A potygonat region is a closed region of the plane formed by cutting holes bounded by polygons out of a region bounded by a polygon. Vertices [e@es] of a polygonal region are vertices [edges] of the bounding polygon and the hole polygons. A chord of a polygonal region is a line segment inside the region joining two vertices. Decomposing a polygonal region into quadrilaterals means adding chords, no two of which cross, so that the minimal regions formed by the chords and edges are quadrilaterals…

A linear–time algorithm is presented that decomposes a convex polygon conformally into a minimum number of strictly convex quadrilaterals and proves that the problem of constructing a minimum conformal refinement of a mesh in the three–dimensional space is strongly –hard.

Not all polygons or sets of points admit quadrangulations, even when the quadrangles are not required to be convex, as well as some related computational problems.

### Minimum Weight Convex Quadrangulationof a Constrained Point

• Mathematics

A convex quadrangulation with respect to a point set S is a planar subdivision whose vertices are the points of S, where the boundary of the unbounded outer face is the boundary of the convex hull of

### Minimum Convex Partitions of Polygonal Domains

A new algorithm to convert triangular meshes of polygonal regions, with or without holes, into strictly convex quadrilateral meshes of small bounded size is introduced and an evaluation of the quality of these meshes with respect to a quadRilateral shape quality criterion is presented.
