Cool! I've been experimenting with render-to-texture also, but it's still a bit sluggish. Can't wait for the lib =)

wow, amazing simon. looking forward to that library...

codeanticode.wordpress.com/2008/05/04/gltexture-renamed-to-glgraphics/

has allready some nice rtt FBO things and is a really easy way to implement shaders into Processing. Anyways For some reason the FBO rtt part does not work on my old Mac Book Pro.

Thank's guys :)

Lenny: Argh I should make some kind of user black list for guys like you ;)

moka: hehe that's funny i saw that two days ago... actually I used also as this guy (you?) the code of john g for starting my shader implementation... Look interesting! I will try that one of this day.

Anyway I have to say that this library is really not ready for any release right now, I think I'm going to put a link asap on my website for people interested but one important think for me is that all this code are a bit too much for advanced users (i mean pure opengl and glsl.. I'm actually just discovering all this) and i doesn't make sense to release a processing library if it's not thought to be the more accessible(and "beginner mind") possible...
So for now there won't be any real release with docs and good commented sources until I find some good way to make all that shit "easy"!

I guess the final result would be a lib that enable the use of easy realtime filters, and allow to FAKE a lot of stuffs that were only for postproduction... things like blur, motion blur, depth of field,sharpen, emboss, line detection, kaleidoscope stuffs, deformations, tilings, noise and actually exactly what you want to do if you're ready to mess with pixels one by one... opengl+glsl is something that look very powerfull and I'm lucky to have a cool "personal teacher" for discovering this...

Take it with you on next Sunday , I am sure we'll make some good use ;-)
