Roads

I haven’t decided how I’m going to represent roads, but it’s very likely that I’ll draw them with quadratic Bezier curves, since that’s what Flash has built in.

This demo shows what roads might look like, and also shows a quadratic bezier curve approximating a circular arc. When the arc angle is less than 1/6th of the circle, the bezier curve seems to be a reasonable approximation, but I may still have to subdivide it to make it match an arc.
