I used the the gears.rb as the basis for a OpenGL programmable shader (i.e.
GLSL) version of the gears program. The intro to it and download can be
found through here:

The shaders are nice. Is OpenGL able to use shaders ? Or you made it to
use shaders your own way ?

I have a bug. I installed required librairies, but there is still a
problem.
http://gemcutter.org/gems/ffi-opengl

Ruby-processing seems to be very cool !
And powerfull.

I'm looking at the "rp5 app" function to create windows executables (I'm
working on windows).
The web version seems to be a good idea, but the programs weight at less
10 Mo.
And my firefox bugs when I try to load one.


I think I will use ruby-processing if I succeed to release windows
executables with it.

I remember I have had this kind of problems, trying to use OpenGL.
Maybe I don't have the right version of one library, or I don't install
a SDK.

Here's my bug :


require "ffi-opengl"
