Asking a similar question recently on this list I got told that a lot is
possible using shaders.

thought so ;-)

See if you have a folder named 10.glsl on your
OS somewhere that could hold Gem examples for shaders.

that's what i did. unfortunately i can't get any shader-related patch to work. 
i tried them all in the 10.glsl folder. always ends up in

[glsl_vertex]: error reading file
[glsl_fragment]: error reading file

in the console.

the graphic-card is NVIDIA GeForce GT 630M, WIN7/64bit.
is it the card that's wrong ?
no, I did most of the glsl example using this GPU.


can you open the shader file on a windows text editor?
I never had this kind of error. After 15 years without windows, it still 
surprise me.



GEM-related stuff seems to be pretty scattered on the web, those who are using 
it at all seem to do so quite privately.

at least i wasn't able to find something like a patch repository or a dedicated 
discussion forum that could hopefully explain the GEM world a little deeper. 
the help files and tutorials are sparse and a little dated (however useful to 
get me starting !)

any further info regarding the use of shaders in GEM is highly appreciated !

How to use a shader with GEM is explain in the examples, and it is usually 
straightforward.

How to develop shader is not specific to GEM, and you'll file billions of 
website dedicated to glsl.

cheers

happy easter !
