Trying to create m\u00f6bius strip<\/a> mesh using a script..<\/p>\n

Founded some formulas here: (and it even has .obj exporter, but rather do it inside unity..)<\/em>

\u00a0TODO:<\/strong>
\n– Build mesh (m\u00f6bius strip)<\/p>\n

** Well there is now better ready working unity version available here: https:\/\/bitbucket.org\/alexzzzz\/procedural-shapes-for-unity<\/a><\/p>\n

So this one was not finished, here is the current source: (MobiusMaker.cs)<\/p>\n
