Converting Triangulations To Grids: (AProposal)

To form such a quadrangulation, we may first seek a coarse triangulation with the same connectivity as the surface. We then convert this coarse triangulation to a quadrangulation. 1

The resulting surface can be either used directly (if the original mesh is well ap-proximatedbya piecewise-smooth surface), or used as the base for a displaced surface. 2 Related work The literature on parameterization, quadrangulation and conversion to high-order surfaces is quite extensive, and we ...

Anisotropic Harmonic Quadrangulation Poster Presentation at Symposium on Geometry Processing 2009 Real-Time Creased Approximate Subdivision Surfaces


The multiprism methodological approach of “quadrangulation” serves to “box” in past safety, efficacy, regulatory, and legal problems.

Our goal is to generate a quadrangulation where all quadrilaterals are strictly convex and has all angles larger than some constant—that is, the minimum angle is bounded.
