I created a skin for a wall surface that conforms to the contours. It also expresses the information about the curvatures along the wall through acting like a mesh. The sides of the triangles curve inward or straighten out depending on the convexity or concavity of the surface. This system can be applied as a way of controlling privacy levels along a wall.
(I’m having some difficulty posting the diagrams. I’ll try to post them up later.)
