the Java3D documentation leaves room for desire. I am currently working on submitting 4 requests for possible API to build in my Object Oriented 3D API course, and I have been taking the last two days looking at what Java3D has, versus what other 3D API with scenegraphs have(mainly looking at xith).The API I will probably push hardest for proposal(since it looks like there is the most material on it) is creating smooth, connected surfaces. Although I will probably get more into details of the proposal when I get time to write down my ideas, since I am more working on making the interfaces and summaries of the 4 API at the moment.
