Coordinate systemsEdit

Reason
Nominating as a set for various coordinate systems. Could narrow this down to the first three (which are the most common in practical use) if need be as I don't think Oblate spheroidal coordinates are particularly common beyond mathematical interest.

  • Oppose. Confusing. I can't make much sense of these diagrams, even though I know what (spherical|cartesian|cylindrical) coordinates are. MER-C 10:54, 19 July 2009 (UTC)
    • From an article caption: The coordinate surfaces of the spherical coordinates (r, θ, φ). The red sphere shows the points with r=2, the blue cone shows the points with θ=45°, and the yellow half-plane shows the points with φ=−60°. The z-axis is vertical and the x-axis is highlighted in green. The three surfaces intersect at the point P with those coordinates (shown as a black sphere); the Cartesian coordinates of P are roughly (0.707, −1.225, 1.414). So in each case the point is given by the intersection of the surfaces. Noodle snacks (talk) 05:57, 20 July 2009 (UTC)
Yes, I know that. What I meant was the design is confusing, something like File:Coord system SE 0.svg is a lot cleaner. MER-C 09:06, 20 July 2009 (UTC)

  • Oppose This could be an easy SVG target, and can be vectorized to much cleaner versions as MER-C mentioned. Maybe request at GL; I'm already busy with several vectorizations. ZooFari 15:19, 20 July 2009 (UTC)
