How do you keep track of how something is rotated? I know hod to do rotation along 6 basic axis, but what I want to do is have a constant (static, doesnt change) position and re-calculate the angle every at re-draw. This keeps a figure from getting warped, AND makes it so you can rotate on a plane that has been rotated.
I noticed that the TI89 uses something called "eyes" to keep track of where the camera is around the figure and at what angle.
Can anybody tell me how to do this or any other strategy that will work? otherwise I will have to keep a list of every preiouvs rotation, which will slow things down more and more as it goes along
