Getting models into your application will likely be one of the biggest challenges. There is a good chance the models will contain parametric data, if so you'll need to consider how to tessellate the parametric surfaces into triangle meshes so that they can be rendered by the graphics hardware. You can tessellate data on the CPU and this in the past was traditional way to do it, but these days the GPU should be able to take on some of this work. This area is a big topic. As for performance optimization, the OSG has lots of support for various features for getting the best performance out of scene graph, but in the end it's how you construct your scene graph that will determine how well it will perform. Performance optimization is another huge topic that I can't sumerise in book let alone a single email so I would suggest breaking the task down it smaller elements that focus on your specific needs and ask specific questions here in the community and we'll have a better chance of answering them. So take a step back, tell us what type of data you have to work with, what number of objects is likely to be, how complex in geometry are these objects likely to be, do you have meshes or parametric surfaces etc. Robert. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
