I think that sort-last rendering solve my problem. i understand that
in sort-last the scene is decomposed across all machines in cluster.
Then, there is a one computer which composes all decomposed parts into
the final image and displays it on its own monitor. But how to
implement sort-last in OpenSG? Any suggestions?
Thank You in advence
