## Detailed Description

Abstract class for a volume mapper.

Date:
  2003/03/07 16:15:52

Revision:
  1.59.12.1

vtkVolumeMapper is the abstract definition of a volume mapper. Several basic types of volume mappers are supported. There are ray casters, which produce an image that must be merged with geometry, there are hardware methods that blend with geometry, and some combinations of these.

virtual void vtkVolumeMapper::SetIndependentComponents | ( | int |  | ) | `[virtual]`

Does the data have independent components, or do some define color only? If IndependentComponents is On (the default) then each component will be independently passed through a lookup table to determine RGBA, shaded, and then combined with the other components using the ComponentBlendMode. Some volume Mappers can handle 1 to 4 component unsigned char or unsigned short data (see each mapper header file to determine functionality). If IndependentComponents is Off, then you must have either 2 or 4 componenet data. For 2 component data, the first is passed through the first color tranfser function and the second component is passed through the first opacity transfer function. Normals will be generated off of the second component. For 4 component data, the first three will directly represent RGB (no lookup table). The fourth component will be passed through the first scalar opacity transfer function for opacity. Normals will be generated from the fourth component.

virtual void vtkVolumeMapper::SetCroppingRegionFlags | ( | int |  | ) | `[virtual]`

Set the flags for the cropping regions. The clipping planes divide the volume into 27 regions - there is one bit for each region.

These are represented from the lowest bit to bit number 27 in the integer containing the flags. There are several convenience functions to set some common configurations - subvolume (the default), fence (between any of the clip plane pairs), inverted fence, cross (between any two of the clip plane pairs) and inverted cross.
