As regaurds XJ3D in my code I have managed to load a very basic VRML model though I have a question does the VRML97Loader allow for the importing of interperlators e.g position Interperlators, prototypes and script notes? and If so where can I get information on it like documentation and example code?
Xj3D will handle all of VRML (minus the couple of nodes we don't yet have implemented). As a loader, it will run the majority of it, as best as possible within the limitations of a loader. So, for example we can't do visiblity or proximity sensors (they exist but no events are generated) because we have no information about the location of the user's viewpoint. Other things like navigation are disabled as well. This gets particularly troublesome when you use the loader to load multiple VRML files and place them into a single scene of your own construction as each loaded file would be fighting for the mouse and view position information leading to enormous overheads and really killing performance (we could do stuff allowing for shared context information, but that is well about the spirit and intent of what a loader should be doing).
However, I suspect you are actually asking whether you can directly access the interpolator nodes themselves through the loader interface. If you just stick to the stock Sun Loader interface and the use of the getNamedObject() call, the answer is no. Scene.getNamedObject() returns you a Java3D object that corresponds to that name. The way we have implemented the code is that we do not create any Java3D object that corresponds to the VRML object if it does not have a renderable form - so you would never be able to directly access the interpolators themselves as we do all the interpolation at the VRML level, not at Java3D. To provide a way to access this data, you need to use Xj3D-specific extensions to the Loader interface (org.web3d.j3d.loaders.BaseLoader that gives you back the VRMLScene object, that represents the scene at the VRML level. This will give you access to everything in the scene graph - ROUTEs, PROTOS, DEFs IMPORT/EXPORTs, meta data and the nodes themselves. Note that this is an Xj3D-specific item and would not work with any of the other VRML Loader implementations as they implement their scene graphs and runtime models in completely different fashion. -- Justin Couch http://www.vlc.com.au/~justin/ Java Architect & Bit Twiddler http://www.yumetech.com/ Author, Java 3D FAQ Maintainer http://www.j3d.org/ ------------------------------------------------------------------- "Humanism is dead.
