# Roman Surface

The Roman surface is a quartic nonorientable surface. It – along with Boy’s Surface and the Cross-cap – are the three surfaces that can be crafted by pasting a Möbius Strip to the edge of a disc.

The following is one of its parametrizations (Weisstein (2016)):

$% \begin{split} x(u,v) & = \frac{1}{2} a \sin{2u} \sin2 v\\ y(u,v) & = \frac{1}{2} a \sin u \cos{2v}\\ z(u,v) & = \frac{1}{2} a \cos u \sin{2v}\\ \end{split}%$

where $$u \in [ 0, 2\pi )$$ and $$v \in [-\pi/2,pi/2]$$.
