Comment:
One more point that I thought of when trying to use this feature. Why
should I have to specify the names of variables more than once?
Introspection should be able to get these from my gen_transform function.
It seems like I should be able to do this:
{{{
class Cylindrical(sage.plot.plot3d.plot3d._CoordTrans):
"""
Some docs for the mathematical definitions of the variables
"""
def gen_transform(self, radius=None, azimuth=None, height=None):
return (radius * cos(azimuth),
radius * sin(azimuth),
height)
}}}
and things should just work. all_vars can be inferred from the keyword
arguments to gen_transform. It's pretty easy to come up with a good
default _name (i.e., 'name of class (variables) coordinate system').
