Hello,
I’m working on a system that requires a deformable surface. That is to say a surface I can carve into. I’m having a hard time finding a starting point for research, hopefully just because this type of surface has a special name I don’t know.
My current surface is a simple triangular mesh. When I position the mesh in the world space it is aligned so that it’s normal is parallel to the most common direction of carving. I then have a sphere I can fly about which does a hit test with each vertex on the surface. If a hit is positive the vertex is moved away along the surface’s relative normal.
This worked quite well but as the project expanded the surface limitations became a problem. As the vertex motion is only along the z-axis I’ve only produced a 2.5D surface. I now need to be able curve the surface around on itself. Also I need to be able to tunnel into the surface making a full 3D surface necessary.
If anyone can offer any help I’d really appreciate it, even if it’s just a search term, as I’ve had no luck so far.
Thanks,
Maxwell.
