[osg-users] osgdepthpartition

The main problem with the osgdepthpartition example is the custom node isn't
thread sage, so the example forces the SingleThreaded model in Viewer.

A better solution for depth partition would be to use nested RTT cameras to
render back-to-front depth segments to textures, using the texture from the
prior pass to clear the framebuffer for the subsequent pass.

Hi all,
 In the depth partition example, the class DepthPartitionNode allows
changing the render order of the camera to PRE/NESTED but then the
calculation of the RenderBin leaves is incorrect.

 What is the logic for changing the cameras order?

 Besides I would like to know what are the disadvantages of using
DepthPartitionNode in ALL osg based application? Does is have problems with
HUDS or transparency?
