Detailed Description

a ray function for compositing.

Date:

2000/12/10 20:08:59

Revision:

1.20

vtkVolumeRayCastCompositeFunction is a ray function that can be used within a vtkVolumeRayCastMapper. This function performs compositing along the ray according to the properties stored in the vtkVolumeProperty for the volume.

Member Function Documentation

vtkVolumeRayCastCompositeFunction* vtkVolumeRayCastCompositeFunction::New (    )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkObject.

virtual const char* vtkVolumeRayCastCompositeFunction::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 vtkVolumeRayCastFunction.

int vtkVolumeRayCastCompositeFunction::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 vtkVolumeRayCastFunction.

virtual int vtkVolumeRayCastCompositeFunction::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 vtkVolumeRayCastFunction.

vtkVolumeRayCastCompositeFunction* vtkVolumeRayCastCompositeFunction::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 vtkVolumeRayCastFunction.

void vtkVolumeRayCastCompositeFunction::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 vtkObject.

virtual void vtkVolumeRayCastCompositeFunction::SetCompositeMethod (  int    )  [virtual]

Set the CompositeMethod to either Classify First or Interpolate First

virtual int vtkVolumeRayCastCompositeFunction::GetCompositeMethod (    )  [virtual]

void vtkVolumeRayCastCompositeFunction::SetCompositeMethodToInterpolateFirst (    )  [inline]

Definition at line 77 of file vtkVolumeRayCastCompositeFunction.h.

void vtkVolumeRayCastCompositeFunction::SetCompositeMethodToClassifyFirst (    )  [inline]

Definition at line 79 of file vtkVolumeRayCastCompositeFunction.h.

const char* vtkVolumeRayCastCompositeFunction::GetCompositeMethodAsString (  void    )

void vtkVolumeRayCastCompositeFunction::CastRay (  VTKRayCastRayInfo *    rayInfo, VTKRayCastVolumeInfo *    volumeInfo )  [virtual]

Reimplemented from vtkVolumeRayCastFunction.

float vtkVolumeRayCastCompositeFunction::GetZeroOpacityThreshold (  vtkVolume *    vol )  [virtual]

Get the value below which all scalar values are considered to have 0 opacity. Reimplemented from vtkVolumeRayCastFunction.

void vtkVolumeRayCastCompositeFunction::operator= (  const vtkVolumeRayCastCompositeFunction &    )  [inline, protected]

Definition at line 94 of file vtkVolumeRayCastCompositeFunction.h.

void vtkVolumeRayCastCompositeFunction::SpecificFunctionInitialize (  vtkRenderer *    ren, vtkVolume *    vol, VTKRayCastVolumeInfo *    volumeInfo, vtkVolumeRayCastMapper *    mapper )  [protected, virtual]

This method gives the subclass a chance to do any special initialization that it may need to do BTX Reimplemented from vtkVolumeRayCastFunction.
