DeskripsiMoebius Surface 1 Display Small.png	A moebius strip parametrized by the following equations: ${\displaystyle x=\cos u+v\cos {\frac {nu}{2}}\cos u}$ ${\displaystyle y=\sin u+v\cos {\frac {nu}{2}}\sin u}$ ${\displaystyle z=v\sin {\frac {nu}{2}}}$, where n=1. This plot is for display purposes by itself as a thumbnail.

Mathematica Code

Please be aware that at the time of uploading (15:27, 19 June 2007 (UTC)), this code may take a significant amount of time to execute on a consumer-level computer.

This uses Chris Hill's antialiasing code to average pixels and produce a less jagged image. The original code can be found here.

This code requires the following packages:
