首先我们得声明所需要的对象。当然我们需要一张用来渲染的U理。此外，我们q需要两个Surface对象。一个是用来存储后台~冲区，一个用来当U理的渲染对象。后面我再详l介l它们。另外我们还需要两个矩阵，一个是用来当纹理的投媄(jing)矩阵Q另一个是存储原来的矩c(din)?br>
LPDIRECT3DTEXTURE9 pRenderTexture = NULL;
LPDIRECT3DSURFACE9 pRenderSurface = NULL,pBackBuffer = NULL;
D3DXMATRIX matProjection,matOldProjection;
现在我们来创建纹理。前两个参数是纹理的宽度和高度，W三个参数是U理的多U渐q纹理序列参敎ͼ在这里是设ؓ(f)1Q第四个参数非常重要而且必须设ؓ(f)D3DUSAGE_RENDERTARGETQ表明我们所创徏的纹理是用来渲染的。剩下的参数是指纹理格式，点~冲区的内存位置Q和一个指向纹理的指针。当U理是用来当渲染对象Ӟ点~冲区的内存位置必须设ؓ(f)D3D_DEFAILT?
g_App.GetDevice()->CreateTexture(256,256,1,D3DUSAGE_RENDERTARGET,D3DFMT_R5G6B5,D3DPOOL_DEFAULT,&pRenderTexture,NULL);
Z讉KU理内存对象Q我们需要一个Surface对象Q因为D3D中的U理是用q样的一个Surface来存储纹理数据的。ؓ(f)了得到纹理表面的Surface,我们需要调用方法GetSurfaceLevel() 。第一个参数我们设?Q第二个参数Z个指向surface对象的指针?br>
pRenderTexture->GetSurfaceLevel(0,&pRenderSurface);
下一步就是创Z个适合U理l数的投q阵，因ؓ(f)U理的横U|和后台缓冲区的不一栗?br>
D3DXMatrixPerspectiveFovLH(&matProjection,D3DX_PI / 4.0f,1,1,100);
在我们的循环渲染之前Q我们必M存后台缓冲区和它的投qc(din)?br>
g_App.GetDevice()->GetTransform(D3DTS_PROJECTION,&matOldProjection);
g_App.GetDevice()->GetRenderTarget(0,&pBackBuffer);
渲染循环函数可以分ؓ(f)两个部分。第一部分是渲染到U理的过E。因此，渲染对象必须设ؓ(f)U理表面。然后我们就可以把东西渲染到q个对象上了。渲染到另一个表面上和正常地渲染到后台缓冲区差不多。只有一点不同，那就是先不调用PrensentQ）(j)函数Q因为纹理上的内容ƈ不需要显C在屏幕上。象qx一P我们先要重置表面颜色~冲区，q且调用BeginSence()和EndSence()Ҏ(gu)。ؓ(f)了能够适当的渲染，我们必须讄和纹理表面相W的投媄(jing)矩阵。否则最后的图象可能被扭?br>
//render-to-texture
g_App.GetDevice()->SetRenderTarget(0,pRenderSurface); //set new render target
g_App.GetDevice()->Clear(0,NULL,D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER,D3DCOLOR_XRGB(100,100,100),1.0f,0); //clear texture

g_App.GetDevice()->SetStreamSource(0,pTriangleVB,0,sizeof(D3DVERTEX));
g_App.GetDevice()->DrawPrimitive(D3DPT_TRIANGLELIST,0,4);
g_App.GetDevice()->EndScene();
渲染循环的第二部分就是渲染最后场景的q程Q也是昄到屏q上的过E）(j)。渲染对象重新设为后台缓冲区Q投q阵重新设为原来的投媄(jing)矩阵。由于纹理已l准备好了，所以它和纹理层0相关联?br>
//render scene with texture
g_App.GetDevice()->SetRenderTarget(0,pBackBuffer); //set back buffer
g_App.GetDevice()->Clear(0,NULL,D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER,D3DCOLOR_XRGB(0,0,0),1.0f,0);

g_App.GetDevice()->DrawPrimitive(D3DPT_TRIANGLESTRIP,0,2);
