I have a collection of Bezier curves that forms a network of patches, I'd
like to find out the technique(s) used to generate the patches from those
Bezier curves network.
++ represents a Bezier curve
+

+ also represents a Bezier curve
The following network (attempts with ASCII art) shows a 6 patches
network, 3 columns by 2 rows

Having tried out various modelling/animation software, they all seems
happy to allow a user to just move the end points and the software uses some
form of blending/blendingfuction to find the "inner/interior" four vertices
of each Bezier patch base of the 4 boundary curve and if necessary, the
neighbouring patches. It is this blending/interpolation algorithm/technique
I am keen to find out.
