Details:


Using "slice" with "shading interp" causes different slices covered each
other.
"shading flat" works well
Although "interp3" could be used to interpolate the data beforehand, it costs
a lot of memory and the appearance is not as good as using "shading interp".
Two figures are attatched: one is obtained from using "shading interp"
(slice_1.png), the other is from using "interp3" and "shading flat".
