Geometry shaders

[Leadwerks]

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 :-)

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!" :p

Check out Nvidia\'s demos (http://developer.download.nvidia.com/SDK/10/opengl/samples.html) , i.e. transform feedback fractal.

And ATI\'s demos (http://ati.amd.com/developer/SDK/Samples_Documents.html#d3d10) , i.e. global illumination.

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!"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 :p

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.
