Thanks for the example code. When I bring it up, I get cull ~5ms, and draw ~15ms. I then use the middle mouse button to drag all the billboards off the screen, and I get cull ~0.1ms, and draw ~0.3ms. So, obviously, frustum culling is working.
However, performance is a cliff that only drops off when all billboards are offscreen. This tells me something is wrong in the organization of your scene graph. There is already quite a bit of discussion regarding that on this thread. When the data in your scene graph is spatially organized, you should see cull/draw times ramp down as the amount of visible data decreases. -Paul _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
