New description:
line3d for instance calls Line in
/usr/local/sage/3.0.6/devel/sage/sage/plot/plot3d/shapes2.py
Which automatically applies some smoothing using corner_cutoff, which is
buggy and poorly documented as in #3859
(See above Ticket for an example of how this can be bad.)
It is important that I plot lines directly, and automatic smoothing should
either not be automatic, or should be documented,
even for functions that do not reference the smoothing directly like in
Line3d. Perhaps a 'smooth' keyword is more informative than the
undocumented corner_cutoff.
The smoothing is done in the Line class object, and not in pmol, so it can
(and should!) be selectively applied.
Fixing the referenced ticket is a workaround (set corner_cutoff = 1), but
is very clunky, and currently does not even work.
