Hello,
I guess this question crosses both forums. I am using the vrml-java3d
Working Group's loader and am having trouble with
com.sun.j3d.loaders.vrml97.load(String pathname). It
works fine if I give it a relative path name to the file. However, I am using
the
java.awt.FileDialog to grab files from a subdirectory called "Models".
I use Filedialog.getFile() which returns the file itself, without the "Models/"
in
front of it. I pass this to load() which tries to be helpful and prepends the
path
name of my working directory (up to but not including "Models/"). So, I get:
D:\blah-blah-blah\file.wrl
instead of
D:\blah-blah-blah\Models\file.wrl
I tried setting basepath by calling
com.sun.j3d.loaders.Loader.setBasePath() with the
name of the directory (including "Models/") returned from
FileDialog.getDirectory(), but the load() method appears
to ignore it even though getBasePath() reflects the
desired basepath! If I give it the absolute path to the
file, it insists on prepending the basepath anyway. The
source code supplied with the VRML97 loader
(stamped "VrmlLoader.java 1.13 98/11/05 20:33:08")
appears to apply basepath correctly...
private void LoadFile( String basepath, String geomfile )
{
try
{
// Load a geometry file.
VrmlLoader modelLoader = new VrmlLoader();
System.out.println( "Basepath="
+ modelLoader.getBasePath() ); // prints "Basepath=null"
System.out.println( "Loading \"" + basepath
+ geomfile + " ..." ); // looks correct
modelLoader.setBasePath( basepath );
System.out.println( "Basepath="
+ modelLoader.getBasePath() ); // looks correct
Scene scene = modelLoader.load( geomfile ); // uses wrong basepath
System.out.println( "File loaded." );
if( scene != null )
{
BranchGroup sceneGroup = scene.getSceneGroup();
modelTransformGroup.addChild( sceneGroup );
}
}
catch( FileNotFoundException e )
{
System.out.println( geomfile + ": " + e.getMessage() );
}
I am using VRML97 BETA2 "REV C" on NT 4.0 SP4 w/
jdk1.2 and j3d1.1.
Wa hoppin? Thanks,
-Gary
