Generate mipmap sublevels.
VOID GenerateMipSubLevels();
None.
No return value.
An application can generate mipmap sublevels at any time by calling IDirect3DBaseTexture9::GenerateMipSubLevels. To have mipmap sublevels generated automatically at texture creation time (see Automatic Generation of Mipmaps), specify D3DUSAGE_AUTOGENMIPMAP during IDirect3DDevice9::CreateTexture, IDirect3DDevice9::CreateCubeTexture, and IDirect3DDevice9::CreateVolumeTexture. For more information about usage constants, see D3DUSAGE.
