毫米波防撞雷达三维显示界面的设计与实现

提出了一种地形分块加速绘制算法。算法递归地将地形划分为多个大小相等的地形块 ，通过统计地形块中目标分布的稀疏度以及无目标地形块所占的比例，寻找最优的地形分块 方式。此外，提出了一种利用Diamond-Squares算法生成随机纹理，并融合顶点颜色为地形 着色的方法，渲染的地形真实感强、层次分明。最后，介绍了防撞雷达三维显示中的场景漫 游方式。该方法已成功应用于实际工程中，显示效果良好，并且具有通用性，可以应用于一 般的三维地形绘制。

Design and Implementation of 3D Terminal Displays for Millimeter Wave Anti Collision Radar

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 Diamond Squares, 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 anti colli 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.
