I'm looking for a way to sharpen geometry, for example, choosing areas with more curvature and making those areas have an even sharper curvature, eventually becoming a sharp edge. I tried to play around with the measure sop and point clouds, but haven't yet achieved the effect. There are some brushes in zbrush or mudbox that can do this, but does anyone have any link to a procedural algorithm or concept of how it could be done?
