Comment(by wcauchois):
The patch I just attached represents my initial work on this issue. I
added Oscar's code to plot3d() to implement the transformation keyword
parameter, and I added the two new plotting functions spherical_plot3d and
cylindrical_plot3d.
I made some minor changes to the original code. I moved the formulae for
the transformations for spherical and cylindrical coordinates out of the
body of plot3d, and into the bodies of spherical_plot3d and
cylindrical_plot3d, since I thought that was a better place for them. I
also added some error handling; the urange and vrange given to plot3d may
be 2-tuples, in which case the variables are implicit -- but we expect
urange[0] and vrange[0] to be the plot variables.
We need to add some documentation for the new features. I think I can draw
upon the examples Oscar provided in his published worksheets to create
doctests for the new functions. Oscar, could you help me come up with
descriptions of cylindrical_plot3d and spherical_plot3d for use in their
docstrings? And more examples are always helpful.
