The script creates a random point on a given surface, checks the surface curvature at that point and creates a sphere with a radius that is inversely proportional to the curvature. The next (random) point cannot be placed within the existing sphere. As a result, a point cloud is created on the surface, with more points at the highly curved areas. The resulting triangulation therefore approximates the surface curvature with great accuracy.
