Hello..
I've been working a bit on my first IRTC entry, and allthou I haven't got anything
close
to what I wanted, (or anything useful at all, for that matter.) I have amnaged to
learn
quite a bit on texturing/Heightfields/math(*shudder*)

Well, then... What has he done, you ask... Except for creating some 30 trees and
inserting
in a scene, tried all possibilities for grass, tried almost every HF util.... Nothing
much...

ok, to buissness, I got this little thing working a while ago... I think I may add
some
more uniform rotations to it, but I'm rather satisfied with the result...

One thing. I don't intend to go for a compression >15% in JPEG, and.... a PNG actually
is
smaller in fileSize... 
But, since the global aversion on this format, here comes a few jpg's...
The basics is, a loop from 0->1, Y=Log(loop+0.5), X=Loop. And then another loop to
space
some more spheres in the inside. Nothing fancy..

Three of them are of objects in various size and amount, one is without any rotation
in y.

Have a look to my Particles Generator include file, you'll find some other shapes to
play with !
Although, nice results. Source ?

Thanks !
It is very-very-very long to parse and render on my little computer !
I have a question:
why is your Y_Trans (?) a log function ?

I wanted the smoothed curve on it, I didn't think the linear function
looked as good for my purpouse.
If you look, I think I left an option for it.
Hmm, try and change for a sine or something, moght be fun ;-)
