立方体贴纹理问题

jing51536

一个立方体简单程序,相实现6个面贴同一张图纹理:

我的相关定义如下:

struct CUSTOMVERTEX
{
        float x,y,z,rhw;
        float u,v;
};
#define D3DFVF_CUSTOMVERTEX (D3DFVF_XYZ|D3DFVF_NORMAL|D3DFVF_TEX1)

CUSTOMVERTEX customVertex[]={
        {0.0f,0.0f,0.0f,0.0f,1.0f},  
        {0.0f,1.0f,0.0f,0.0f,0.0f},  
        {1.0f,1.0f,0.0f,1.0f,0.0f},  
        {1.0f,0.0f,0.0f,1.0f,1.0f},
        {0.0f,0.0f,1.0f,1.0f,0.0f},  
        {0.0f,1.0f,1.0f,1.0f,1.0f},  
        {1.0f,1.0f,1.0f,0.0f,1.0f},  
        {1.0f,0.0f,1.0f,0.0f,0.0f}
};
WORD indices[] = {
        0,1,2,0,2,3,        //前面
        4,6,5,4,7,6,        //后面
        4,5,1,4,1,0,        //左面
        3,2,6,3,6,7,        //右面
        1,5,6,1,6,2,        //上面
        4,0,3,4,3,7                //下面
};

但出来的结果只是这样的:



只有两面为本来图像.


请教大虾,如何实现6个面都显示图像.

顶,
求解...

struct CUSTOMVERTEX
{
float x,y,z,rhw;
float u,v;
};里面几个参数？6个吧？

CUSTOMVERTEX customVertex[]={
{0.0f,0.0f,0.0f,0.0f,1.0f},  
{0.0f,1.0f,0.0f,0.0f,0.0f},  
{1.0f,1.0f,0.0f,1.0f,0.0f},  
{1.0f,0.0f,0.0f,1.0f,1.0f},
{0.0f,0.0f,1.0f,1.0f,0.0f},  
{0.0f,1.0f,1.0f,1.0f,1.0f},  
{1.0f,1.0f,1.0f,0.0f,1.0f},  
{1.0f,0.0f,1.0f,0.0f,0.0f}这是几个参数？5个吧？
};

怎么不一致？

顶点的数据结构和FVF不对吧？
把rhw和D3DFVF_NORMAL去掉试试
