  I think that would be true. I have heard that some people have figured out
how to do realistic grasses with proceedural methods. I have not seen their
methods nor have I been successful my self at creating one. In the mean time
I go the image map route. Sigh ! As you probably noticed though I included
an example for the grass.gif image map using a height field. I think it looks
pretty good. I would like to find another image of grass that is not quite so
course to add to my collection. The grass.gif image is great for wild grasses
but looks a little to rough for lawns and golf courses.
