|
* @brief Render pass calling the FXAA filter
|
||
|
|
*
|
||
|
|
* vtkOpenGLFXAAPass is an image post processing render pass. It is a fast anti aliasing
|
||
|
|
* filter.
|
||
|
|
*
|
||
|
|
* This pass usually takes the camera pass as its delegate pass.
|
||
|
|
*
|
||
|
|
* @note Currently, this pass wraps the existing FXAA implementation. It copies the pixels
|
||
|
|
* from the framebuffer to a texture. A better approach would be to use the usual render pass
|
||
|
|
* workflow to create a framebuffer drawing directly on the texture.

||
