Detailed Description

Region representing a 3D box.

Voxels are ordered line by line, slice by slice. 1st voxel is in corner (minX, minY, minZ). 2nd voxel is in (minX+1, minY, minZ). Last voxel is in (maxX, maxY, maxZ)

Constructor & Destructor Documentation

SubVolumeRegion()

SbImageDataAccessor::SubVolumeRegion::SubVolumeRegion

(

const SbBox3i32 &

subVolume

)

Constructor.

Member Function Documentation

getExtent()

virtual SbBox4i32 SbImageDataAccessor::SubVolumeRegion::getExtent ( ) const

inlinevirtual

Returns extent of region.

As this region is a 3D space, the last coordinates of the extent are always 0. The 3 first coordinates correspond to the SbBox3i32 given in the constructor.

Implements SbImageDataAccessor::Region.

Definition at line 128 of file SbImageDataAccessor.h.

getNumVoxel()

virtual uint64_t SbImageDataAccessor::SubVolumeRegion::getNumVoxel ( ) const

virtual

Returns number of voxels contained in the region.

Implements SbImageDataAccessor::Region.

getPosition()

virtual SbVec4i32 SbImageDataAccessor::SubVolumeRegion::getPosition ( uint64_t  i ) const

virtual

Returns position of the ith voxel of the region.

ie. getPosition(0) returns the lower left corner of box given in constructor.

Throws out of range exception if i >= getNumVoxel()

Implements SbImageDataAccessor::Region.

getSize()

virtual SbVec4i32 SbImageDataAccessor::SubVolumeRegion::getSize ( ) const

inlinevirtual

Returns the dimensions of the region.

As this region represent a 3D space, getDimension()[3] is always 1. getDimension()[0], [1] and [2] correspond to size of SbBox3i32 given in constructor.

Implements SbImageDataAccessor::Region.
