What is the easiest way to generate polygon meshes from constructive solid geometry? Marching cubes [4] seems pretty involved.
As I understand it, this is a Very Hard Problem. This is (one of the reasons) why there are so few converters from POV-Ray to mesh-based formats; it's highly non-trivial to tesselate CSG.
POV-Ray is pretty fast. I had contemplated just rendering a bunch of POV-Ray images to emulate a realtime 3D view. Images could be buffered up based on the current camera position. Another goal of the project is to generate 2D prints from 3D models. Any idea how hard is this going to be? Basically it needs to identify features (holes, edges, etc), then project these features to an orthographic plane, alone with associated dimensions. -Tom
