Hi all, I am constructing an urban model to visualize a quarter entire, am using data base spatial to get the information of the streets, squaresÂ… and each entity has an object 3D for its representation. As the object number is great, I only load in my graph of scene those objects that are near of the camera. I used the osgimpostor example to make my manipulator of the camera, and each movement of the camera I consult in the data base the objects that are near of this position and the loaded.
Here my problem appears, to each change in the position of the camera I all erase the content of mine of the scene graph and later I place all again the objects, and believe that is this the reason of mine framerate to fall very. I would like to know as I make to cross the scene graph to verify which nodes must be removed and which must be inserted, not to be necessary to remove all and again place them to each movement of the camera. Thanks, Ronald S.Serrao, Brasil. _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
