Thanx for your reply but I need to explain what I want.<неиI've seen stereomatch but I need to implement another thing.<неиI try to explain. So I try to make clouds rendering on GPU using cellular automata.<неиSo initial states are in texture1 and using FBO, attached to texture2 and pixel shader, I calculate states and write it to FBO texture2.<неиSo now for this steps initial steps are in texture2 and here is the main question how can I "disapply" texture2 from FBO and apply to texture1.<неиIn OSGPPU it was made by copying to additional texture so there is no any discomfort to programmer. But this trick need to use additional pass <неиIn my case copying 2048*2048 textures can take very long time. so I need dynamically change FBO - tex1,nextframe-tex2,nextframe-tex1,nextframe-tex2.<неиThe main problem that FBO statically applying when you create camera and in current OSG you can't dynamically change FBO attachment.<неиSo I'm newbie in OSG so if some explanations with code are welcome.<неиThanx in advance<неиBye<неи <неи<неи-----Original Message-----<неиFrom: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of J.P.
