A Hermite interpolatory subdivision scheme for $C^2$-quintics on the Powell-Sabin 12-split [PDF]

, 2014
In order to construct a $C^1$-quadratic spline over an arbitrary triangulation, one can split each triangle into 12 subtriangles, resulting in a finer triangulation known as the Powell-Sabin 12-split.
