That's super. I've wanted this functionality for a long
Now, to look a gift horse in the mouth, admire his teeth,
and ask if he can race :), what are the chances for a
complete unification of the various functions in VTK?
There are the spline functions, the piecewise linear
functions for volume rendering, and the implicit functions.
I could even see them in filter kernels. It would be really
great to be able to have a vtkFunction superclass for all
of them, and be able to consolidate them all to some extent.
Seems like there's plenty of commonality, especially when
you go to higher dimensions with separable functions.
