I'm probably just missing something subtle here, but as far as I understand projective geometry, there's no "perspective" involved in rendering a sphere - it looks round no matter how it's projected, no? As opposed to a box that can be sheared or distorted in a number of entertaining ways. Right? Wrong? I'm scratching my head here ...[[User:Sgeier|Sgeier]] |

Indeed. But there must be sufficient voodoo to make it not look like a flat circle or disk. |

Task description
A “sphere cuboid”?? WTF… –Donal Fellows 10:57, 25 March 2011 (UTC)
- If I were fooled by the english meaning of that phrase, I would think that the task was to draw a regular cube. However, the image on the PureBasic implementation shows me that at least one person believes differently. --Rdm 16:46, 25 March 2011 (UTC)
Sorry - That was a mispaste. It should just read "sphere".

PureBasic image?
To my mere untrained Layman's eye, this does not look like a sphere. If anything, I'd say, it looks like a butt.Sgeier 16:37, 25 April 2011 (UTC)
