Using Blender To Create Java3D Models

Step 1: Download The Programs

    You will need Blender (http://blender.org) and Blend2Java (http://sourceforge.net/projects/blend2java/). Ok then once you have them both start off by making a simple model (or just using the standard cube) in Blender.

Step 2: Export Your Model To XML

            Once you have a model you would like to use in Blender open Edit Mode and hit the "a" key to select all points. In the bottom panel select text editor.

Open a new file in the text editor. Open the blend2java.py file that you downloaded. Run.
Ok your object should now be in .XML wherever you saved it (if you have and error message make shure you only have 1 material for the object). Rename the object (it will have a weird name).

Step 3: Import The Object To Java

Shape3D fred = null;
try {
XMLDecoder e = new XMLDecoder(new BufferedInputStream(new FileInputStream("c:/HandShape3D.xml"))); //your file name here
fred = (Shape3D) e.readObject();
e.close();
} catch(Exception e) {
e.printStackTrace();
}

ColoringAttributes at=new ColoringAttributes();
Appearance ap = new Appearance();
Color3f col = new Color3f(1.0f, 0.0f, 1.0f);
ColoringAttributes ca = new ColoringAttributes(col, ColoringAttributes.NICEST);
ap.setColoringAttributes(ca);
fred.setAppearance(ap);
obj.addChild(fred);

insert this into any 3d code or use the whole code here

use this for a complete program

tada! you are done!
and then you say "now what"?
I have no idea! I just learned Java a month ago lol!
