What are the arrangement issues that arise with respect to three-dimensional plots?
What will be an ideal response?
It would have been better to state this more generally as “What are the issues
. . . ,” since selection, as well as arrangement plays a key issue in displaying a
three-dimensional plot.
The key issue for three dimensional plots is how to display information so
that as little information is obscured as possible. If the plot is of a two-
dimensional surface, then the choice of a viewpoint is critical. However, if the
plot is in electronic form, then it is sometimes possible to interactively change
the viewpoint to get a complete view of the surface. For three dimensional
solids, the situation is even more challenging. Typically, portions of the
information must be omitted in order to provide the necessary information.
For example, a slice or cross-section of a three dimensional object is often
shown. In some cases, transparency can be used. Again, the ability to change
the arrangement of the visual elements interactively can be helpful.
