What about cshep2d and eval_cshep2d?

Just a quick idea:
have you considered using interp2d()

at first look yes but interp2d() use the output of spline2d(x,y,z) where
x and y should be vectors which is a "regular grid"  After a
Joukowski transform the regular grid is transformed like this :

or linear_interpn() to get values on a regular grid?

looks like I search for the reverse function !
