OpenGL rendering window.
void ReleaseGraphicsResources(vtkWindow *w) override
Release graphics resources and ask components to release their own resources.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
Convenient class for post-processing passes.
window superclass for vtkRenderWindow

Context in which a vtkRenderPass will render.
a simple class to control print indentation
Definition: vtkIndent.h:33
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.
