Question

I copied the code into a file to play with to see what I could figure out.
below is my failed attempt at getting it to compile. and below that are my errors.
it doesn't recognize the javax.media.j3d or com.sun.j3d.utils
//import Program Files\Java\j2re1.4.0_01
import javax.media.j3d;
import com.sun.j3d.utils;
import java.awt;
import javax.vecmath;
public class HelloJava3Da extends Applet
  ///////////////////////////////class constructor//////////////////////////////
  public HelloJava3Da()
    setLayout(new BorderLayout());
    GraphicsConfiguration config = simpleUniverse.getPreferredConfiguration();
    add("Center", canvas3D);
    BranchGroup Scene = createSceneGraph();
    scene.compile();
    SimpleUniverse simpleU = new simpleUniverse(canvas3D);
    simpleU.addBranchGraph(scene);
  //////////////////////////////Main////////////////////////////////////////////
  public static void main( String args[] )
    Frame frame = new MainFrame(new HelloJava3Da(), 256, 256); 
  //////////////////////////////Methods/////////////////////////////////////////
  public BranchGroup createSceneGraph()
    BranchGroup objRoot = new BranchGroup();
    objRoot.addchild(new ColorCube(0.4));
    return objRoot;
}following are my errors.
HelloJava3Da.java [2:1] package javax.media does not exist
import javax.media.j3d;

OK, for all of those who find my question interesting..... I don't know what my problem was. I just now searched for 1 minute and found the answers I needed.
Developing and using Java3D (using OpenGL):
you need java3D-sdk ___ http://java.sun.com/products/java-media/3D/1.1.3/download.html
You also need OpenGL ( http://www.opengl.org/ )
Using Java3D:
you need java3D jre (samne website... java3d1_1_3-win-opengl-rt.exe, 1.83 MB)
And of course OpenGL.
