helper class for a ray cast image
a simple class to control print indentation
Definition: vtkIndent.h:113
abstract base class for most VTK objects
Definition: vtkObject.h:82
helper class that draws the image to the screen
~vtkRayCastImageDisplayHelper() override
virtual void ReleaseGraphicsResources(vtkWindow *)
Derived class should implement this if needed.
virtual void RenderTexture(vtkVolume *vol, vtkRenderer *ren, int imageMemorySize[2], int imageViewportSize[2], int imageInUseSize[2], int imageOrigin[2], float requestedDepth, unsigned short *image)=0
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
static vtkRayCastImageDisplayHelper * New()

vtkTypeBool PreMultipliedColors
Have the colors already been multiplied by alpha?
