Here is some sample code for setting the appearance for a Shape3D object (a
red colored XY-Plane):
Shape3D shape = new Shape3D();
TriangleStripArray geometry = new TriangleStripArray(4,
TriangleStripArray.COORDINATES, new int[] {4});
Point3d[] points = new Point3d[] {
new Point3d(1e6, 1e6, 0), new Point3d(-1e6, 1e6, 0),
new Point3d(-1e6, -1e6, 0), new Point3d(1e6, -1e6, 0)
};
geometry.setCoordinates(0, points);
shape.setGeometry(geometry);
Appearance appearance = new Appearance();
ColoringAttributes ca = new ColoringAttributes();
ca.setColor(new Color3f(1, 0, 0));
appearance.setColoringAttributes(ca);
Material material = new Material(new Color3f(0.2f, 0.2f, 0.2f), new
Color3f(0.1f, 0, 0), new Color3f(1, 0.8f, 0.8f), new Color3f(Color.WHITE),
64);
appearance.setMaterial(material);
shape.setAppearance(appearance);
I guess that your lighting is not enabled as well, since the shape should be
shaded when lighting is enabled. Check the setInfluencingBounds for your
lights to include your Shape3D.
