- wwwwiiiinnnnddddoooowwww specifies the position and size of the rectangular viewing frustum
- closest to the eye (in the near clipping plane), and the location of the
- far clipping plane. All objects contained within this volume are
- projected in perspective onto the screen area that vvvviiiieeeewwwwppppoooo defines.
-
- When the system is in single matrix mode, wwwwiiiinnnnddddoooowwww loads a matrix onto the
- transformation stack, replacing the current top matrix. When the system
- is in viewing, projection, or texture matrix mode, wwwwiiiinnnnddddoooowwww replaces the
- current Projection matrix and leaves the ModelView matrix stack and the
- Texture matrix unchanged.
