Anti-Aliasing
Author
When i create a mesh with textures in 3DS Max or blender, When using it in my game-application it looks like the pixel-game before Voodoo 2 3dfx came.
i want to use Anti-aliasing to smooth out the textures.
i am using Managed C# with a Geforce 8800GTX card.
i think it would be a preset of the 3ddevice but i don´t have the syntax and i can´t find it on the internet.
where do i start?
tnx prehand.
Hi, it may be multisample you are looking for
//here is some code to get the sample
//how to use it
//here is some code to get the sample
//------------------------------------------------------------------------------------//this will return the multisample that this device can support//we will start at D3DMULTISAMPLE_6_SAMPLES and work back wards if the card canmt support it//-------------------------------------------------------------------------------------void GetMultiSampleSupported(DWORD *pQualityLevels, D3DMULTISAMPLE_TYPE *type){ HRESULT r1, r2; DWORD QualityLevels = 0; D3DMULTISAMPLE_TYPE types[6] = {D3DMULTISAMPLE_8_SAMPLES, D3DMULTISAMPLE_7_SAMPLES, D3DMULTISAMPLE_6_SAMPLES, D3DMULTISAMPLE_4_SAMPLES, D3DMULTISAMPLE_3_SAMPLES, D3DMULTISAMPLE_2_SAMPLES}; for(int ctr = 0; ctr < 6; ctr++) { QualityLevels = 0; r1 = D3D->CheckDeviceMultiSampleType(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, D3DFMT_A8R8G8B8, FALSE, types[ctr], &QualityLevels); if(SUCCEEDED(r1)) { //QualityLevels = 0; r2 = D3D->CheckDeviceMultiSampleType(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, D3DFMT_D24S8, FALSE, types[ctr], &QualityLevels); if(SUCCEEDED(r2)) { //we can use this sample so lets set it *pQualityLevels = 0;//QualityLevels; *type = types[ctr]; //TCHAR buff[MAX_PATH]; //sprintf_s(buff, MAX_PATH, "QualityLevels = %d, Sample Level = %d", QualityLevels, types[ctr]); //MessageBox(Hwnd, buff, "AppWin::GetMultiSampleSupported()", MB_OK); return;//where done }//end found back buffer and stencil buffers multi sample types }//end found a match }//end all sample types //we neaver set a type so set one *pQualityLevels = 0; *type = D3DMULTISAMPLE_NONE;}//end GetMultiSampleSupported////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////how to use it

I'm not sure about MDX, but in un-managed you want to turn on texture filtering (It defaults to nearest neighbour). The following will enable trilinear filtering for instance:
pDevice->SetSamplerState(0, D3DSAMP_MAGFILTER, D3DTEXF_LINEAR);pDevice->SetSamplerState(0, D3DSAMP_MINFILTER, D3DTEXF_LINEAR);pDevice->SetSamplerState(0, D3DSAMP_MIPFILTER, D3DTEXF_LINEAR);This topic is closed to new replies.
