Thanks, I totally agree when there's only one projector. But, if I have, let's say, P projectors and I want to apply textures as a blend from a max of N projectors while moving in the scene. Then, imagine we have M visible primitives from all cameras. The number of possible TexGenNodes will be superior to (please excuse me if it's confuse, I don't really know how to say it in proper english): binomial coefficient (P,N) * M Do you agree? ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=11823#11823 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
