Thanks, Mike -- I had not tried that model yet; very cool. It shows that osgParticle Drawables recompute their bounding boxes on the fly.
You can also bring up the cow, pan so it's completely outside the frustum, then rotate around -- the near/far planes instantly readjust when the cow comes back into the view volume. Kind of neat. Robert suggested adding some keyboard controls to osgthirdpersonview, such as switching between the different auto compute modes, changing the FOV, etc. If anyone wants to do this, please go ahead. -Paul > > Hi Paul, > > You're probably aware of this, but I happened across a very > useful demonstration using your osgthirdpersonview with the > cessnafire.osg model.
