hello,
I am working on a graph like
http://www.openprocessing.org/sketch/7098
(the latter graphics ones are advanced 3D)
now I came across a nice 3D graph in a book with a formula x^n + y^n = 1
with n e.g. 3 or 5; x and y complex numbers.
anyway I don't get how this is 3D since there's no Z; but the graphic in the book is clearly 3D.
I could loop over x and y and paint only those points where the result is 1 allright. But what's my Z?
or has it to do with complex numbers?
lost, Chrisir
