Parametric plane $\mathbf{r}(s,t) = \mathbf{p} + s\mathbf{u} + t\mathbf{v}$ in 3-space
This program renders a plane in R3 given in parametric form r(s,t) = p + su + tv, where p is a point on the plane and u, v are direction vectors spanning it. The parametric representation makes explicit the two-dimensional nature of the plane and generalizes naturally to parametric surfaces. The math.js library parses user-defined expressions for the parameters.
