Mesh split

You can try mesh iso splitting but you will get triangular faces. For each vertex you have to put a weight could be X, Y or Z depending on the plane you want to cut. [image]

Marble fractal lines and foliation

Yes it is possible to apply this technique to sphere. [image] Bust instead of applying contour I apply Mesh Iso Splitting, so you need to put a value (double not point) at each vertex of the mesh then iso-splitting then colorize. [image]

Implicit surfaces

Hello Petras I have done a multiple iso splitting of mesh. It didn’t use exactly this algorithm. Hope it could help. [Canvas at 07;42;41] multiple_iso_splitting_mesh_LEGACY.gh (17.9 KB) See also these discussions

Dual color model design

Hello here is a solution using Grasshopper. As I understand you want to apply displacement and depending of the displacement colorize your mesh. I have done a mesh isoplitting which could be useful. I propose you a script that is doing a real egg shape as a surface. This surface is remeshed and some displament is added as a proportion on the height with a sinus. But you could imagine whatever function you want. and then iso splitting, enter a mesh, a value for each point and an iso value and…
