This was a task for a university-course. They gave us a framework and told us to implement the Loop-Subdivision algorithm. As an extra task, we should implement a rule for an adaptive subdivision scheme. Instead of some lame mathematic rule, I decided to go the hard way and cram something like a selection-painting into the framework, allowing the user to mark the triangles he wants to be subdivided by a mouse click-and-drag. It’s only a hacky solution and not really comparable to a real subdivision painting program like Sculptris, but it works and was fun anyway š
