Can anyone point me to J3D's definition of normals? Or a definition of normals in general?
I don't understand why the normal's direction for a vertex depends on the order in which the vertices are defined. For instance, a TriangleStripArray defined with coordinates and normals: 1.0, 0.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 1.0 faces out from the origin, while 0.0, 0.0, 1.0, 0.0, 1.0, 0.0, 1.0, 0.0, 0.0 faces inwards. It seems that when the vertices are ordered so that the first three are defined clockwise when viewed from the origin, a positive normal points away from the origin. But when the same vertices are defined counterclockwise, a positive normal faces inward.
