IMAGE DESCRIPTION:

This image was inspired by the work of Ralph McQuarrie in the book
"The Illustrated Star Wars Universe". The main object is a Tibanna gas
refinery (pages 144-145) and the balloons floating by are from page 164.
I started by making it a daylight scene with clouds but the background
seemed to take away from the objects so I switched to a night image. I tried
putting in a starfield (lots of tiny spheres) but with radiosity these stars
didn't show up so I took them out. Radiosity adds some amazing lighting effects,
the gas refinery seems to glow inside. I used a big area light off to the left
side of the image to create the smooth shading.

DESCRIPTION OF HOW THIS IMAGE WAS CREATED:

I created several programs to generate scene objects inorder to add some
randomness. The source is included in tibanna.zip.

GENWIN.CPP: This program generates the little windows as boxes. There are 
a total of 15 sets of windows in the scene.

GLGTOWER.CPP: This program randomly positions the light towers that hang below
the big center section of the gas refinery.

DETAIL.CPP: This program randomly generates small detail objects, boxes, cylinders,
cones, spheres, and cylinders with halos on top, that are places on the lower 
portion of the gas refinery.

GENSTAYS.CPP: This program generates all the thin cylinder supports for the 
balloon.

To generate all the necessary include files you need to run BUILD.BAT

The other files included in tibanna.zip are:

BALLOON.INC:  The object definitions for the balloon object
BALLOON.POV:  Test scene file for the balloon object
TIBANNA.INC:  The object definitions for the Tibanna Gas Mine
TIBANNA.POV:  Main scene file used to create final image
LGTOWER.POV:  Test scene file for the light tower object
LGTOWER.INC:  The object definitions for the light tower object
GLGTOWER.EXE: Compiled version of GLGTOWER.CPP
GENWIN.EXE:   Compiled version of GENWIN.CPP
GENSTAYS.EXE: Compiled version of GENSTAYS.CPP
DETAIL.EXE:   Compiled version of GENSTAYS.EXE

The final image was rendered with these parameters:
