I'm looking for a way to generate curvature maps like this:
The map stores the Convexity and Concavity of each pixel as a value from 0 to 1, where .5 is no curvature and 1 and 0 are the extremes.
I searched for how to calculate the curvature of meshes and found these questions on StackExchange:
But I'm not sure if these are about the method actually used in the example.
What algorithm is used to bake these maps, and where can I find more information about it?
