用OpenGL编写的模拟地球、太阳、月亮三者运行状态的文件，可以用方向键操作它们的运动。自己写的代码，欢迎批评，-with OpenGL simulation prepared by the Earth and the sun, the moon three running in the paper, you can use the direction keys to operate their campaigns. His writing code, welcome criticism, il

该篇论文提供了三维立体表面模型三角网格相交性的快速检测技术。-This paper presents a method, along with some optimizations, for computing whether or not two triangles intersect. The code, which is shown to be fast, can be used in, for example, collision detection algorithms.

The Roamsteps code base offers an introduction to implementing the ROAM algorithm for accurate, high-performance display of large terrain datasets. The ideas the original 1997 ROAM paper have been updated significantly in many respects: the basic dat
