In this paper we consider and analyse NURBS based on bivariate quadratic B-splines
on criss-cross triangulations of the parametric domain Ω0 = [0, 1] × [0, 1], presenting their main
properties, showing their performances to exactly construct quadric surfaces and reporting some
applications related to the modeling of objects. Moreover, we propose applications to the numerical
solution of partial differential equations, with mixed boundary conditions on a given physical domain
Ω, by using three different spline methods to set the prescribed Dirichlet boundary conditions.
