Thats not quite true Sketchup files can contain physics, you can find many files in the wharehouse with physics

I concur with Jan on this. If the COLLADA file originated as a SketchUp file, then clearly it doesn't contain any physics information. Build OSG with the COLLADA plugin, load the file in OSG, then use the osgBullet tools to create the collision shapes and rigid bodies under programmatic control. osgBullet contains example programs that show many different ways for how to do this. -- -Paul Martz Skew Matrix Software http://www.skew-matrix.com/ _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
