To create an instance of class vtkVolumeRayCastFunction, simply invoke its constructor as follows
obj = vtkVolumeRayCastFunction
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.
