Physical Map Definition
At the time you think of Physical Map Definition, exactly what 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 Times. Of course everybody knows that mathematicians are weird and sometimes hard to understand but they have you ever seen a schematic map of a subway (underground railway) system? Maybe you have ever seen the same network of rails descriptive on a more "normal" Physical Map Definition of the location in which it is located? Different Physical Map Definition of the extremely same thing can look quite different.
At the time you make a Physical Map Definition of any flat area - a "plan" or "elevation" - things are quite simple, but when you make an effort to map a larger area, including the surface of an complete planet, things can get quite complicated if you wish your map to be smooth. It really is all very well to make a world, but try turning the area of that globe into a set Physical Map Definition! Yikes!
However you begin it, you conclusion program edge-effects. As I write this content I am actually engaged in programming map-generating programs meant 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 extremely apparent in such maps. The Physical Map Definition 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 even have "wrap" in both guidelines. Most often people make a decision on "wrap" only remaining to right, and obstruct the best and bottom with "polar regions". Such simplified "wrapping" makes for quite extreme distortion though if you test it with a real Physical Map Definition worldwide!
