I should note that my needs are very similar to the ones described in this post:
http://forum.openscenegraph.org/viewtopic.php?t=5941&highlight=glreadpixels I adapted the sample code given at the end of that thread and found that while I was able to retrieve the correct pixel values, I also was getting the: warning: detected OpenGL error 'invalid operation' at after RenderBin::draw() warning after every frame, regardless of whether my rtt camera was set to post render or pre render. Unfortunately that thread ended 2.5 years ago without a full resolution to the outstanding questions. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=52096#52096 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
