I would like to “drape” a perforated mesh using something like a “cloth” (mesh plane) to fall down and collide with the perforated mesh, covering the holes by tightening the cloth so that it doesn’t fall through the holes. I found an example of a mesh colliding with a Brep, using SPC component (SolidPointCollision). This example:
(The GH: Self collision 2018.06.27_mcneel_forum2.gh (32.0 KB)
However, in my case the target for the collision isn’t a solid Brep, it’s an open Mesh, and I couldn’t find a component which directly handles mesh-mesh collisions. The collision I want is a kind of “Drape” over the mesh which is full of holes (to be covered):
I have tried the Rhino Drape command, but it seems the draped surface “falls through” the holes, and I can’t find any option making the “drape” stiff enough to stay on top of the mesh (slight downward “dents” is acceptable, if only the holes (tunnels) are essentially covered).
I also want the “drape” surface to have marked creases where it hangs over sharp edges so I can cut the “drape” using sharp weld angle (near 90º).
Is there any GH example where I can find out how to make such a “drape” collision between two meshes?
