The idea to create this demo/program came from my previous work on a 2D fractal generator. Also I needed a small side project where I could apply the knowledge that I had earned while studying linear algebra and OpenGL"s stencil buffer.

This program is a 3D fractal tree generator-renderer. It features an interactive mode which allows a user to quickly set up and generate a tree by changing a number of parameters. Not enough, the user can also choose whether the tree should look like a fractal or more like a random ( realistic ) tree. Once generated, the tree can be viewed from almost any angle and any distance. In addition, this demo/program also features rendering. Once the user is done setting up the tree, he/she can render it. There are a few parameters for rendering as well. The user can choose whether or not the tree should have a shadow, a reflection and leaves. Finally, the user can also save the rendered image of the tree.
