I think all the OP's questions have been dealt with already, but it's probably worth pointing out that this is not 'my' shader, it's based on something BB posted a long time ago. If the search function here produced meaningful results I'd post the link to that.

Also note that displacement value = height of grass in whatever units you're working in. I always work in metres. The value in my post in the original thread translates to exactly 2 inches, so I'm guessing that that was what BB originally had in there.

You can apply the shader to anything you want, but I used a Cloth Plane (Hi res square) for the examples I showed. If you have Poser 8, try the shader on round or square high res groundplanes - it works a treat.
