Each BB segment is a tapered cylinder. See Figure 8. We have several implementations of our algorithm. The program creates a tree, each segment of a different color. It also creates the corresponding .pov file for rendering the tree in POV-ray.
Program creates a black tree.
Tree can be rotated about x and y axis by clicking in different areas of the window. This program creates .pov file as well. We have our program implemented as a Java applet. Our tool can be viewed through any Java-capable web browser such as Netscape Navigator 2.0 or Microsoft Internet Explorer 3.0. The applet should have appeared here if you had a Java 1.0-capable browser.
