vtkVolumeRayCastFunction is a superclass for ray casting functions that can be used within a vtkVolumeRayCastMapper. This includes for example, vtkVolumeRayCastCompositeFunction, vtkVolumeRayCastMIPFunction, and vtkVolumeRayCastIsosurfaceFunction.
|
Do the basic initialization. This includes saving the parameters passed in into local variables, as well as grabbing some useful info from the volume property and normal encoder. This initialize routine is called once per render. It also calls the SpecificFunctionInitialize of the subclass function. BTX |
|
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 vtkObject. Reimplemented in vtkVolumeRayCastCompositeFunction. |
|
Get the value below which all scalar values are considered to have 0 opacity. Implemented in vtkVolumeRayCastCompositeFunction. |
|
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 vtkObject. Reimplemented in vtkVolumeRayCastCompositeFunction. |
|
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 vtkObject. Reimplemented in vtkVolumeRayCastCompositeFunction. |
|
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 vtkObject. Reimplemented in vtkVolumeRayCastCompositeFunction. |
|
This method gives the subclass a chance to do any special initialization that it may need to do BTX Implemented in vtkVolumeRayCastCompositeFunction. |
