Hello there, are you the famous manguliok from the vegaprime forum?? I hope so... to the business, I'm new to the OSG, as I understood from your question I'm in the same need, but I just can't understand Robert tips. I set up my entire camera as the frustrum, but where do I select the triangle I wish to know if it's on screen now. For my case, the triangle I look after is a part of a big mesh that is always on screen (it's a huge mesh used as a terrain). ????
