I have implemented a verlet integration system and I need to change the color of the lines according to the pressure applied to this section. And I have a question here, what would work better as relevant points and lines, HISM, procedural mesh, or something else? And won’t changing materials during simulation have a big impact on performance?
Doesn’t really matter to performance if you make the material right.
(No textures, simple color variable)
The real cost is in keeping textures in memory.
Shading something a different color is almost trivial.
