That's easy. In fact I implemented an image_map dependent way to define or
exclude areas of vegetation. But I can imagine several ways to exclude some
areas. The challenge lies in the borders - if you look carefully, grass
becomes sometimes smaller and differently orented near the borderline.

Because it is less boring I use an animation for the iterations. I write the
values in an include file which is read back for each iteration step.
Of course its all done within Povray.
