Hi all. I have a strange behavior when I let OSG update the near and far clipping planes during drawing. When I use a perspective projection, and I move the camera inside the model (I mean, inside the global
bounding sphere of the model), the near clipping plane is placed very near to the camera, so to clip as few objects as possible. I like this behavior, and I would like to use it also for Orthogonal projections. But in that case, when I move the camera into the model, the near clipping plane becomes negative, so the viewing volume includes always the whole model. And I don't like this now. Is this the right behavior, or did I miss something/make some mistake? If this is the way it works for orthogonal projections, is there a way to make it work like perspective one? Thanks in advance.
