IMAGE DESCRIPTION: 

Actually, this is my second image for this round. I was first planning to submit
only one entry, when,
suddenly, this idea came to me. My other image was almost ready at that time.
But I just could not
stand the temptation of making this image.

The idea behind it is simple: a wasp nest looks like a julia fractal, or is it
the other way round?
On the other hand, I did a lot of raytracing, but never found any practical
application for a fractal
object. So present IRTC topic gave me a good opportunity both to use other
objects then boxes and
spheres, and to look around...


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 

The text was written in POV-Ray text editor. "Trial and error"raytracing was
used instead of graph
paper. Most of the objects were made as *.inc files (sometimes nested), so that
it was easy to
add/remove them to/from the main scene and raytrace only portions of the image.
I used 320x240
window  (without aa) for test renderings.

I tried to raytrace this image using focal blur and thin blue fog to create the
impression of depth.
It took over one day, and was not as good as the one with just aa0.3. Perhaps,
the number blur_samples
should have been larger, but I had little time left. So finaly I decided to
forget about focal blur

All objects are my own (and made for this IRTC round). They are included in the
.ZIP. Please feel free
to use them.

1. "Nest" is a CSG union of two julia fractals and a CSG union of boxes and
cylinders, representing
honeycomb.
2. "House_on_the_background" is made of CSG unions and differences of a number
of superelepsoids,
boxes, cylinders and prisms.
3. "Stones_on_the_foreground" are heightfields from a bitmap created in POV-Ray,
similar to the one
described in POV-Ray documentation.
4. "Wasp_models" are made of CGS unions of multi-element blobs. They are
completely redisigned
for this IRTC round versions of my earlier models (of two different insects).
They are now much more
flexible (legs and wings can be easily moved), and the random function is added
to simplify the text
when multiple models are used.
5. "Car" is made of CSG of multi-element blobs, wheels are CSG of cylinders,
torii (?!) and boxes.
