[osg-users] another shader question

[Marcus Fritzen]

Hello everybody,

I asked the question before in the old list. How can I realize more than 
one renderpass? What I want to have is two programs with each one 
fragment shader.
In the first one I want to compute some things where I need 
neighbourinformation of pixels. In the second one I want to compute 
things on the modified first texture. So perhaps someone can tell me in 
short, what I need and what I have to do.
Thanks,
