We had to design three 3d-printable cups using reaction diffusion.The three designs had to be substantially different from each other.The maximum dimensions of each cup were 6x6x8cm. The minimum wall thickness is 1.6mm . Possible ways to make a 3d-printable cup : time extrusion sketch,3d reaction-diffusion sketch, mesh based reaction diffusion.To generate a cup shape with these methods we had to find the ways to constrain our reaction to a cup-like shape  for instance: changing f,K through space and/or time,changing the diffusion rates through space and/or time,changing the initial conditions,remove concentration in certain locations to create a void,distort a RD mesh.

Final task of the workshop with Nervous System was to design three 3d-printable cups using reaction diffusion.I used the following 3 techniques developed through the workshop to constrain the reaction to a cup-like shape. All using the Gray-Scott Reaction.

CUP #1 Ä– Time ExtrusionIntroducing anisotropic diffusion of chemical u by having different diffusion rates in the x and y directions to create asymmetry.F and k parameter of reaction are changing through space.Controlling mesh generation by continuously restraining reaction-diffusion to happen within a set of law curves defined by mathematical formulas. Actually constantly controlling the concentration of the two chemicals to create void or solid.

CUP #2 Ė 3D Setting up an initial concentration of the two chemicals within a box to start the reaction-diffusion.Diffusion of chemical V is fixed. But the diffusion rate of chemical U changes through space so that it diffuses 2 times faster than V in the X and Y direction but diffuses with the same rate as V in the Z direction.

CUP #3 Ä– Mesh DistortionDistorting a regular mesh of a cup by using information from a Reaction Diffusion simulation to modulate the mesh.Diffusion rate of chemical U is 4 times faster than chemical V3 cups are generated by using different parameters for F and k in the equation of the Gray-Scott Reaction

These three projects conclude the workshop with Nervous System. The final assignment was about making an industrial product (cup) using forementioned processes. First design is a cup, where the RD on a 3D mesh object is used for forming the outher shell of a cup. For the second and third design RD processes growing in 3D were used to make a different rounded shapes. These specific shapes were based on the specific RD parameters that were chosen because they give the rounded half closed forms – suitable for storing things. Second design is a combination of an aquarium and flower vase, and the third design is a spatial instalation that shows the creative potential of using these volatile processes.
