Given a real $p$, a point $V$ and a vector $v$, constructs a parabola with focal semi-distance equal to $p$, vertex at point $V$ and direction given by $v$.

Given a real $p$ and a point $V$, constructs a parabola with focal semidistance equal to $p$, vertex at point $V$ and direction given by $[0,1]$.

Given a real $p$ and a vector $v$, constructs a parabola with focal semidistance equal to $p$, vertex at the origin and direction given by $v$.
