On Smooth Bicubic Surfaces from Quad Meshes
Determining the least m such that one m×m bi-cubic macropatch per quadrilateral offers enough degrees of freedom to construct a smooth surface by local operations regardless of the vertex valences is of fundamental interest; and it is of interest for computer graphics due to the impending ability of GPUs to adaptively evaluate polynomial patches at animation speeds. We constructively show that ...
متن کاملOn the complexity of smooth spline surfaces from quad meshes
This paper derives strong relations that boundary curves of a smooth complex of patches have to obey when the patches are computed by local averaging. These relations restrict the choice of reparameterizations for geometric continuity. In particular, when one bicubic tensor-product B-spline patch is associated with each facet of a quadrilateral mesh with n-valent vertices and we do not want seg...
متن کاملBicubic G1 interpolation of arbitrary quad meshes using a 4-split
We present a piecewise bi-cubic parametric G1 spline surface interpolating the vertices of a quadrangular surface mesh of arbitrary topological type. While tensor product surfaces need a chess boarder parameterization they are not well suited to model surfaces of arbitrary topology without introducing singularities. Our spline surface consists of tensor product patches, but they can be assemble...
متن کاملEfficient Face-Based Non-Split Connectivity Compression for Quad and Triangle-Quad Meshes
In this paper we present an efficient face-based connectivity coding technique for the special class of quadrilateral and the hybrid triangular-quadrilateral meshes. This work extends the main ideas of non-split encoding presented by the first contribution of the authors (Khattab, Abd El-Latif, Abdel Wahab and Tolba, 2007) for triangle meshes and improves over the compression results provided s...
متن کاملRemarks on Flexible Quad Meshes
A quad mesh is a discrete surface consisting of planar quadrangles. There are some examples where this polyhedral structure consisting of rigid faces, but variable dihedral angles, is continuously flexible, e.g., Miura-ori, Voss surfaces or Kokotsakis’ example which starts from a regular tiling of the plane by congruent convex quadrangles. The classification of all flexible quadrangular meshes ...
