Public Function GetNumVoxels ( 
	realSize As SbVec3i32,
	subsamplingLevel As SbVec3i32
) As SbVec3i32

public:
SbVec3i32 GetNumVoxels(
	SbVec3i32 realSize, 
	SbVec3i32 subsamplingLevel
)

member GetNumVoxels : 
        realSize : SbVec3i32 * 
        subsamplingLevel : SbVec3i32 -> SbVec3i32 

Parameters

realSize

Type: OIV.InventorSbVec3i32

subsamplingLevel

Type: OIV.InventorSbVec3i32

Return Value

Returns the size of the brick the reader must use, based on subsamplingLevel and realSize of the brick. If the subsampling level is greater than 0 on an axis, the corresponding size is computed as follows:

realSize is divided by 2** subsamplingLevel

brickSize is the next greater power of 2

For example, if subsamplingLevel[0]=1 and realSize[0]=21, then the returned readerSize[0]=16.

If subsamplingLevel is 0, the corresponding size is the realSize.
