A GPU based interactive modeling approach to designing fine level features
In this paper we propose a GPU based interactive geometric modeling approach to designing fine level features on subdivision surfaces. Displacement mapping is a technique for addi...

A multivariate Powell-Sabin interpolant
We consider the problem of constructing a C1 piecewise quadratic interpolant, Q, to positional and gradient data defined at the vertices of a tessellation of n-simplices in IRn . T...

Volume Refinement Fairing Isosurfaces
We propose an interpolating refinement method for two- and threedimensional scalar fields defined on hexahedral grids. Iterative fairing of the underlying contours (isosurfaces) p...
