The OCRenderAction (OcclusionTest / ExperimentalTest / OCRenderAction.cpp) performs front-to-back rendering with synchronous occlusion queries. > > Dirk: Are there any predefined front-to-back traversals in > > 1.4?

Could you send that to > me and Moritz (and Christoph might be interested, too)? Uhm... the code is really horrible and I think, it is only useful with some comments. I can send you the code, but if you give me some time, I will do a cleanup. The actual traversal scheme uses the screen space information of the nodes' bounding boxes to arrange them in multiple occlusion queries. This leads to a more complex traversal of the scene graph but with lower latency of the occlusion queries.
