Detailed Description

Abstract class for a volume mapper.

Date:

2000/12/10 20:08:58

Revision:

1.46

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.

Member Function Documentation

virtual const char* vtkVolumeMapper::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkAbstractMapper3D. Reimplemented in vtkOpenGLVolumeProVG500Mapper, vtkVolumeProMapper, vtkVolumeProVG500Mapper, vtkMesaVolumeTextureMapper2D, vtkOpenGLVolumeTextureMapper2D, vtkVolumeRayCastMapper, vtkVolumeTextureMapper, and vtkVolumeTextureMapper2D.

int vtkVolumeMapper::IsTypeOf (  const char *    type )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkAbstractMapper3D. Reimplemented in vtkOpenGLVolumeProVG500Mapper, vtkVolumeProMapper, vtkVolumeProVG500Mapper, vtkMesaVolumeTextureMapper2D, vtkOpenGLVolumeTextureMapper2D, vtkVolumeRayCastMapper, vtkVolumeTextureMapper, and vtkVolumeTextureMapper2D.

virtual int vtkVolumeMapper::IsA (  const char *    type )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkAbstractMapper3D. Reimplemented in vtkOpenGLVolumeProVG500Mapper, vtkVolumeProMapper, vtkVolumeProVG500Mapper, vtkMesaVolumeTextureMapper2D, vtkOpenGLVolumeTextureMapper2D, vtkVolumeRayCastMapper, vtkVolumeTextureMapper, and vtkVolumeTextureMapper2D.

vtkVolumeMapper* vtkVolumeMapper::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkAbstractMapper3D. Reimplemented in vtkOpenGLVolumeProVG500Mapper, vtkVolumeProMapper, vtkVolumeProVG500Mapper, vtkMesaVolumeTextureMapper2D, vtkOpenGLVolumeTextureMapper2D, vtkVolumeRayCastMapper, vtkVolumeTextureMapper, and vtkVolumeTextureMapper2D.

void vtkVolumeMapper::PrintSelf (  ostream &    os, vtkIndent    index )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkAbstractMapper3D. Reimplemented in vtkVolumeProMapper, vtkMesaVolumeTextureMapper2D, vtkOpenGLVolumeTextureMapper2D, vtkVolumeRayCastMapper, vtkVolumeTextureMapper, and vtkVolumeTextureMapper2D.

virtual void vtkVolumeMapper::Update (  void    )  [virtual]

Update the volume rendering pipeline by updating the scalar input Reimplemented from vtkAbstractMapper3D. Reimplemented in vtkVolumeTextureMapper.

void vtkVolumeMapper::SetInput (  vtkImageData *    )

Set/Get the input data

vtkImageData* vtkVolumeMapper::GetInput (    )

virtual void vtkVolumeMapper::SetCropping (  int    )  [virtual]

Turn On/Off orthogonal cropping. (Clipping planes are perpendicular to the coordinate axes.)

virtual int vtkVolumeMapper::GetCropping (    )  [virtual]

virtual void vtkVolumeMapper::CroppingOn (    )  [virtual]

virtual void vtkVolumeMapper::CroppingOff (    )  [virtual]

virtual void vtkVolumeMapper::SetCroppingRegionPlanes (  float   , float   , float   , float   , float   , float    )  [virtual]

Set/Get the Cropping Region Planes ( xmin, xmax, ymin, ymax, zmin, zmax )

virtual void vtkVolumeMapper::SetCroppingRegionPlanes (  float   [6] )  [virtual]

virtual float* vtkVolumeMapper::GetCroppingRegionPlanes (    )  [virtual]

virtual void vtkVolumeMapper::GetCroppingRegionPlanes (  float    data[6] )  [virtual]

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. The regions start from the one containing voxel (0,0,0), moving along the x axis fastest, the y axis next, and the z axis slowest. 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.
