Re: [JAVA3D] VRML97 loading and texture rendering

We are in the process of creating a 2.0 version of this loader. If you could send me the test file I'll make sure it works for next version of Xj3D. Likely release date for the next version will be April 20th. I will likely have a test release out sooner so I'll post when I do. Olivier BANASZA

[JAVA3D] Missing files in utils sourcecode

I noticed that the following classes do not have code in the utils sourcecode release. NormalGenerator, Stripifier, StripifierStats and Triangulator. Is it possible to get these files? I'm looking at how to implement the IndexedFaceSets in VRML and I'd like to use these classes. Having really

Re: [JAVA3D] VRML Loaders

If Java3D Fly is using the loader interface(ie time-zero, no animations) loading then I should have an update within the next two weeks, maybe sooner as things are going well in cleaning up the code. Is there an expected follow-up release cycle that I might shot for? Would love to get the latest

Re: [JAVA3D] Bug in vrml loader x3d.jar

Haven't fixed it yet but its now been reported. In the middle of making the vrml-impl compliant so I'll take a peak at this when I get to this node. Looking for a mid april release so hopefully it will be fixed in that release. -Alan Boris Zeldin wrote: > I have a somewhat older version of x3d

Re: [JAVA3D] visualization problem - complex model, VRML97 loader

Been working on improving that codebase recently, but I haven't been playing with indexedfaceset stuff(which I assume thats using). Ya might try rendering it in another VRML browser and see if it responds the same. If so its probably a data conversion issue(converting to VRML). If not then its

Re: [JAVA3D] VR with Java3D

We developed a VR training application on a PC using Java3D that was pushing around 70K polygons on a 800 mhz PC with a Geforce2. Didn't spend much time optimizing it either. So my feeling is that ya can definately develop VR applications with Java3D. Alot depends on how dynamic an environment

Re: [JAVA3D] Dont get it/ Loaders

The loader class does not attempt to convert VRML interpolators to J3D interpolators. If you want the interpolators to run you will need to use the player which will give you a complete VRML event model. Basicly the loader is time-zero, meaning you will get all the geometry and looks but no event

I haen't played with this much, but There is a directory in Xj3D distribution(http://www.hypermultimedia.com/Xj3D/getstart.htm) called Vrmlet. It has an example of an Applet. My hopes is that it doesn't have the same problems... try it out, if you get the same error then I'll take a peak a
