Geometry shaders

OpenGL
1

I am interested in trying out some of the new features of my 8800, including geometry shaders. I can’t find much info on how these work and what they can be used for. Can anyone point out some good tutorials and demos, just so I can get an idea of what is possible? Thanks!

For the works, there’s the spec:
http://opengl.org/registry/specs/EXT/geometry_shader4.txt

And there’s a fine list of use cases here:

I hope this proves fruitful for you :slight_smile:

I was hoping to find a terrain demo or something that would totally blow my mind.

I guess one consequence of getting better at this stuff is I have fewer and fewer of those moments where I am like “holy crap!” :stuck_out_tongue:

Check out Nvidia's demos , i.e. transform feedback fractal.

And ATI's demos , i.e. global illumination.

then you’re getting better faster than I am. I’ve had my G80 for several months now and I still feel like I’ve barely scratched the surface :stuck_out_tongue:

Well, there are a lot of cool tech demos, but there’s a big difference between a tech demo and a technique that can actually be used in a shipping game.

Thanks for the links.
