Remco,

Great Grass!

A couple of ideas to get rid of the lines/regularity. First, declare several
different patches and then use them randomly. Create several patches that
are only half as dense as you require, then when you tile them, overlap by
50%. Again choosing random pairs will get rid of the pattern. Finally, if
you declare your patches as being only 25% as dense as you want, then
overlap by 75 % and rotate them around the vertical axis a random amount,
the edges prety much disappear.

Good luck on this, I have been playing with this for a year or so off and
on. The largest "field" I have done is a kilometre square. This was a field
of wheat with plants spaced 10 cms apart and 8 - 10 blades per plant. That
is a LOT of triangles.

Regards
Gordon
