CASE STUDY 1.0 LAVA GREEN VOID
The idea behind this project was to defy the traditional idea of the application of a structure. Green Void was created to test the possibility of creating more from a minimal structure. The form of the structure was a result of a study on the most efficient connection of different boundaries within a 3-Dimensional space. Inspiration came from cells, crystals to the formation of soap bubbles. What they were trying to achieve is creating a minimal surface structure that follows the forces of gravity, tension and growth (http:// www.archdaily.com/10233/green-void-lava/). Using the latest digital modelling and fabrication techniques, the form was created. The computer-model, based on the simulation of complexity in naturally evolving systems, feeds directly into a production-line of sail-making-software and digital manufacturing. Regarding the brief for our design, this project has the potential in generating a relaxed form for the structure and help us understand the principle of tensioned surface that is needed in creating the design for our project.

STUDY OF MINIMAL SURFACES & MATERIAL PERFORMANCE Green Void project revolves around how the structure can generate minimal surface through the formation of anchor points. Based on given 3D model and Kangaroo plugin definition, a study on how the tension can be manipulated using anchor points. It creates various possibilities of the structure to have minimum surface, just like how they wanted the structure to be lightweight. The study of the model also gives insight to how should the material perform the structure. It tests out the performative element of the material needed and how materials can generate the form of the project itself.

CASE STUDY 1.0 CRITERIA DESIGN
The first few iterations mainly manipulating the anchor points for the structure. Anchor points were derived from modifying the base curve for the form. Points were then added and subtracted to test the form that it can produce. Through Kangaroo plugin as well, the tension between different surfaces varies. This iteration shows the possibility of the form having a different sizes of surfaces.
Curve based on the basic form of Green Void was created and modified through the help of Exoskeleton. It creates different type of surfaces which are now forming tubes-like shape for the structure. It also shows how the structure can connect through this shape, creating an interconnected space and joint surfaces along the form. By altering the number of mesh and radius, it can generate various forms with different

GEODESIC CURVES SG2012 MATSYS GRIDSHELL This project was designed to test out the relation between structures and material performance. The structure is erected from straight wood members and bent to follow the geodesic curves that makes the structure. The wooden members form gridshell on a relaxed surface. This project focused mainly on constructing geodesic curves to form a grid system that can further be analysed to minimize material. In addition, a loop in between the geodesic curves allow the structure to have smooth workflow. It helps integrating the geometry, structures and material performance. Computational designing method was used to develop the gridshell system and in analyzing the material performance. It allows for optimal maximisation of the space while stil minimizing the material use. This case study explores another aspect of minimal surface structure. Even though it has rigid structural system, the grid system erected from the geodesic curves allow for flexible and organic aesthetic for the project.

OUTCOME FROM THIS PROCESS

CRITERIA DESIGN
After altering the gridshell definition, it is realised that the concept of gridshell is not really compatible with our class’ brief.Gridshell should be something that touches the ground. In regards to our brief, gridshell is too structural and rigid to be a suspendedflexible structure. Thus, a different approach was taken to find the form of the project. While still taking the idea of grid system, form finding through Kangaroo physics was taken to generate different forms for the project.

CRITERIA DESIGN
This project by Frei Otto shares the same method of form finding. Otto used gridshell as the basis shape and then created different possibilities of it in creating a form for the structure. Physics of how gridshell behaves when hanged was studied and analysized in this process. Taking on this approach, the form of a gridshell was utilised to generate a more flexible form for the brief. Using Kangaroo plug in, different forms were generated. The results are pretty satisfying as it can successfully create flexible structure with minimal surface, just like what had been discussed in the previous sections.

TECHNIQUE DEVELOPMENT part 02.
Based on the two case studies discussed above, the design approach consists of two specific areas: one is the relaxed and minimum surface inspired by Green Void to create a suspended structure and the other one is efficien design using grid system to minimise material use. Both approach includes the minimum surface aspect into the design as a form to test out the material performance. While the technique in case study 2.0 was explored, it was then apparent that the application of the technbique is incompatible with the design brief that we received. Thus, the change of approach was taken. As a starting point, the idea of curves forming a grid as an outer structure became the basis for the form finding process. Basic grid was created and then referenced to Grasshopper. Then Kangaroo plugin was utilised as a tool to apply force and to see how the tension can give various formation to the basic grid. From the simulation, different possibilities were generated and be analysed.

CRITERIA DESIGN
In relation to the site, the main control points that were referenced as the anchor points symbolise the supporting element of the structure, which is the exisiting trees on the site - as it is going to be hung and suspended off the ground. The distance of the anchor points were estimated accordingly to the condition on site.Then the height of the points represent the points where the structure is going to be hooked or hung. This process is more successful compared to developing the gridshell definition, as it is too structural to be applied to the brief. Using Kangaroo, the generation of the form was clearer and more buildable. Materialisation was more applicable as well compared to the gridshell technique. Thus, for this project, gridshell technique definition was shifted with the force simulation method in Kangaroo.

TECHNIQUE PROTOTYPE
In this prototyping process, poly string is used to represent net-like and fibrous material. Different connection methods were also tested to see which one is the most suitable one for the structure. The connection must support hanging and tension from the surface.

CONCEPTUALISATION
Weaving and knotting technique were chosen because it gives the most stability out of the tested connection types. It also still gives the flexibility that we want of this structure.

CONCEPTUALISATION
The design direction for the brief is incorporating both the ideas from the two case studies. Through the minimum surface and the grid system from the gridshell, the aim is to create a structure that can showcase the continuous relationship between the development of technology, social culture and also the natural systems that happen around people. This design is aimed to generate new possible outcomes of the combination of all the system mentioned above.
Site chosen is the Quarries Park playground, next to the Quarries skatepark. The reason being is that it has an interactive qualities with all the features that can engage different generations in one space. It has the potential in creating a space that cam ne utilised by both children and adults. Also, the space offers exposure as it has a high traffic with all the people going to the playground, skatepark, and passing through to and from the Merri Creek trail. Other than that, the site is located higher thanthe Merri Creek ground level, so it offers a clear view to the city. Lastly, the close approximity to the surrounding neighborhood is also a design consideration as it allows for more interaction of the people around Quarries park. CONCEPTUALISATION 25

LEARNING OBJECTIVES AND OUTCOMES
Throughout part B, we began to develop a “personal repertoire� in computational design. The process of generating iterations as much as possible and recreating definitions help us in understanding more about the computational design process. Having an understanding in the definitions really proved to be very essential in this design process. This was sure a very challenging and different process compared to the conventional way of knowing what the potential outcome and work towards it. Through part B, we learn to develop our understanding in a different approach of designing. Computational design generate more possibilities of outcome as it can output multiple variations within one definition. Parameter manipulation gives us the ability to invesitigate or design more thoroughly and thus can help us generate an optimised outcome.
