We have produced a number of technical and non-technical documents for this project. You can find them here. But perhaps you are looking for our publications in journals and conferences...
  1. You can see our brochure (pdf, 16Mb)
  2. We presented a live demo of both buildingEngine and how to build a procedural city with Houdini and skylineEngine, on July 2nd and 3rd, in the context of the OpenCobalt presentations organized by Milla Digital and Zaragoza City Council. The corresponding material and demos can be found here!
  3. We have more documentation, but it is fully in catalan. Should you need any explanation beyond the code, do not hesitate to contact us.
