I think there is not enough degrees of freedom in single patch
to do meaningful interpolation. But you might connect the reference
points in such a way that they are at corners of patches (these should
touch) and calculate inner control points for smooth transitions.

See e.g. http://www.joshuarenglish.com/cyclopedia/patches.html
