Fig. 2

(a) The solid lines form a DS-net here with a central, isolated n = 5-sided facet: one layer of quadrilaterals (4n nodes) surround the n-sided facet. The green patches in the regular extension are bi-2 spline patches. (b) A DS-mesh consist of DS-nets (here n = 3, 5) and regular, tensor-product sub-nets defining a bi-2 spline.
