Microsoft DirectX 8.0 (Visual Basic) |
Filters mipmap levels of a volume texture.
object.FilterVolumeTexture( _ VolumeTexture As Direct3DVolume8, _ Palette As Any, _ SrcLevel As Long, _ MipFilter As Long)
If the method fails, an error is raised and Err.Number can be set to D3DERR_INVALIDCALL.
For information on trapping errors, see the Microsoft Visual Basic® Error Handling topic.
For more information on PALETTEENTRY see the Microsoft Platform Software Development Kit (SDK). Note that as of Microsoft DirectX 8.0, the peFlags member of the PALETTEENTRY structure does not work the way it is documented in the Platform SDK. The peFlags member is now the alpha channel for 8-bit palletized formats.
Box-filter is recursively applied to each texture level to generate the next texture level.
