I generate a mesh using a 3D modeling program. It gives me all the points and normals for the static case.
Now in my program I would like to have the user deform my mesh when they press on it. This requires me to re-calculate the normals for the points that are touched.
Does anyone have suggestions on how I can quickly calculate all the normals for the points that get deformed. Are there any algorithms out there that can help me out?
