// .NAME vtkCompressCompositer - Implements compressed tree based compositing.
|
|
//
|
|
// .SECTION Description
|
|
// vtkCompressCompositer operates in multiple processes. Each compositer has
|
|
// a render window. They use vtkMultiProcessController to communicate
|
|
// the color and depth buffer to process 0's render window.
|
|
// It will not handle transparency. Compositing is run length encoding
|
|
// of background pixels.
|
|
//
|
|
// SECTION See Also
|
|
// vtkCompositeManager.
