Problem is that java3d is purely polygon based. Ray tracing shows it's
strengths when used with constructive geometry and 'real' shapes -
parametric surfaces etc.
I'm afraid that java3d is too low level (sic!) api to make ray tracing
reasonable. From very start it was also meant to be real-time rendering
api - thus some design decisions do no scale very well to ray quality.
