From theCambridge English Corpus The new edges are marked by line segments and the faces by the quadrilaterals formed. From theCambridge English Corpus In its present version, it can use both triangular andquadrilateralcells, albeit only in cylindrical geometry. From theCambridge English Corpus Of course, the shape functions depend on the polynomial order chosen and on the geometric type of the element (namelyquadrilateralor triangular). From theCambridge English Corpus Not all lots are quadrilaterals, as some may have more than four sides. From theCambridge English Corpus The shape is par titioned into triangles, aiming to simplify the shape into aquadrilateral. From theCambridge English Corpus These diagrams result in a series of quadrilaterals, which are constrained to parallelograms if there are no interactions. From theCambridge English Corpus This is clearly not so relevant to the general triangular andquadrilateralmeshes that we are concentrating on. From theCambridge English Corpus Complicated domains must be built up by gluing togetherquadrilateralpatches on which locally sparse grids are employed, or by appropriate mapping techniques. From theCambridge English Corpus She proposed a top-down approach where the recursive division of quadrilaterals into one or more quadrilaterals described the analyzed urban layout. From theCambridge English Corpus First, the sparse grid approach is limited to (topologically)quadrilateraldomains due to its tensor product nature. From theCambridge English Corpus A regular vertex in this setting is a vertex with valency 4, and a regular face is also of valency 4, namely, aquadrilateralface. From theCambridge English Corpus Note that, after one subdivision iteration, all the faces arequadrilateral. From theCambridge English Corpus Observe that if a quadruple of blocks belongs to 10 then these blocks must form a near-completequadrilateral. From theCambridge English Corpus We call such a closed domain enclosed by a pair of increasing curves and a pair of decreasing curves aquadrilateral.
