I am wondering if there is a way to create a "pixelated" effect in openGL with textures.
I have been using vades v001.pixelate.jxs shader (what a great collection) on my tower (mac quadCore dual Intel), however on my laptop (Mac 1.67GHz PowerPC G4 / Radeon 9700 video card) the shader does not work. Most of vades shaders work on my laptop, although some of them do not (all of them work on my desktop).
I would like to process the effect in openGL, what is the best way to do this?
Below is a patch if you care to see an example.
