IMAGE DESCRIPTION: My scene depicts a landscape typical of the Georgian
Bay area of Ontario, Canada.  The background is a typical height field.
I created it with Terrain Maker, and used Paint Shop Pro to create a 
partial image map from it for the green colouring.

For the tree, I wrote an algorithm to create a path if incrementally
shrinking cones, each of which strays by a random amount in a random 
direction.  At the end of the path a cluster of leaves is placed.  The 
program then works its way back to each preceeding joint and completes a
new path.  The end result is a set of forked branches, with each branch
forking again, etc.  This creates a substantial tree without a great
deal of code.  

The bushes use the same algorithm as the tree, but with less segments,
and with more branches from each joint to make them bushier.
