Cg + Processing... is it possible?
Oct 12th, 2008, 9:56pm  
Cg is a really nice alternative to GLSL. I noticed that jogl_cg.dll lives inside Processing's opengl library folder so I thought it might be possible, but Processing runs into trouble when trying to load the native library. I tried in the PDE and in Eclipse, but it doesn't work in either. Anyone know a hacky way to get it to work?

Code:

import processing.opengl.*;
import com.sun.opengl.cg.*;

CGcontext cg;

void setup()
{
  size(640,480,OPENGL);
  cg = CgGL.cgCreateContext();
}

void draw()
{
  background(0);
}

ac posted a class in this thread a while back.

I tried it out, but it was a few months ago so I don't remember what kind of results I got. CG is not something that comes with OpenGL "out of the box" so you need to run the toolkit installer from here

Thanks for the pointer to that thread. That looks like more than enough to get started. Also, yes, I needed to install Cg (duh!) and that got me past the native library linking problem.
