I'm not an OpenGL expert, but I believe the frustum is used for determining whether an object can be seen from the current camera view (e.g. it's not behind the camera or off to the sides). I don't think the frustum controls the camera position or rotation, though. For that, I think you want to look at the LLCoordFrame class (llmath/llcoordframe.cpp), which is inherited by the llCamera class. Hope that helps. :-) - Jacek _______________________________________________ Policies and (un)subscribe information available here: http://wiki.secondlife.com/wiki/OpenSource-Dev Please read the policies before posting to keep unmoderated posting privileges
