vtkVolumeRayCastFunction
Section: Visualization Toolkit Volume Rendering Classes
Usage
vtkVolumeRayCastFunction is a superclass for ray casting functions that
can be used within a vtkVolumeRayCastMapper. This includes for example,
vtkVolumeRayCastCompositeFunction, vtkVolumeRayCastMIPFunction, and
vtkVolumeRayCastIsosurfaceFunction.
To create an instance of class vtkVolumeRayCastFunction, simply
invoke its constructor as follows
obj = vtkVolumeRayCastFunction
Methods
The class vtkVolumeRayCastFunction has several methods that can be used.
They are listed below.
Note that the documentation is translated automatically from the VTK sources,
and may not be completely intelligible. When in doubt, consult the VTK website.
In the methods listed below, obj is an instance of the vtkVolumeRayCastFunction class.
-
string = obj.GetClassName ()
-
int = obj.IsA (string name)
-
vtkVolumeRayCastFunction = obj.NewInstance ()
-
vtkVolumeRayCastFunction = obj.SafeDownCast (vtkObject o)
-
float = obj.GetZeroOpacityThreshold (vtkVolume vol) - Get the value below which all scalar values are considered to
have 0 opacity.
