As you see when the dust clears, we end up with a few lines of simple code. This is only because the 3D coordinates were in the VCS, which simplified the projection stage. As I mentioned earlier, the projection can be done using vertices in the WCS, but it would be more complicated. In fact we would just hide the WCS to VCS transform in the equations. The gains would not be very dramatic. Projecting a 3D Point on the Screen It is now time to implement a class that can do the projection and the WCS to VCS transform transparently, so that from now on you can forget the math. The Camera The camera has a very important role. It will transform a set of WCS vertices through the VCS and then project them to SCS. A caller can feed the camera with an array of 3D points, and in return it gets to borrow an array of two-dimensional coordinates. This array will be used to call the paint() method of an fPolyhedron. And with this array, we have completed the chain of transformations. The camera can have any position and orientation. Just place it in the WCS and tell it which direction to look.
