hi,
this is related to an old thread between cyrille and chris http://lists.puredata.info/pipermail/gem-dev/2006-09/002240.html. I tried this on my macbook pro (ATI Mobility Radeon X1600) and the printout says "[glsl_program]: vertex shader running in software" which, according to the discussion was not the case earlier.
to get noise textures working on the hardware, it is not possible to load a 3d noise texture to the shader, as of yet?
marius.
