This is great news. Im super busy trying to finish up some things for
another project, but come mid august I should have time to port the
shaders im working on to PD, and now that Hans is back in NYC I can
get him to help ;)
Thanks Chris for taking the time to look into this. I havent had a
chance to ask the C74 guys anything, but at this point I guess I dont
need to.
Much appreciated!

Great! Which platform and hardware are you testing on? I should
have
mentioned that I've only tested on OSX/Nvidia here.

CVS is updated. Hopefully this won't break anyone's compiles.
The attached files are a test patch and the shaders. I will be
out of
town for a few days and not able to work on this again until next
week.

I have multitexturing working with GLSL. While I upload the
changes
to CVS I can explain how it works.
GLSL shaders cannot directly talk to hardware like ARB ones
can. The
application side code has to tell the shader which hardware
texture
unit to use. Obviously when I compile GEM there is no way in
hell to
know what the shader variables are going to be named, so another
method to tell the shader which unit to use needs to be in place.
One solution is to hardcode the names of the sampler variables,
but
that is kind of a hack. The one I put in place uses a message
to the
glsl_program object with the name of the sampler and the texture
unit
to use.
How to use:
1) create gemwin and turn on rendering
2) load shader
3) send a [mySamplerName $1( message to glsl_program
4) load two movies or images
5) set one of the pix_texture units to upload to the same
texture unit
you told the shader to use with a [texunit $1( message
This change should be in CVS soon. I will post an example patch
in a
bit.
