Foliage Study #1

Here is a foliage study.  Using multiple models and colors, I set the foliage in a "bubble" configuration, to where there are smaller and more instances on the edges, and larger and less instances in the middle (based over 3 different size ranges, each with its own 2:1 size range).  This is all mapped with a power fractal and with slope constraints.  I think it looks pretty realistic.

The trees were all made with Dryad.  Honestly, I am starting to really like that application!

Render time was horrendous!  It took nearly 80 hours @ 800x600, quality 0.8, AA 10.  This was over 4 cores, so a single core would have taken nearly 300 hours!  This is much too long and I can't wait for the next TG2 updates.

Part of this killer render time has to do with the surface effects on the leaves (which includes reflectivity/specularity, translucency, and even a hint of luminosity).  Additionally, I used an earlier version of the new fractal stack surface (the one to RULE them all).  I want to post a test render of this surface...its amazing, but HUGE and actually takes a while to render by itself!

This is really fantastic.  The colour shades and varieties is just incredible.

oh this is very nice....it does look realistic....

I love the variation...

great pops and very realistic colours !

The whole thing looks like a beautiful Ansel Adams photograph in color. 

Are you sure you aren't using photos?   :-\

woowww :o amazing man! Really like the way the vegetation worked out. Fantastic!
Rendertime is ridiculous :( My first thought was: I want to see it at least twice the size ;D
Rendering dryad trees is slower than x-frog for example, isn't it?
I'm also wondering if you really would need to have reflectivity on the leaves. Think the specularity trick will do fine enough.

p.s. I'd like to see that stacked surface you've mentioned :)

80 hours? Damn, I'd never have the patience for that..! But I guess the quality of the result pays off, or what? ;) Great job.

Thanks Calico.  Honestly, no image maps.  That new fractal stack works wonders, but you'll laugh at the size of it.

Hi Martin,

I would think the Xfrog trees would render at the same rate since TG2 treats the 3D objects the same.  As for reflectivity on the trees, its very subtle, but adds that extra "pop" needed to keep the trees looking realistic.  Too bad on the render times though.  However, I'd rather a properly done image or no image at all.

Anyway, many thanks for the compliments.   8)

@overlord:  Thanks for the compliments.

@zonic:  Luckily I have 2 dual core PCs sitting off to the side, ready for my next render.  Once multicore is supported, they are sold and I am getting a quad core PC, for rendering only, and as cheaply as possible of course.  Just like my 2 dual cores, they will just have Windows XP, TG2, and a few GB of RAM.  Barebones.

Um...while you're at it...could you get me one too. Please. For a poor college student.  :'(

Well...if you put it that way.   ;D

Beautiful work!  The colors are completely believable and fantastic!  I'm going to have to take a good long look at Dryad now, as well as experimenting with reflections and luminosity on the leaves.

yea dryad all the way...once I figure out how to texture those things...
