Weights and Super-Ellipses

 From:  Fredrik (FREDRIKW)

I made super-ellipse points in Grasshopper, and started to wonder if there is a simple way to represent that shape with NURBS curves.
When i tried with adjusting the weight on the mid point of a 3 point degree 2 curve, it did almost fit the shape of the super-ellipse points but not perfectly.

So anyways, I thought that super-ellipse shape could be a primitive in MOI?
Maybe a good idea, maybe not?
The animation on the wiki page shows how the shape can vary, and of course it could also be made into 3d "super-box"
