Hellor Robert, Every day I try to think a bit less, but it does not work for me... ;)
But seriously: OSG is a framework, which tries to fit several different use cases. And it is natural, that it will not fit perfect for every possible job. Thus I want to figure out, how I can use it in the best way for my purpose. I try to use shaders to project flat world geometry on a sphere to keep the scene graph simple. But cannot tune the culling stage to fit this situation (yet) and have to deal with a pretty crude workaround distorting the bounding boxes, which breaks the idea of keeping the flat world scene graph simple. I highly appreciate your help, but that does not imply, that I shall not have an own vision, of how to do certain things. Therefore I still think (being clever), that adapting the culling visitor would be a cleaner way. But unfortunately don't know, how to do it now, and since the OSG API is nearly undocumented, it is a hard way to go. All I want is a custom flat-world culler, set up of four clipping planes and a fitting AND/OR conjunction (for full-inside or warp-on-border cases). Is this that hard to do with OSG?
