I'm trying to figure out how I can make a paper model of the corncob water tower in Rochester, Minnesota for my N-scale train layout.
The best I can find is this: http://www.korthalsaltes.com/model.php?name_en=hebdomicontadissaedron
Is there an equation for a corncob-like closed quadric surface?
I suppose I could do trial and error, using a vector graphics package to play around elongating the example above and such, but I'm wondering if there is a mathematical way I can do it?
