So I have a big city database that I built in Creator with lots of external models loaded under transform nodes. I assumed that Optimizer could flatten this out for me with FLATTEN_STATIC_TRANSFORMS. Unfortunately, I only end up flattening 35 out of 911 transforms.
Tracing through the code, I find that line 804 of Optimizer.cpp is where things go bad for me: if (_firstMatrix!=matrix) _moreThanOneMatrixRequired=true; This line rejects most of my flattening because later on _moreThanOneMatrixRequired seems to be used to decide whether or not to flatten. If I comment this line out, then all but the first instance of each model disappears from my scene. Understanding all the logic in Optimizer.cpp could take me a long time. Is there some fundamental reason why having more than one matrix makes it impossible to flatten a model, or is this just incomplete code that I could extend to give me a more thorough flattening? Any tips on how to try and extend it would be great too.... -- Terry Welsh - mogumbo 'at' gmail.com www.reallyslick.com | www.mogumbo.com _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
