Hi Rick,
Yes, I am using VrmlLoader, sorry about that. And yes load(
"Models/"+filename) works if I
"hardwire it", however the relative path ("Models/") is not available from the
FileDialog, I guess it is possible
extract the relative path from the absolute path returned from
FileDialog.getDirectory() by comparing it to the
working directory path, but VrmlLoader or more likely it's superclass is not
functioning as advertised. I did
note that when "basepath" is set via VrmlLoader.setBasePath(), that path is
APPENDED to the working directory
in looking for textures when parsing theVRML file, this gives a bogus path name
like:
D:\blah-blah\D:\blah-blah\Models\texture.jpg
All would be simpler if the loader would except an absolute pathname, or
FileDialog returned the
relative path.

Subject: Re: [java3d] Loading files via the vrml-java3d VRML97 loader
Gary,
I take it you mean "com.sun.j3d.loaders.vrml97.VrmlLoader.load()" and not
"com.sun.j3d.loaders.vrml97.load()". If this is the case, did you try
load("Models/"+fileName);
?
