Typo on p.16: left Bezier patch of the characteristic map has
a number of transposed entries associated with c_{n}.
The patch should equal the of lower right patch with the sign of the 2nd coordinate flipped.
Correction for tetroid, D_2q, middle column should be [-10 4 -12]
Correction for hexoid, upper left figure, the entries should be
(top left: [-3 0 3], top right [3 0 3] and lower right[3 3 0])

For general modeling I recommend C^1-surface splines.
Surfaces...bicubics is older, uses more patches,
uses more complicated formulas, does not prove the convex hull property.
It is however the first of this type of construction.
