I already got my trac account.  And I just sent the next patch to SAGE for ticket #12532.

SAGE experiment

This time I decided to work with ticket #12532 (an easy one) in order to get envolve with SAGE developer process.  http://trac.sagemath.org/sage_trac/ticket/12532

In the next worksheet you can see how I proceded to understand how plot3d works in SAGE and why it doesn't works in the case the ticket mentions.

And in the next report you can see what I have modified in the source code to patch it.
