Hello everyone. Here's an idea built from previous attempts (not all my 
own) at making plant and tree life using height fields. I'd like some 
feedback if possible (suggestions, tales of personal attempts, etc.).

Two HFs are used in this image: one for the rocks and one for the trees. 
The trees use the same topology that was used for the rocks (minus a 
feature, plus a feature), with a special angle-dependent texture to 
give them fuzzy edges. Manipulation of surface normal accuracy was also 
needed for this purpose.

There are many things to improve upon, such as making the trees more 
detailed and developing new tree types. I believe the technique has 
great potential. What do you think?

P.S. Oh yeah, it took very little time to render.... something like 
under four minutes if I'm remembering correctly.
