G'day...

This is the amazing Python script for exporting blender models to XML that can be loaded by the standard java.beans.XMLDecoder class (since 1.4) and cast to the standard Java3D Shape3D object. All clear now?

This allows you to take your amazing Blender models, and bring them across into your Java3D game / app / whatever.

You'll need:
    Blender 2.25 or newer (could work with older ones, never used to) from www.blender.org
   Java from java.sun.com (1.4 is when the java.beans.XMLDecoder arrived)
   Java3D from java.sun.com/products/java-media/3D/
    A reasonable understanding of Blender and Java3d

To use it, you must first select an object you would like to export (in blender)
then load the script export.py, then run it. A file is created for each different Material the mesh has. This is because a Shape3D object can only have a single Appearance node. (But you already knew that)

To load the XML into Java, the following does nicely;

    XMLDecoder e = new XMLDecoder(
        new BufferedInputStream(
            new FileInputStream(filename)));
    Shape3D fred = (Shape3D) e.readObject();

You can see this in action in the demo. To run the demo, go to the demo folder and run

java Viewer

Under windows I think you can just double click on the Viewer.class file, and it will start up, not sure.
There's also a Java3D demo using keyframes, it's bundled in a jar file.

java -jar moo.jar

ithink you can probably double click on that one in windows too.

If you get a class not found "java.beans.XMLDecoder" it probably means you don't have a new enough java runtime, you'll need atleast 1.4.

If you get a class not found "GraphicsConfiguration" or the like, there's a problem with your Java3D installation (did you do one?).

ChangeLog

   - Added a recent changes section to the documentation.
   - The code hasn't changed at all.
