The reflection vector is computed from the input vertex position and normal vector 反射向量是从输入顶点位置和法线向量计算出来的。
Normal vector and directional vector are used for solving space problems or linear problems 巧用法向量与方向量解决空间平面及直线问题
Nor : uses the direction of the normal vector as coordinates . this is very useful when creating certain special effects ( see below ) 法向:使用法向量的方向作为坐标。这在创建某些特效时非常有用(见下文) 。
The key geometry information such as normal vector and main curvature etc . were firstly calculated by local approximation of measurement points with paramet 最后,总结本论文研究工作的主要结论,并对后续研究工作作了展望。
In order to get the better effect of showing organ surface , it also gives a new method to compute the normal vector at grid vertex for the drawing part of the system 在系统绘制部分,为了获得更光滑的器官表面显示效果,给出了网格顶点法向量计算的新方法。
