Re: [PD] FW: GEM noobie: I don't understand this glsl thing... but I need it!

[Patrice Colet]

Thank you for sharing this! Particulary the links at the end of the page, the 
shaders proposed at https://www.shadertoy.com
are easy to transpose for Gem, attached is an experiment with the fireball 
shader.

Hello,

oops, initialy not replied to the list ...

We have a modest wiki page in french about Pd vs glsl, some ressources
there as well http://wiki.labomedia.org/index.php/Pure_Data_vs_OpenGL

Re: [PD] FW: GEM noobie: I don't understand this glsl thing... but I need it!

[Cyrille Henry]

the glsl exemples are in a specific folder in gem/exemple.
it's not very documented, but you'll have some basic shader.
it's a good place to start.

Hi, and thank you for your answers,

I know about extended view, I 've donwloaded it and used to build my design. 
The idea for me is now to get a better understanding of the glsl chain, because 
it seems to be the place where all the magic happens. I thought I could find 
more examples of glsl objects implementations in pd, and some written code that 
I could try to hack... any help appreciated.

[PD] FW: GEM noobie: I don't understand this glsl thing... but I need it!

[David Schaffer]

Hi, and thank you for your answers, 


  
I know about extended view, I 've donwloaded it and used to build my design. 
The idea for me is now to get a better understanding of the glsl chain, because 
it seems to be the place where all the magic happens. I thought I could find 
more examples of glsl objects implementations in pd, and some written code that 
I could try to hack... any help appreciated.
