|
||
|
|
*
|
||
|
|
* 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.
