Hi Kevin, The order in which the quad and lines are rendered is undefined if the shapes are under a java3d group. To ensure that the lines are rendered after the quad you must place both shapes under an OrderedGroup.
The reason the rendering order is undefined in the general case is to enable Java3D to take advantage of multiple threads and processors.
