Gray-Scott: whatever the surface

in this post, you will find

  • the modeling
  • pictures of the evolution
  • some variation
  • and the 3dxml at the bottom

The modeling

As far as it can be meshed, whatever the surface, we can apply on it the same pattern as previous post.

The trick is to replace the initial list of "pixels" from the flat square, with the list of "pixels" that you got from meshing a more complex (multicell or whatever) surface.

To mesh a surface, you need to access the mesh library, which is available with any license that includes Generative Shape Design (GSD) or Imagine and Shape (IMA), or Creative Design Experience, or Terrain Preparation. Basically, as far as you have a "CATIA Design" role installed already, you are OK.

Delete le link between the "Flatten" feature and the Hexagonal grid, and replace with the Fill input from the meshed surface, the purple arrow.

Along with the new initial base surface, the location of the initial B substrate must be adjusted. In this case, I used 2 spheres instead of 2 disks.

Picture of the evolution

Fill 0.035, Kill 0.06, from 1stp to 5000. I wish I knew how to make a video...

Variation with Kill 0.062
