Smooth spline surfaces over irregular meshes
An algorithm for creating smooth spline surfaces over irregular meshes is presented. The algorithm is a generalization of quadratic B-splines; that is, if a mesh is (locally) regu...

Smooth Bi-3 spline surfaces with fewest knots
Converting a quadrilateral input mesh into a C1 surface with one bi-3 tensorproduct spline patch per facet is a classical challenge. We give explicit local averaging formulas for ...

Hierarchical Spline Approximation of the Signed Distance Function
We present a method to compute the medial axis of a smooth curve or surface by using PHT-spline (polynomial splines over hierarchical T-meshes) hierarchical approximation. In part...

G2 Tensor Product Splines over Extraordinary Vertices
We present a second order smooth filling of an n-valent Catmull-Clark spline ring with n biseptic patches. While an underdetermined biseptic solution to this problem has appeared ...

High-Quality Rendering of Quartic Spline Surfaces on the GPU
Abstract-- We present a novel GPU-based algorithm for highquality rendering of bivariate spline surfaces. An essential difference to the known methods for rendering graph surfaces ...
