3 Point Parabola

[asromero (Alfredo S. Romero)]

In Rhino there is a command to build a parabola from 3 points, how can i do that in grasshopper? Or at least a parabola controlling the distance between the 2 upper points and the distance of the vertex at the bottom

If it didn’t exist in a plugin just some line in a code

It’s my first time with c# scripting so i don’t know how to correctly insert the code. I putted the type hint of the inputs as “Point 3D” but don’t know how to continue
