I think that would have to be another drawing mode entirely.
This scheme is an addition to pm3d, where the sampling of the
surface is fairly coarse.  If isosamples are left at the default,
that's only 100 "pixels".

What you're describing is more like a texture map.
Input a NxM pixmap, distort/project it onto a surface defined
by an explicit function or coarse sampling.
