- Hydrogen atom wavefunctions have
structures within structures whch cannot be seen thru solid volumes.
They also have a very specific angular dependence, which cannot be understood
from a single two-dimensional cut such as that provided by a contour plot.
- Smoke rendering is a visualization technique that
is widely used in the engineering literature to indicate density
of fields. Where the density is high the density of smoke (dots) is high
and where it is low the smoke is dilute. The smoke may be colored or white.
