Hi Robert, Going back to scene graph? have I to create 1) a scene with one geode for each geometry? or 2) only one geode containing all N geometry? My question is: Why do the two solutions seem to behave in the same way? Should the first way better fot frustum culling phase? I thought each

Hi Robert Sorry, I haven't much experience in computer graphics...can you explain me what you mean with GPU down in granularity? However I have tested the program in Windows XP 32 bit (precedent test was made in Vista 64 bit) and now I can use VBO and DL also for larger dataset (maybe the GPU

Hi Fabio, You say the problem fails.. but in what way? What hardware, OS, OSG versions are you working with? The OSG doesn't have a ply loader itself, is this your own loader. As for techniques for handling large models, I'd suggest switching off display lists, and then breaking the model down
