Hello, all.

Here's my stab at grass on a heightfield using trace(). The grass is made up
of 300,000 copies of one blade mesh, randomly rotated, resized, coloured and
finished.  Took just over an hour to render in MegaPOV 0.7 on my shamefully
fast PC (1.3Ghz), and most of that was parsing time.

It looks OK-ish, but the texture is bobbins and there's no sense of scale in
this pic anyway.

Bye,
Alan.
