Text Statements in 3D Graphics

Dear MathGroup

Mathematica treats text in 3D graphics so that it is projected forward and
is always visible. In other words, text is never hidden behind a surface.
However, this is often undesirable. Suppose one wishes to label certain
points on a 3D object and then rotate it with SpinShow. It is better not to
display the text labels that are behind the surface. Otherwise the eye
naturally attaches the label to the part of the surface that can be seen,
not to speak of text clutter if there are a number of labeled points. It
would be much nicer if there were an option to suppress Text statements if
the application point is hidden. Perhaps this should even be the normal
behavior. Text in 3D which should always show can be added with the Epilog
option.
