I'm trying to use the GLSL noise1 function, but no matter what I do, it will return me a value of 0. Is it not implemented yet or what?

I'm using a 6800 ultra with the driver 71.40

Thanks

Right, not implemented.

Check these instead:

Cool that's great, exactly what I needed. Thanks for the links Relic, and of course to StefanG for posting is work. I have to understand it now...

To *understand* my code, you might be helped by this:

Just for you information, nVidia claimed in the following document that they don't support noise1/2/3/4 currently:
