Detailed Description

Implement Screen Space Anti Aliasing pass.

Render to a larger image and then sample down

This pass expects an initialized depth buffer and color buffer. Initialized buffers means they have been cleared with farest z-value and background color/gradient/transparent color.

The delegate is used once.

Its delegate is usually set to a vtkCameraPass or to a post-processing pass.

Implementation:

As the filter is separable, it first blurs the image horizontally and then vertically. This reduces the number of texture samples taken.

void vtkSSAAPass::PrintSelf ( ostream &  os, vtkIndent  indent  )

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkRenderPass.

virtual void vtkSSAAPass::Render ( const vtkRenderState *  s )

virtual

Perform rendering according to a render state s.

Precondition

Implements vtkRenderPass.

void vtkSSAAPass::ReleaseGraphicsResources ( vtkWindow *  w )

virtual

Release graphics resources and ask components to release their own resources.

Precondition

w_exists: w!=0

Reimplemented from vtkRenderPass.

virtual vtkRenderPass* vtkSSAAPass::GetDelegatePass ( )

virtual

Delegate for rendering the image to be processed. If it is NULL, nothing will be rendered and a warning will be emitted. It is usually set to a vtkCameraPass or to a post-processing pass. Initial value is a NULL pointer.

virtual void vtkSSAAPass::SetDelegatePass ( vtkRenderPass *  delegatePass )

virtual

Delegate for rendering the image to be processed. If it is NULL, nothing will be rendered and a warning will be emitted. It is usually set to a vtkCameraPass or to a post-processing pass. Initial value is a NULL pointer.
