Re: [osg-users] [osgPPU] CubeMap reflection
Hi Art, I agree, I couldn't get it working. The only way I found was to let osgPPU process my computation until the normals and then use it as output texture on the geometry that has the reflection and refraction shader like one do in the example osgvertexprogram. Vincent Le 05/10/2010 15:18, Art Tevs a écrit : Hi Vincent, take a look into the osgreflection example shipped with OSG. One of this examples shows the cubemap reflection implementation. You cannot achieve reflection with osgPPU, since it does not know anything about your cameras or other stuff. The cubemap exampel showed with osgPPU is just to show that you can also use CubeMap textures as input/output with osgPPU.

Re: [osg-users] Vertex Buffer Objects and Transform Feedback
Hi, I could read this post but didn't see any answer of it. Does someone have a working implementation of that ? Thanks, Vincent ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Rendering to texture 1 from texture 0 and switching the textures
Hi, what do you mean with osgPPU ?

I can't be 100% sure, but this sounds like a job for osgPPU. :) If I'm not mistaken, this is exactly the kind of thing it purports to do (and more). Could someone help me ?
