不解。D3D开启深度缓冲后，纹理就贴不上了。关闭了才可以贴上？

	D3DXMATRIX proj;
	D3DXMatrixPerspectiveFovLH(

		(float)600 / (float)600,
		1.0f,
		1000.0f);
	g_pd3dDevice->SetTransform(D3DTS_PROJECTION, &proj);

如果把注释的两行
//d3dpp.EnableAutoDepthStencil = true;
//d3dpp.AutoDepthStencilFormat = D3DFMT_D24S8;
加上，就画不出了，没加上的话可以。。

不解，请教论坛里有经验的大大们。。非常感谢！

补充一下，
顶点格式：
D3DFVF_XYZ | D3DFVF_DIFFUSE | D3DFVF_TEX1

顶点结构：
struct hgeVertex
{
hgeVertex(){}
hgeVertex(float x, float y, float z, DWORD col, float tx, float ty):x(x), y(y), z(z), col(col), tx(tx), ty(ty){}
float x; // screen position
float y;
float z;
DWORD col; // color
float tx; // texture coordinates(uv)
float ty;
};

解决了。。是深度缓冲格式不对
