# Cityscape

![Flying](./flying_by_donald_crews.jpg)

This project was inspired by [Donald Crews' book Flying](http://www.amazon.com/gp/product/0688092357).

My wife had gotten the book for our son, but having loved [Truck](http://www.amazon.com/Truck-Donald-Crews/dp/0688104819)

as a child, I fell in love with the style and thought it would be fun to spend

a weekend writing a program to generate a city in his style.

As I worked on an algorithm to divide a blocks into lots, I realized that rather

than a topic for a weekend project, it really a topic for a PhD thesis.

Fortunately. [Tom Kelly has already written that thesis](http://twak.blogspot.com/2014/02/unwritten-procedural-modeling-with.html),

and it's fascinating. His survey of procedural modeling techniques gave me a ton

of ideas and he's included an algorithm for using the block's straight skeleton

to partitioning it into lots.

The goal of this project is an app that will accept a series of roads, and

generate a city of buildings in Crews' style, around them. I decided to use the CGAL

library for its straight skeleton and that forced me to learn a lot about C++

templates, which slowed my progress. But as I've started to discover how to use

it, I found the breadth of CGAL's functionality to be amazing. It may not do it

fast, but it'll do it accurately.
