designers, which attracts me by the algorithmic logic and variable possibilities.

A.5. LEARNING OUTCOME
B
efore I study this subject, I categorized all the projects made by computers as digital design. After the reading and lecture, I understand the categories of digital design, and how computational design benefit to design process and bring possibilities for design and developing directions. Furthermore, I also realize that there is ceratin risk for design computation. Although parametric design and generative design could generate fantastic geometry, a good project could not be created without plenty of analysis for functionality and amenity. Focusing too much on poetry aspect will result in less decision making for designers. My previous design were all carried out by rhino with compositional designing method. By learning the theories of computational design, I found that my previous design could be represented by algorithmic logic and hence the form could be changed and improved with a variety of possibilities quickly and efficiently.

iomimicry is a method for innovation which searches for sustainable solutions learning from the nature. It has been applied to the fields of architecture, energy, transportation, agriculture, medicine and communication. For example, engineers reduced the noise of High speed train by creating many structural small vortices. This is similar to the way an owlâ&#x20AC;&#x2122;s primary feathers have serrations that create small vortices instead of a large one (Figure 1).2 In terms of architecture, biomimetic Architecture is usually based on computational technologies applied in biomimicry methodology.3 Abstraction and integration of biological systems are used for forms, texture and construction. Learning from nature, the largest laboratory which ever existed and ever will, there are more possibilities of reinterpretation of materials and structure, and generation of form and pattern. Merging arts and culture with science and nature, Biomimicry methodology brings more creativity and meanings to architecture. On the other hand, although the dynamic form generated through biomimicry methodology is more aesthetic compared to traditional architecture and construction, it may not have the optimization of overall structural performance, which means it perhaps results in a loss of efficiency in resource and structure.

T
he Morning Line is a project which conceived as a collaborative platform to explore the interplay of architecture, art, cosmology and music. The Morning Line is formed by intertwining lines connecting to each other. The structure has no single beginning or end, only movements around multiple centers. Each bit of the structure is interchangeable, demountable, portable and recyclable which allows the piece to change over time. 4
Making the fractal structure by grasshopper, I scaled different shapes of geometry by a series of times in different order. The plugin of Bullant was used for finding the geometry of joining fractal units. Patterns on the surfaces and patterns in the space were drew based on the geometry of fractals. The patterns replaced the original geometry and made the entire geometry joinable.

Scaling the basic geometry for several times, the forms has been changed far away from the original shape and has became much more dynamic. The first two selections have scaling units joining to the original unit, which makes the fractal as a whole for further joining. The rest of the selections have more complex forms and achieve the aesthetic aspect by broken into pieces.
The pattern is drawn within the space of the single unit geometry. As it is a three-dimensional pattern without any opening, it could be a structure itself without the original geometry. The three-dimensional pattern provides more possibilities of geometry variations.
The pattern of the geometry makes the form more complex and also makes it possible to be assembled piece by piece.

The Tessellation of the fractals could be used for different shapes as different functions. The fractals have faces orienting to several directions, which makes more potentials for joining the fractals together to create dynamic geometries.

his project pursues the study of a micro tensioned element that is highly flexible in its form, easily connectable and geometrical aligned but at the same time appears organically arranged. A system is developed consisting of an easy geometrical principle, which becomes more complex through minor deformation of the single unit, and can be materialized as a membrane tensile element or a stiffened fibre-composite cell. Through this process the single element can be highly differentiated by several ways of manipulation and reaction to different parameters. 5

Materialisation The material of the prototype is the fabric that is tensile in two dimensions so that it could be stretched vertically and horizontally. Construction The structural frame was made firstly. Pin connection was used between balsa pieces so that they could have rotation movements. Then the fabric was sewed together and tied to the corners of the frame by fish lines.

Test Because of the rotation movements of the frame, the form of the fabric could be easily changed, which shows the tensile capacity of the fabric. Learning Outcome The form of the element is shaped by the frame. As a result, for the design project, the design of the frame is as important as the fabric element. Instead of a flexible frame, the frame for the design project should be rigid so that the model is possible to be stable.

Agenda Learning from the precedent, the outer structure of the litter trap should be tied to the ground anchors so that it wonâ&#x20AC;&#x2122;t flow away. The inner cage of the litter trap should be floating on the river surface and be easily removed for the convenience of cleaners. Tensile structure learning from the Reverse Engineering is chosen to be the basic structure for the project, because the material (fabric) is flexible and porous, which is suitable to be a filter for the river while does not impede water flow.

Inner Cage water flow
Litter captured in the litter cage
Shape The sphere form is selected as the basic shape for the inner cage because it is a closed surface which is easy for removal. Drawback The connection system for the litter trap still need to be clarified and test. However, the project is related to the site and is benefitial to the public and environment.

B.7. Learning Objectives and Outcomes
P
art B makes me have better understanding of the computational theories I read in Part A. In Part B, we are forced to understand each definition, each
possibility and each logic behind the script, which provides me with a deeper understanding about grasshopper skills and parametric design. As I was using Kangaroo for the Reverse Engineering and technical development, I learnt more about the property of mesh, the difference between mesh and NURBS as well as how the mesh could be divided or subdivided. Throughout the practice of Part B, I not only learnt how to use definitions but also learnt the logic of Kangaroo, Grasshopper and computational design.

also learnt the logical thinking of exploring a topic by listing species and making iterations. Using Grasshopper as a technique, I found that it saves a lot of time
as most of the details are recorded by parameters and I do not need to redo all the previous steps when I want to change a detail.
The model making process is harder than the computational designing. Designers do not need to really think about the strucutre or construction method when they generate a form by grasshopper. However, to make a physical model, one need to fully understand the property of the material, the construction joint and the load distribution. In order to show the tensile capacity of the structure, I made a physical model manually. I found that I have better understanding of how does the frame affect the fabric shape and how does the fabric and the frame work as a whole.
Generally, parametric design is challenging but exciting for me. I like to challenge the thousands of possibilities generated by parametric design.
