Generalizing tensor-product splines to smooth functions whose control nets outline topological polyhedra, bi-cubic polyhedral splines form a piecewise polynomial, first-order differentiable space that associates one function with each vertex. Admissible polyhedral control nets consist of grid-, star-, n-gon-, polar- and three types of T-junction configurations. Analogous to tensor-product splines, polyhedral splines can both model curved geometry and represent higher-order functions on the geometry. This paper explores the use of polyhedral splines for engineering analysis of curved smooth surfaces by solving elliptic partial differential equations on free-form surfaces without additional meshing.
