I was wondering how do I approach making such shapes in Dynamo?

List of mathematical shapes and how to create them using Designscript

Hi, I’m on a quest to get the corresponding disignscript of the shapes in this list and get as many as possible If this works it could be a treasure trove for all that come across this thread. I got to this idea because i wanted to draw a parabolic line on paper (2D) , then bend the paper in a parabolic shape, making it 3D, and write it down using designscript. Any help on this one? So this idea of the treasure trove was born, and give this post a “like” if you support it. Y…

Given the equation, this is relatively straightforward, the only real variation would be to start with a circular grid instead of a rectangular grid.

//Circular Grid of Points
p1 = Point.ByCoordinates(Math.Cos(0..360),Math.Sin(0..360));
p2 = p1.Translate((p1.AsVector())<1>,(-1..10)<2>);

//Equation
a = 5;
b = 8;
z1 = Math.Pow(p2.X,2)/Math.Pow(a,2)-Math.Pow(p2.Y,2)/Math.Pow(b,2);

//Surface
s1 = NurbsSurface.ByPoints(p2.Translate(Vector.ZAxis(),z1));
