IMAGE DESCRIPTION: 

What are visual equivalents to sounds? 
Flowers and birds came to my mind. Directly afterwards the rest 
of the scene arised intuitively - like a dream.
So in this slightly surreal scene flowers and a peacock flow out 
of a violin left back on a park path. 


DESCRIPTION OF HOW THIS IMAGE WAS CREATED:

All trees and plants are modeled with Xfrog
(http://www.xfrogdownloads.com/).
Woman and peacock are DAZ models
(http://www.daz3d.com/shop.php?op=itemdetails&item=1234&cat=)
(http://www.daz3d.com/shop.php?op=itemdetails&item=1068).
Violin is an old mesh from the net - don't know from where anymore.

Starting point was a demo scene of Gilles Tran
(http://www.oyonale.com/ressources/english/xfrog3.htm).

The path function was also used to control planting of grass, trees and 
shrubs. The flowers are planted with my own method from the camera 
point of view (http://news.povray.org/povray.binaries.images/thread
/%3C43236855@news.povray.org%3E/?ttop=218917&toff=50). 

The trunk nearest to camera was substituted by an imagemap dependent 
isosurface to prevent a flat frontier of light to shadow. The code is 
based on Gena Obukhov's work
(http://propro.ru/go/Wshop/objects/objects.html).

Rendering history is a bit complicated. First I rendered the scene with 
2048*1152 pixels and saved radiosity data. Then 14 days were left and I 
rendered a 4096*2304 pixels version reusing these radiosity data. 
This rendering was faster than the first and I used the remaining time 
for rerendering the blotchy iower path part with better radiosity 
settings. The zip file includes an image to demonstrate the difference.
Then a last povray render was used for integrating the partial render 
with the help of a smudged mask, some color correction and resizing.

The pov file is renderable, but uses cylinders instead of the meshes. 
They aren't included in the zip because of their size (size of 
complete source is about 143 MB zipped). 
If anybody wants it, feel free to contact me.
