OpenGL rendering window.
Avergae frames to simulate motion blur.
void ReleaseGraphicsResources(vtkWindow *w) override
Release graphics resources and ask components to release their own resources.
window superclass for vtkRenderWindow
Definition: vtkWindow.h:34
Context in which a vtkRenderPass will render.
a simple class to control print indentation
Definition: vtkIndent.h:33
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
Internal class which encapsulates OpenGL FramebufferObject.
abstracts an OpenGL texture object.
virtual void Render(const vtkRenderState *s)=0
Perform rendering according to a render state s.
static vtkObject * New()
Create an object with Debug turned off, modified time initialized to zero, and reference counting on...
Convenient class for post-processing passes.
