I while back, I wrote about the project going on at Stanford whereas the ancient stone map of the city once hanging in the public forum, was found crumbled, but mostly complete. Well, like a large puzzle, it was slowly put together, using the help of 3d scanners, and there are suggested solutions available. Well, so what? It serves our left side geeky brain, but that is really it. We now just have a vision of the city as some biased, imprecise mapmakers thought it in the year 42 or whatever. There is so much beyond to think about, to understand (such as the 1400 years that the city survived to the renaissance) that it may be helpful to understand the top down thinking at the start, but I'm more interested in bottom up. See, for example (only conceptually) these procedural texture methods are fascinating. Using Free agents, can one generate Rome, pardon the phrasing, in a day? Hey, it's an idea.
