Java3D: Probleme mit Box Colorierung und Texturierung

[Guadrion]

Hi Leute,
folgendes Problem:

Ich habe eine Box und möchte deren Seiten verschieden colorieren und möchte nur auf das Dach des Cubes eine Textur legen. Allerdings lässt die Apperance Klasse nur globale Änderungen zu. Habr ihr eine Idee?

Hallo,

hier die Sourcen des com.sun.j3d.utils.geometry.ColorCube:

package com.sun.j3d.utils.geometry;

import javax.media.j3d.QuadArray;
import javax.media.j3d.Shape3D;

public class ColorCube extends Shape3D
{
  private static final float[] verts = { 1.0F, -1.0F, 1.0F, 1.0F, 1.0F, 1.0F, -1.0F, 1.0F, 1.0F, -1.0F, -1.0F, 1.0F, -1.0F, -1.0F, -1.0F, -1.0F, 1.0F, -1.0F, 1.0F, 1.0F, -1.0F, 1.0F, -1.0F, -1.0F, 1.0F, -1.0F, -1.0F, 1.0F, 1.0F, -1.0F, 1.0F, 1.0F, 1.0F, 1.0F, -1.0F, 1.0F, -1.0F, -1.0F, 1.0F, -1.0F, 1.0F, 1.0F, -1.0F, 1.0F, -1.0F, -1.0F, -1.0F, -1.0F, 1.0F, 1.0F, 1.0F, 1.0F, 1.0F, -1.0F, -1.0F, 1.0F, -1.0F, -1.0F, 1.0F, 1.0F, -1.0F, -1.0F, 1.0F, -1.0F, -1.0F, -1.0F, 1.0F, -1.0F, -1.0F, 1.0F, -1.0F, 1.0F };

  double scale;

  public ColorCube()
  {
    QuadArray localQuadArray = new QuadArray(24, 5);

    localQuadArray.setCoordinates(0, verts);
    localQuadArray.setColors(0, colors);

    setGeometry(localQuadArray);

    this.scale = 1.0D;
  }

  public ColorCube(double paramDouble)
  {
    QuadArray localQuadArray = new QuadArray(24, 5);

    float[] arrayOfFloat = new float[verts.length];
    for (int i = 0; i < verts.length; ++i)
      arrayOfFloat[i] = (verts[i] * (float)paramDouble);

    localQuadArray.setCoordinates(0, arrayOfFloat);
    localQuadArray.setColors(0, colors);

    setGeometry(localQuadArray);

    this.scale = paramDouble;
  }

  /**

  public Shape3D getShape()
  {
    return this;
  }

  public double getScale()
  {
    return this.scale;
