Java3d and VRML share a Scenegraph structure ( they differ in detail ) and a gentle introduction to Java3d scenegraphs can be made by transitioning from web interactive 3d Java 1.1 applets using VRML to Java3d, using the same VRML, as shown here ...
Scenegraphs with Java 1.1, Java3d & VRML ---------------------------------------- - Java 1.1 web applet loades VRML scene and renders SceneGraph, animated Seamless avatar (H-Anim) http://www.frontiernet.net/~imaging/seamless_avatars.html http://www.frontiernet.net/~imaging/java3d_and_vrml.html http://www.frontiernet.net/~imaging/games_with_java3d.html http://www.frontiernet.net/~imaging/java3dviewer.html First and last links above use Java 1.1 and work on Windows, Linux, and the Macintosh ( although unfortunately not with all VMs ). Interactive Scenegraph with Java3d & VRML ----------------------------------------- | The program reads a 3d scene as a simple | VRML text file, and displays the | Java3d Scene Graph ( which is interactive, | you can expand and collapse the branches | of the scenegraph and examine the contents | of the nodes ), it renders the 3d scene, | and when you click on an object it tells you | what you clicked on. | | You can see ( and download ) the Java Source code | of the operative file: VrmlPickingTest.java | http://www.frontiernet.net/~imaging/games_with_java3d.html http://www.frontiernet.net/~imaging/sourcecode/VrmlPickingTest.java http://www.manning.com/selman/selman_source.zip * uses the popular & reliable Sun VRML Loaders. | 3D World Simulation [ Java3d, Source Code available ] | ------------------- [ includes Scenegraph & VRML Loader ] | | I am building up these web pages to hold | everything you need to know about 3D simulations | and models. | | There is theory about 3D modeling, animation and | physics, and there are tutorials and a working a | Java3D editor to allow you to build and experiment | with 3D worlds [ including SceneGraphs, VRML loader ] | http://www.martinb.com/mjbWorld/intro.htm http://www.martinb.com/ Sun's Java3D FlyThrough Demo & the Sun VRML Loaders -----------------( source code free & freely available ) http://java.sun.com/products/java-media/3D/flythrough.html http://java.sun.com/products/java-media/3D/ - Load & View VRML Scene, lights added if desired. | I have to create a 3D scene using java3D, | and be able to navigate in it. | | The scene can be very simple consisting | of a few cubes and a path, a circle can | be used to represent the user and navigation | can be via keys, mouse or both. | | I was wondering does anyone know if there | is sample code anywhere that does something | similar to this. or if there is any sample | code anywhere that could be adapted to | achieve this. | | I have never used Java3D before, | so any suggestions would be very much | appreciated. | [ Grace wrote to Java3d-interest on March 21, 200 ] | http://archives.java.sun.com/cgi-bin/wa?A2=ind0203&L=java3d-interest&P=58511 | Take a look at J3D org's utilities for keyboard navigation: | http://www.j3d.org/utilities/keyboard.html | | This will give you the difficult part | of your program (ie the navigation). | The job of adding a bunch of cubes and | so one isn't very difficult. | Just see the tutorials on the Sun page | (especially chapter 2: creating content) | http://java.sun.com/products/java-media/3D/collateral/ | | If you want to load VRML files for your world, | then you might want to look at Xj3DLoader at: | http://www.web3d.org/TaskGroups/source/xj3d.html | | These should set you on your way! | http://archives.java.sun.com/cgi-bin/wa?A2=ind0203&L=java3d-interest&P=58682 Right, and the Sun VRML Loaders work nicely and have been used for games, Scenegraph Demos, the Sun Java3d Fly Through Demo, and I've used it for my VRML Viewers. Sun VRML Loaders for Java3d: Games, Movies, Demos, Etc. ------------------------------------------------------ http://www.frontiernet.net/~imaging/java3d_and_vrml.html http://www.frontiernet.net/~imaging/games_with_java3d.html The Sun VRML Loaders can aniamte VRML in a browser, or out, on Windows, Linux, Solaris and other Unixes, and can animate Web3d's H-Anim Avatars with Joints animated and TouchSensors triggoring Gesture Animations. Justin Couch has claimed the Sun VRML Loaders can't be used to animate Web3d's H-Anim Avatars but that's a lie, and since he and Aaron Walsh tried & failed to do it he got Prentice Hall to publish that no one can, but you can, and I have. -- Paul, Java Developer & Web Animator. --------------------------------------- "Imaging the Imagined: Modeling with Math & a Keyboard" cc: Prentice Hall : You were deceieved but we know better. =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
