The animated, more complex and more interesting models -- including models created by and for NSF, NIST, & Navy groups are mosly VRML ( ".wrl" ) files as you can see on these pages ( below )
-- the ".obj" Morphing Hand Web demo is below, but it has no textures and the morphing is via interpolations between three ".obj" files ... it works perfectly, but the capabilites there are more limited.
Nasa's WITS ( Web Interface for Telescience ) SAP uses ------------ uses VRML, Java3d, and Java's networking capabilities to control the Mars Rovers ( now entrounte ) and plan their missions, and include students in the fun ( and you download the program binaries & models now ).
NSF Money + VRML + XML + Java3d --> Virtual Chemistry Lab ---------------------------------------------------------- http://www.frontiernet.net/~imaging/virtual_chemistry_lab.html
It uses this VRML ( .wrl ) file texture mapped with his image:

VRML is clear text ( though it can be gzip compressed, so unzip the file if it's not clear text ) and supports basic shapes ( Box, Cylinder, Sphere, Cone ), meshes, animation, sound .. and Human Animation ...
and with Java3d you can animate VRML in your browser.
VRML mailing list on web3d.org ------------------------------- http://www.web3d.org/www-vrml/
post to the newsgroups comp.lang.vrml, comp.lang.java.3d
You can use Java to create VRML, You can use Java to render VRML animations.

Hey flavin, thanks for the info. I tried VRML loader ... Can you tell me if we can set appearance for part of an obj file using VRML loader?
it's been not possible with java3d obj loader. your help is appreciated Henu
---------- Original Message ---------- Subject: [JAVA3D] setting appearance ... using VRML with the Sun VRML Loaders
If OBJ Loaders aren't up to the task then
use VRML with the Sun VRML Loaders ...

You use a VRML Loader for VRML (.wrl files ) and the OBJ Loader for ".obj" files and you can manipulate the Java3d Scenegraph of either once it is loaded into Java3d, but VRML supports more features within the data file and VRML is what I have more experience with.

The Java3d Scenegraph is the key to the power of Java3d.
Sun's Java3d Scenegraph Editor lets you load VRML, see and manipuate the Scenegraph and you can see a Nasa Mars Rover VRML model loaded on my "Nasa" page above, and there's a link to the page where you get the program -- source code and all -- for free.
