And, if the user chooses a narrow enough boundary emphasis function,
the resulting opacity function does just have one peak, and, the
resulting rendering successfully shows the surface of the dendrite.
So this dataset wasn't ideal- the boundaries weren't totally uniform,
the materials weren't totolly uniform, but it still helped create a
usable opacity function. This dataset comes from limited angle
tomography, which necessarily leaves some artifacts in the boundaries,
and also the tissue dye used prior to scanning is not absorbed
perfectly evenly. That the technique worked on this kind of dataset
is very useful.
