#5514: implement exclusions for parametric 3d plots
-------------------------+--------------------------------------------------
Reporter: wcauchois | Owner: wcauchois
Type: enhancement | Status: new
Priority: major | Milestone: sage-3.4.2
Component: graphics | Keywords:

This feature would emulate Mathematica's
[http://reference.wolfram.com/mathematica/ref/RegionFunction.html
RegionFunction]. The user should be able to provide a function to
parametric_plot3d which, given a (u,v) coordinate, would return whether to
include that point in the overall plot. In this way, the user can specify
which region to include in the plot drawn.
The syntax would look something like this:
{{{
var('u,v')
parametric_plot3d([u,v,u^2+v^2], (-2, 2), (-2, 2), region_function=lambda
u,v: u^2+v^2>1)
}}}
This would draw a paraboloid with a circle cut out of the middle.
