HARDWARE USED: 486 66Mhz 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.
