Hi all,

Im trying to set up an equasion-driven surface - so I can create a superellipse or hyperellipse (attached jpeg)

All the details for the equasion are outlined in wikipedia (http://en.wikipedia.org/wiki/Superellipse) I also have a handy spreadsheet taken from a website I found which has a table of numbers in there that creates the curve parametrically (attached)

Can anyone help? Scale in dimensional format doesnt really matter at this stage, im just trying to get the curve & shape in there and then tweak all the various numbers to something useable.

Thanks in advance,

Chris
