Let's play with the parameters and setup of the reaction-diffusion equation to create cool effects. You may work with a partner for this lab. Please choose 3 of the following 5 puzzles/tasks to complete this lab. Additional puzzles/task may be completed for extra credit.
Download and open Houdini with the ReactionDiffusionPlayground.hipc file found in this repository.
Modify the feed rate to create a cell mitosis (cellular division) affect.
The other parameters will be as follows:
D_A = 1
D_B = 0.5
kill_rate = 0.0608
delta_time = 1
Reference Image
My Result (Solution)
Feed Rate set to 0.0308
Modify the kill rate to create an simulation that reaches equilibrium very quickly. The rings should be approximately where the starting seeds were, and there should be little change between the 5th and the 100th frame.
The other parameters will be as follows:
D_A = 1
D_B = 0.5
feed_rate = 0.055
delta_time = 1

Frame 5
Frame 100
My Result (Solution)
Kill Rate set to 0.065

Modify the diffusion rate of chemical B (D_B) to create a simulation that still demonstrates where the seeds were at the start of the algorithm. There should be parts of concentric circles surrounding each seed location. To see if you're on the right track, run the simulation and then check (or have a friend check) and see if you can idenitfy where all the seeds were at the start of the algorithm!
The other parameters will be as follows:
D_A = 1
feed_rate = 0.055
kill_rate = 0.062
delta_time = 1
Seed Placement
Frame 100
My Result (Solution)
D_B set to 0.29

Modify the shape, size, or placement of the seeds in the playground to create an interesting effect. Which node might you need to adjust? How can you change the exisitng VEX to create something interesting?
Modify some of the parameters to create a cool effect. This effect can be displayed with a video or image, depending on whether you want to showcase the animated effect or the algorithm's result.
