 I innocently started a grass competition several months ago by posting
an image of grass created using a HF approach. This started a small
flurry of posts by others showing off their techniques. My HF approach
has the bennifit of using the least amount of memery than any other
proceedural process but is more suited for long shots. The method you
described, with and without bent blades, is better suitable for close up
work and several examples have been posted in the scene files groups
on this server.
