You need to add normals to your triangle if you
want to light it.

Confused with the appearance
Try adding this piece of code to your
code:
BoundingSphere bounds = new BoundingSphere();
bounds.setRadius(Double.POSITIVE_INFINITY);
Light light = new
AmbientLight(true, new Color3f(Color.WHITE));
light.setInfluencingBounds(bounds);
objRoot.addChild(light);
light = new DirectionalLight(true, new
Color3f(Color.WHITE), new
Vector3f(0.5f, 0.5f, -1));
light.setInfluencingBounds(bounds);
objRoot.addChild(light);
If the object still does not get illuminated,
I do not have any idea anymore
(I do not have any experience with 3DS
files, so I don't know why its
working
there)

[JAVA3D] Confused with the appearance
Hi,
I had create a simple
application in wich I load an sphere from a 3DS file,
in the same
application y create a triangle of the same size with this
code:
Shape3D shape = new Shape3D();
TriangleStripArray
geometry = new
TriangleStripArray(4,
TriangleStripArray.COORDINATES,
new int[] {4});
Point3d[] points = new Point3d[] {new Point3d(0.3,
0.3, 0),
new Point3d(-0.3, 0.3,
0),
new Point3d(-0.3, -0.3,
0),
new Point3d(0.3, -0.3, 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(1.0f, 1.0f,
1.0f),
64);
appearance.setMaterial(material);
shape.setAppearance(appearance);
objRoot.addChild(shape);
The
sphere has reflection, shadows.... bu the triangle is completly red
without
shadows, reflexion...(color set in the coloringAtributtes of
the
appearance) and if delete the lines of the coloring attributes the
traingle
is completly white. Why the appearance of this triangle is not
been
displayed? The bounds are well
definied.
Thanks,
Boby
