Hello. Is there any idea if there is any way to create the command drape in grasshopper? I tried with kangaroo but I would like to do it exclusively with grasshopper. Thank you.
Drape is fast because it can use the Z-buffer data from the display, you can mimic this in pure GH, but it won’t be fast because you’ll end up doing a lot of mesh-ray intersections.
You must first combine all your shapes plus the ground-plane into a single mesh. You then generate a grid of points above this mesh, and use the Mesh|Ray intersector to find the points on the mesh underneath each grid point.
