Yes, put it into the Background() object. Load up your geometry in one or
more PointArray objects, then add it to the tree as a Background object.
Here's a snippit of code. You also might be interested in how I changed the
brightness of the stars with color.
private BranchGroup createContent()
{
BranchGroup objRoot = new BranchGroup();
Background background = new Background();
background.setApplicationBounds(bounds);
background.setGeometry(createBackGraph());
objRoot.addChild(background);
return objRoot;
}
public BranchGroup createBackGraph()
{
// Create the root of the branch graph
BranchGroup objBack = new BranchGroup();
PointArray orion = new PointArray(10, PointArray.COORDINATES |
PointArray.COLOR_3);
orion.setCoordinate( 0, new Point3f(0.978330f, -0.033900f, 0.204426f));
orion.setCoordinate( 1, new Point3f(0.968007f, -0.167860f, 0.186506f));
orion.setCoordinate( 2, new Point3f(0.981477f, -0.142660f, 0.127873f));
orion.setCoordinate( 3, new Point3f(0.983764f, -0.005220f, 0.179391f));
orion.setCoordinate( 4, new Point3f(0.981112f, 0.110597f, 0.158705f));
orion.setCoordinate( 5, new Point3f(0.967377f, 0.172516f, 0.185523f));
orion.setCoordinate( 6, new Point3f(0.961385f, 0.128845f, 0.243183f));
orion.setCoordinate( 7, new Point3f(0.978330f, -0.033900f, 0.204426f));
orion.setCoordinate( 8, new Point3f(0.981293f, -0.020980f, 0.191375f));
orion.setCoordinate( 9, new Point3f(0.983764f, -0.005220f, 0.179391f));
orion.setColor(0, new Color3f(1.0f, 1.0f, 1.0f));
orion.setColor(1, new Color3f(0.9f, 0.9f, 0.9f));
orion.setColor(2, new Color3f(0.8f, 0.8f, 0.8f));
orion.setColor(3, new Color3f(0.7f, 0.7f, 0.7f));
orion.setColor(4, new Color3f(0.6f, 0.6f, 0.6f));
orion.setColor(5, new Color3f(0.5f, 0.5f, 0.5f));
orion.setColor(6, new Color3f(0.4f, 0.4f, 0.4f));
orion.setColor(7, new Color3f(0.3f, 0.3f, 0.3f));
orion.setColor(8, new Color3f(0.2f, 0.2f, 0.2f));
orion.setColor(9, new Color3f(0.1f, 0.1f, 0.1f));
objRoot.addChild(new Shape3D(orion));
objBack.compile();
return objBack;
}
