Hi Fred and Sergey, Thanks for the great information. I viewed the Rembrandt wiki page and love the design of the effect files. I will consider merge some of the concepts of Rembrandt if possible, along with current osgPPU and osgPostEffects projects, to try designing an extensible system for all. I would like to submit some of my initial code here for all of you to review and see if it could fit everyone's taste. I hope I could have done that in the following week.
Thanks, Wang Rui 2012/6/22 Frederic Bouvier <[email protected]> > I was going to raise that point.
