怎样在我的程序中使用"full screen anti-aliasing_全屏反锯齿(FSAA)"？

在OpenGL中使用ARB扩展ARB_multisample。在D3D中，设置D3DPRESENT_PARAMETER结构中的MultiSampleType项，并把这个数据结构传入IDirect3D9::CreateDevice()函数中。  例如，下面的代码使用4个采样点，进行多重采样：

D3DPRESENT_PARAMETER d3dPP;

ZeroMemory( &d3dPP, sizeof( d3dPP ) );

d3dPP.Windowed = FALSE d3dPP.SwapEffect = D3DSWAPEFFECT_DISCARD;

d3dPP.MultiSampleType = D3DMULTISAMPLE_4_SAMPLES;

pD3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dpp, &d3dDevice)

/************************************/
How do I force FSAA on within my application?

In OpenGL, use the ARB_multisample extension. In Direct3D, set the MultiSampleType value of the D3DPRESENT_PARAMETER struct passed into IDirect3D9::CreateDevice().  For example, this code snippet enabled 4X antialiasing:

D3DPRESENT_PARAMETER d3dPP;

ZeroMemory( &d3dPP, sizeof( d3dPP ) );

d3dPP.Windowed = FALSE d3dPP.SwapEffect = D3DSWAPEFFECT_DISCARD;

d3dPP.MultiSampleType = D3DMULTISAMPLE_4_SAMPLES;

pD3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dpp, &d3dDevice)
