注意点
- 需要安装dx9.0和vs2019设置，可以参考这个
- 顶点缓存6个面中后面和下面是以左下角坐标逆时针写的，其他面都是顺时针的，这样导致画每个面的三角形按照顶点的渲染方式不一样，为什么后面和下面这样去渲染呢？如果6个面按照同样的方式就会有显示错误。
代码
- Vertex.h
structVertex{
Vertex(){
}Vertex(float x,float y,float z,float nx,float ny,float nz,float u,float v){
_x = x; _y = y; _z = z;
_nx = nx; _ny = ny; _nz = nz;
_u = u; _v = v;}float _x, _y, _z;float _nx, _ny, _nz;float _u, _v;};#defineFVF_VERTEX(D3DFVF_XYZ | D3DFVF_NORMAL | D3DFVF_TEX1)- Cube.h
