Thanks for the opinions in advance.
I have a 2d line that I want to draw onto a 3d surface (a vertical drape, so the vertex x/y are constant, and the elevation of each vertex is adjusted to surface). I am currently adding a large number of vertexes, and using octrees to find the pertinent face, and pull an elevation by raycasting onto the face.
It occurs to me that a better alternative would be to “walk” over the faces, adding a point wherever two different faces touch.
This seems like something that has probably already been done, but I can’t seem to find anything by googling. Any advice?
Here is a picture of the desired result.
