| Abstract: | 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 real-time.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. |
