Step 1: Simulation Reaction-Diffusion Pattern

make Reaction-Diffusion Pattern to Bear 3D model.
3D model is made by hisashiIMAI ( http://www.thingiverse.com/thing:37321 )
I used Nervous System's blog Archive as reference for make simulation.( http://n-e-r-v-o-u-s.com/blog/?tag=reaction-diffusion )

反応拡散模様を描く

Step 2: Cut Surface Along Texture Edges

on the previous simulation, I coded processing to cut surface along pattern's edges.

なんと模様のエッジにそってポリゴンをカットできてしまう

Step 3: IsoSurface and Smooth

Step 4: 3Dprint With Replicater 2
