Implement a post-processing Gaussian blur render pass.
~vtkGaussianBlurPass() override
Destructor.
void ReleaseGraphicsResources(vtkWindow *w) override
Release graphics resources and ask components to release their own resources.
static vtkGaussianBlurPass * New()
void Render(const vtkRenderState *s) override
Perform rendering according to a render state s.
vtkOpenGLFramebufferObject * FrameBufferObject
Graphics resources.
vtkTextureObject * Pass2
vtkTextureObject * Pass1
vtkOpenGLHelper * BlurProgram
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
vtkGaussianBlurPass()
Default constructor.
Convenient class for post-processing passes.
a simple class to control print indentation
