After I increased sample density, the aliasing issue seems decrease. If I increased too much sample density, the image movement become very difficult. Also the surface will become very dark. Anyway to make the surface more brighter. This is the problem I mentioned before and you suggested me to use TransferFunction to control light intensity. Is that right?
