== Formula ==
With parametrized curves <math>\vec{c}_1(u)</math>, <math>\vec{c}_3(u)</math> describing one pair of opposite sides of a ___domain, and
<math>\vec{c}_2(u)</math>, <math>\vec{c}_4(u)</math> describing the other pair. the position of point (u,v) in the ___domain is
<math>
\vec{S}(u,v)=(1-v)\vec{c}_1(u)+v\vec{c}_3(u)+(1-u)\vec{c}_2(v)+u\vec{c}_4(v)-
\left[
(1-u)(1-v)\vec{P}_{1,4}+uv\vec{P}_{2,3}+u(1-v)\vec{P}_{1,2}+(1-u)v\vec{P}_{3,4}
\right]
</math>
where, e.g., <math>\vec{P}_{1,4}</math> is the point where curves <math>\vec{c}_1</math> and <math>\vec{c}_4</math> meet.
