dx纹理不显示，求教原因。

这是我的顶点格式
struct v
{
        v(float ix,float iy, float iz,float iu,float iv)
        {
                x=ix; y=iy; z=iz; u=iu; _v=iv;
        }
        float x,y,z;
        float u,_v;
        static const DWORD FVF=D3DFVF_XYZ|D3DFVF_TEX1;
};
渲染状态
        Device->SetTexture(0, Tex);
        Device->SetRenderState(D3DRS_LIGHTING, false);
坐标
        v1[0]=v(0.0f,0.0f,0.0f,0.0f,1.0f);
        v1[1]=v(0.0f,1.0f,0.0f,0.0f,0.0f);
        v1[2]=v(1.0f,0.0f,0.0f,1.0f,1.0f);
显示是黑灰色的 请问还有什么原因导致不显示纹理？

我找到了直接drawprimativ可以显示纹理，用MESH不可以。
那位高手帮我看看mesh设置有什么问题？
        pteapot->LockVertexBuffer(D3DLOCK_NO_DIRTY_UPDATE,(void**)&v1);
        v1[0]=v(0.0f,0.0f,0.0f,0.0f,1.0f);
        v1[1]=v(0.0f,1.0f,0.0f,0.0f,0.0f);
        v1[2]=v(1.0f,0.0f,0.0f,1.0f,1.0f);
        pteapot->UnlockVertexBuffer();
        WORD* index;
        pteapot->LockIndexBuffer(D3DLOCK_NO_DIRTY_UPDATE,(void**)&index);
        index[0]=0;
        index[1]=1;
        index[2]=2;
        pteapot->UnlockIndexBuffer();
        D3DXATTRIBUTERANGE attr[1]=
        {
                {0,0,1,0,3}
        };
        pteapot->LockAttributeBuffer(D3DLOCK_NO_DIRTY_UPDATE,(DWORD**)&index);
        pteapot->SetAttributeTable(attr,1);
        pteapot->UnlockAttributeBuffer();

不能显示纹理：
1）检查投影矩阵和视口矩阵
2）灯光、材质搭配。
3）Alpha通道
4）背面裁剪
5）贴图格式，TGA格式在D3D中比较容易出问题，建议用JPG、PNG、DDS。
暂时想到这些。

谢谢。已经找到原因是视口矩阵错了。
