Oh, my mistake. Sorry I misunderstood.

But there's a significant amount of code, both in OSG and external projects that use OSG, that dynamic_cast Drawables to Geometry objects, and if the cast fails, the code does nothing. So, you've been warned. :-) I think ShapeDrawables are an excellent illustration of how to derive a custom Drawable in OSG. And, as this thread shows, they also demonstrate how custom Drawables have their limitations. It'd be trivial to implement sphere, cone, box, and cylinder using the Geometry class. -Paul _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
