In the java3d-1_2_1-doc files, under PickTool class, it says that... "If the pick shape is a PickBounds, the pick result will contain only the scene graph path, even if the mode is GEOMETRY_INTERSECT_INFO." Does this also apply to using setShapeConeRay, setShapeConeSegment, setShapeCylinderRay,

While debugging a problem with my home-grown 3DS loader, I found something (wrong?) with going from AxisAngle to Matrix to Quats. 3DS format stores rotations in AxisAngle format. I use these to load a Matrix so I can "sum-up" rotations (using matrix multiplies of course). Then, I set a Quat with
