Title: GLSL Programming?
Post by: matija123 on November 04, 2013, 02:37:33 pm
Hey guy's, soo i watched some effects on heroku.glsl.com and i really liked it, but how did they programmed those effects.
What is GLSL?
Basics?
How to start?
I am really interested, and im looking forward for some help and programming  O0

I hope in future it may be possible to fix a couple of problems that affect 0.8.8 implementation of GLSL shaders when the shader is run with GLSL support disabled or with errors...

Hi Matija! did you download the demo map? try changing one of the glsl programs in there (just change the numbers/parameters a little and see what changes in the map). '/r_ext_vertex_shaders 1' to enable glsl (you probably know that but for anyone else who might be reading and not aware of it)..

'/r_ext_vertex_shaders 1' to enable glsl
/r_ext_vertex_shader, without the final "s"...  ;)
