// .NAME vtkCuller - a superclass for prop cullers
|
|
// .SECTION Description
|
|
// A culler has a cull method called by the vtkRenderer. The cull
|
|
// method is called before any rendering is performed,
|
|
// and it allows the culler to do some processing on the props and
|
|
// to modify their AllocatedRenderTime and re-order them in the prop list.
