William,
The patch as written gives the same error. However if you
change line 37 of the patch from
if vx == vy == 0:
to
if vy == vz == 0:
(since atan2() is taking arguments vy and vz) then
I get a different error on ia64-Linux:
sage -t devel/sage-main/sage/plot/plot3d/plot3d.py
**********************************************************************
File "plot3d.py", line 19:
sage: S.show()
Expected nothing
Got:
6.0
<type 'sage.rings.real_double.RealDoubleElement'>
0.0
0.0
**********************************************************************
1 items had failures:
1 of 9 in __main__.example_0
***Test Failed*** 1 failures.
