[osg-users] mutipass shaders

Hi, everyone: Is there anyone here has used mutipass shaders in osg? Which of the osg examples has been talking about this? Or is there any else examples about this? thanks ___ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.

[osg-users] using OSG as a plugin with dlopen() and dlclose()

Hi, We're trying to use OSG within a dynamically loaded plugin in our code. Whenever we call dlclose() on our plugin, however, shortly after main() returns we segfault. I was wondering if anyone who's worked with OSG has heard of this kind of problem before? I've attached an example of wha

If you want to move the selected object around on a plane (which sounds like what you want to do), then you can do a simple ray/plane intersection test and get the world coordinates from that. For example, if your object is at [5 3 8] and you want to move it on the z-plane, then you just use the
