- 3D model of a tube
-
- 3D model of a torus
The third program I have just finished on my C# study is a little XNA program, which renders a given 3D-model with a texture. You can define the camera position and you can rotate the world. I also developped four models with can be switched via shortcut, so you can only see one model a time. There are some more shortcuts available:
- F1: Show 1. model
- F2: Show 2. model
- F3: Show 3. model
- F4: Show 4. model
- F5: Delete one horizontal division
- F6: Add one horizontal division
- F7: Delete one vertical division
- F8: Add one horizontal division
- F12: Reset the configuration
- Arrow-Keys: Move the camera position (X/Y)
- NUM+ and NUM-: Move the camera position (Z)
- SHIFT-Keys: Accelerate the movement and divisions by 10
- Left-Mouse-Down: Rotation the view
- Right-Mouse-Key: Change the fill mode
The models I implemented are:
- Rectangle with TriangleList
- Rectangle with TriangleStrip
- Tube
- Torus
Okay, the first two are not really 3D-models, but it was the starting point that I had to start with and they are really cool, aren’t they? 
All models must be dividable, that means, you can dynamically change the number of subdivision in X/Y direction. After the rectangles I started to build a tube and after the tube I finally worked out on a torus. To implement the torus I worked with the formular given on Wikipedia and iterated over two times PI.
I cannot give you too much details here, because other student may work on their programs for that and I don’t want them to simple copy my results. But if you are interested on these implementations just let me know and I will give more detail later on.
If you would like to test the application, feel free to download the BasicModels installer right here.
Have fun!

This year will be the last Java One… at least it will be the last, that Sun will host, and not Oracle! The first keynote of the conference ended in a surprising appearance by Sun Chairman and cofounder Scott McNealy, who introduced surprise guest Larry Ellison, cofounder and CEO of Oracle Corporation. Oracle’s acquisition of Sun Microsystems is expected to be finalized in the next few months. That’s it, it’s all over, isn’t it?
No it is not! As long as we all trust in the words of Larry Ellison, who spoke about the great effort Oracle has made out of Java and that they will not stop the work on the community. Well, we have to wait, how things will go on, but the Java One will not be the same…
Java One 2009 opening session
The show must go on and so did the conference. I visited very cool sessions, mostly about JavaFX and how things are developing. So I joined the BOF of the JavaFX Designer MeetUp and the sessions held by Richard Bair and Jasper Potts. I like your stuff, keep on rolling! I also went to the session about animations, renamed “Animation rocks”, by Chet Haase and Romain Guy. Awesome session, again, after the one you two guys held at the Devoxx 2008!
Overall scoring: This Java One, even if it is not as big as it used to be the years before (that’s what alumni said) – I really enjoyed my time here at San Francisco. Thanks to all!
