I’ve made a small demo app to experiment with local methods to generate streets for the Infinicity project with interim results at left. The approach the program takes is based on:

• a randomized number of nodes per edge
• a randomized (though so far hard-wired at 2) number of internal nodes per grid unit
• creating edges between the internal nodes
• creating edges between each edge node and the closest internal node

In the real app, the randomization of the edge nodes (both in number and placement) will be based on a simple mathematical combination of the coordinates of the edge vertices, causing neighboring grid units to line up with each other without any direct connection. This is implemented, but disabled in the above app, in order to get a better feel for the variations produced by the process.

If you’d like to see the demo in action, you can download it here.

So I’ve been thinking that the next thing I want to add to the infinite city is a coastline, and that I want the coastline to have piers extending out into the ocean. While thinking about how best to approach that, I started thinking about generating an infinite variety of worn planks with which to construct the piers. I’ve coded up an algorithm that does just that, with results to the left. Haven’t had time to add texture support just yet, but the final version will also select from a few different textures based on random choice and the aspect ratio of the plank.

If you’d like to see for yourself, click here to download the demo app. The arrow keys will rotate around the plank, and F3 will cause it to alter itself. Note that there’s currently no bottom to the plank. I’m undecided as to whether or not to add one, as it adds polygons that aren’t likely to be seen, and a savings of 8 triangles per plank times lots of planks could end up being worthwhile.
