Huge improvements in the OOB code. It's now able to track the street facing edges of lots.

Fixed the generation of overlapping roofs.

CGAL's docs are pretty good but there's a fair amount they assume you're know. I bought a copy of CGAL Arrangements and Their Applications and found it to be very helpful for filling in those gaps and understanding the architecture.

With a better understanding of arrangements, I started trying to implement the OBB-based Subdivision algorithm described in Procedural Generation of Parcels in Urban Modeling. It's looking promising but I still need to implement the checks that a lot's area is within a range and that it has a certain amount of street access.

In the process I figured out how to get my straight skeleton block division working for shapes with holes:

Farms and Orchards

Got the rows of crops, trees and buildings all using a new instanced drawing system. Looking forward to building out some industrial areas next.

  • Separated the models and views so now buildings that share a BuildingPlan are drawn as instances.
  • Added a concept of a District which has a ZoningPlan that determines how it is divided into Blocks and Lots and which BuildingPlans are used.

Mixing empty lots and parks in with the buildings give it a much more realistic feel.

Started working on an editing mode. Hit spacebar to toggle between it and the view mode.

Sawtooth roofs

Got a basic sawtoothed roof working—more to do to support arbitrary building shapes though


Starting on better block division

  • Started trying to use CGAL's 2D Arrangements for things like creating sawtooth roofs and sub-dividing lots
  • Added a Block mode for testing the subdivision of a single block
  • Upgraded Cinder to 0.9.0

  • Added a building mode to make it easier to get an up-close view of a single building.
  • Added gabled roofs.
