NV_V宏 NV_V宏进⾏向量赋值操作。如代码：NV_V(a, = , x);其等效于：a[0] = x[0];a[1] = x[1];a[2] = x[2];宏中间的操作符可以是 =，此时则换为：a[0] = x[0];a[1] = x[1];a[2] = x[2];2 NV_VV宏 NV_VV宏能实现向量元素操作。如代码：NV_VV(a , = , x...
NV_MAG2(x); 等效于: 2D: (x[0]*x[0] + x[1]*x[1]); 3D: (x[0]*x[0] + x[1]*x[1] + x[2]*x[2]); 2 NV_DOT NV_DO宏用于向量的点积。可以有多种用法,如下示例: ND_DOT(x, y, z, u, v, w); 2D: (x*u + y*v); 3D: (x*u + y*v + z*w); NV_DOT(x,...
3D: (x*u + y*v + z*w); NV_DOT(x, u); 2D: (x[0]*u[0] + x[1]*u[1]); 3D: (x[0]*u[0] + x[1]*u[1] + x[2]*u[2]); NVD_DOT(x, u, v, w); 2D: (x[0]*u + x[1]*v); 3D: (x[0]*u + x[1]*v + x[2]*w); ...
