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 Ė 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 Ė 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.

Learning to work with a complex simulation using reaction-diffusion as an example.Initial exploration of Reaction-Diffusion as a form making system by implementing a different types of reactions as control technique. Both the mostly used Gray-Scott as well as the Fitzhugh-Nagumo reaction.Exploring different starting conditions as well as changing various parameters of the reaction through space to create variation in the simulation.Gray-Scott Ė F and k parameters of the reaction are fixed whereas the diffusion rate of U change through space.

The task was to explore the reaction-diffusion simulations and modify them to create the images. This images should explore how the patterns change when I vary parts of the process througth space and time.I used the 2-d Arrays to very the Diffusion rate and tryed out different reactions.

This assignment explores the Reaction/Diffusion processes, and one particular among them – Gray Scott Reaction/Diffusion. In this assignment, I used one reaction as an animated brush that bounces around the screen with changing speed, while the reactions in the background are changing their parameters.
