Hi,
Once you start defining your own materials for objects you have to include
light sources before you see anything. Try adding the following method to
your code and just add the returned BranchGroup to the root of your scene
graph. Obviously this is just to get you started and you can add/customize
light sources to meet your needs.
Hope this helps,
Ewan
public BranchGroup createLights()
{
// Create bounds in which lights are viewed
BoundingSphere infiniteBounds = new BoundingSphere(new Point3d(),
Double.POSITIVE_INFINITY);
BranchGroup light = new BranchGroup();
// Create ambient light
AmbientLight ambientLight = new AmbientLight(true, new Color3f(0.2f, 0.2f,
0.2f));
ambientLight.setInfluencingBounds(infiniteBounds);
light.addChild(ambientLight);
// Create a directional light to show up surface shading
DirectionalLight directionalLight = new DirectionalLight(true, new
Color3f(0.8f, 0.8f, 0.8f), new Vector3f(-1, 0, -1));
directionalLight.setInfluencingBounds(infiniteBounds);
light.addChild(directionalLight);
return light;
} // createLights
