HI Cyrille and others.
I modified the abstraction to make opening the two files easier. It uses file/parentfolder from the PdMtlAbstractions. (try it !! It answers your question)
great, thanks.
For the C programming and such, I just meant that it is nice if we can tend to make Pd easier to use for people that are not that much used to advanced programming. A good documentation and a nice structure helps a lot...
i strongly aggre. and from my experience, a good documentation is 80% of the job.

Eh Jack ! Very nice examples, yes. Cyrille, do you think that one should understand C programming in order to use Pd? I don't.
i don't see your point here. glsl programming is not very diferent from C. So, understanding C is good for learning glsl. but you don't nead glsl in order to use pd. you just need glsl if you want to do very heavy pixel processing at 50fps / 1024x768 without using any CPU time by exemple.
Of course, its low-level orientation makes it perfect for someone to learn lower level stuff.
Anyways, I added an abstraction for shaders in the PdMtlAbstractions. See https://devel.goto10.org/pdmtl/browser/trunk/pdmtl/gems
cut / paste the help file is (for me) easier to use, as i usually put the shader in in the same directory as my patch, so i don't nead to provide the full path for the shader. (and the patch could run on other computer without changing all path). is there a solution for an abstraction to know the directory of it's parent patch?

Yep, very interesting example ! You can "boost" Gem with glsl object. Is there workshop in Paris about that Cyrille ? I think, that it would be interesting to do.

Wow, these are some nice examples, these should be included in the "examples" section of Pd-extended.
well, i think i should clean up some code and check licence for the
shader
i did not write. where should i put them in order to include them in pd-extended?
