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.
