This class factors out a lot of work that needs to be done to position 3D objects at variable rotations, world coordinates, and screen distances. Use the link below to get the utility class. Using this class requires papervision. If you don’t already have papervision, then you probably don’t need this class… Also, the sample isn’t pretty (graphically), and the source has some weird key controls. They are completely unintuitive but get the job done for testing
