The Derivation of a Perspective Projection Matrix and Its Programming Implementation
Perspective projection is the foundation of the 3d graphic display. In this contest perspective projection matrix based on the mathematical model is discussed. Using this matrix, we can transform three-dimensional coordinate into perspective projection coordinate conveniently and display on the screen in realtime. Finally,with the example of 3d perspective projection data, we have shown the rendering of this perspective transformation and verified the validity of this method.
