The four major scenes are generated from the source files in each folder.
The final frame is generated by the files in the Credits folder.

Only the .pov files show any major changes - the .ini files change somewhat, while the 
macros and textures don't change at all, but are included nonetheless.

The .mdl files were used in Moray to position the objects for key frames. They are 
included mainly to show the way IK can be used for moving the frog's limbs. The only
major changes between scenes are the number and position of plants.

The .prj file is from Digital Video Producer, and is probably of no use, but is small.

As the source files were frequently modified while the first few seconds were rendering, I 
cannot guarantee that these files will generate a pixel perfect copy of the entry mpeg. 
This is especially true of the Frog Portrait sequence. Also, the code is messy in parts,
and has some ugly maths where IK has been used, or conversion from right to left handed
coordinate system. Some things that should be deleted are commented out. The paths
for the heightfields will be wrong, and POVray generates warnings for all the Moray groups
that turn out to have only one object inside of them, but were used for IK. Also, the
.ini files may be set up for generating subsets of frames, when only Eat.ini should be.
However, you should be able to get an idea of how I did everything. In my opinion, the 
macros are the most interesting part, being most likely to be used in another animation.

The book "Introduction to Computer Graphics" by Foley, van Damme, Feiner, Hughes and 
Phillips, which is a condenced version of "Computer Graphics: Principles and Practice"
by everyone but Phillips, proved very useful for understanding things like Bezier curves and 
alignment transformations. Obviously the POVray and Moray documentation helped a lot too.
