Paris Tube Map
As you think of Paris Tube Map, exactly what are you thinking of? In essence a map is a representation of a topology or function. Intended for example a formula such as X=2Y maps a worth of Y to each value of A. Of course you know that mathematicians are weird and sometimes hard to understand but they have you ever seen a schematic map of a subway (underground railway) system? Perhaps you have ever seen the same network of rails descriptive on a more "normal" Paris Tube Map of the town in which it is located? Different Paris Tube Map of the extremely same thing can look quite different.
As you make a Paris Tube Map of any flat area - a "plan" or "elevation" - things are quite simple, but when you make an effort to map a larger area, like the surface of an whole planet, things can get quite complicated if you wish your map to be smooth. It really is all very well to make an earth, but try turning the of that globe into a set Paris Tube Map! Yikes!
However you begin it, you ending plan edge-effects. As I write this information I am actually included in programming map-generating programs designed to generate maps of fictional landscapes. I happen to be examining the map-generators that are included in the free, open-source (GNU GPL licensed) strategy game, FreeCiv. Edge results are incredibly apparent in such maps. The Paris Tube Map are basically rectangular, but you can choose to acquire them act like cylinders by "wrapping" left to right or top to bottom level, or you may also have "wrap" in both guidelines. Most often people make a decision on "wrap" only remaining to right, and stop the best and bottom with "polar regions". Such simplified "wrapping" makes for quite extreme distortion though if you give it a try with a real Paris Tube Map on the planet!
