用于在地形插值及计算中间的各种各样的插值很好用-chazhia water intake, when drawing faster-moving flow towards the sediment bed, can increase the local bed shear stresses, resulting in bed erosion around the intake structure

海量散乱数据重构的小程序，采用B样条插值和分层B样条算法，对B样条算法进行了封装，最后OPENGL显示重构的网格数据。可用于人脸海量数据重构及地形重构。需先载入数据。数据格式可参考代码内格式。-Massive small scattered data reconstruction procedures, the use of B-spline interpolation and hierarchical B-spline algorithm for B-spline algorithm pack

实现三维地形模拟。地形网格采用随机网格生成法，在地形的绘制中采用多阶曲线插值的方法，最后采用三角形近似和纹理贴图。-3D terrain simulation. Terrain mesh using random mesh generation method, in terrain rendering using multi-order curve interpolation method, and finally the triangle approximation and texture.
