| Abstract: |
| This paper presents a terrain partition algorithm for quick rendering.
The algorithm recursively divides the whole terrain into several equal blocks.
By analysing the amount of target in a terrain block and the ratio of the
blocks which contain no targets, it can find out an optimi
zed way. Furthermore, a terrain coloring method is presented, which blends textu
r
e image generated by DiamondSquares, and the vertex color. The terrain renderi
ng by this method has a realistic effect and clearly color layers. Finally,the c
ruising method in 3D scene used for 3D displays of anticolli
sion radar is introduced.The method has been successfully deployed in engineerin
g and has achieved a good effect. Otherwise, the method also adapts to general t
errain rendering. |
