Tang Dynasty Map
At the time you think of Tang Dynasty Map, exactly what 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 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 specified on a more "normal" Tang Dynasty Map of the location in which it is located? Different Tang Dynasty Map of the extremely same thing can look quite different.
At the time you make a Tang Dynasty Map of the 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 complete planet, things can get quite complicated if you would like your map to be toned. It truly is all very well to make a world, but try turning the top of that globe into a set Tang Dynasty Map! Yikes!
However you begin it, you finish plan edge-effects. As I write this post I am actually engaged 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 Tang Dynasty Map are basically rectangular, but you can choose to acquire them act like cylinders by "wrapping" left to right or top to lower side, or you may even have "wrap" in both guidelines. Most often people determine on "wrap" only kept to right, and obstruct the very best and bottom with "polar regions". Such easy "wrapping" makes for quite extreme distortion though if you give it a try with a real Tang Dynasty Map worldwide!
