Huang He River Map
At the time you think of Huang He River Map, exactly what are you thinking of? In essence a map is a representation of a topology or function. Pertaining to example a formula such as X=2Y maps a worth of Y to each value of A. Of course we all believe 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" Huang He River Map of metropolis in which it is located? Different Huang He River Map of the extremely same thing can look quite different.
At the time you make a Huang He River Map of your 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 need your map to be smooth. It can be all very well to make an earth, but try turning the top of that globe into a set Huang He River Map! Yikes!
However you start it, you finish program 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 extremely apparent in such maps. The Huang He River Map are basically rectangular, but you can choose to obtain them act like cylinders by "wrapping" left to right or top to bottom level, or you can also have "wrap" in both guidelines. Most often people make a decision on "wrap" only still left to right, and prevent the most notable and bottom with "polar regions". Such easy "wrapping" makes for quite extreme distortion though if you try it out with a real Huang He River Map on the planet!
