A topical visualisation today after I wondered whether I could do this whole flood map thing in 3D.   What I’d really like to do next is have the rule file change the building colour as the water level rises… It can be done just not very nicely.  It also demonstrates the real potential of CityEngine to become a responsive Geodesign tool.

This would obviously be a ridiculously large flood, it’s proof of concept really

Yes you can do this all in other packages but in CityEngine I can change the flood height variable and the model changes pretty much instantly (video to come).   I’ve obviously done some pre processing work in ArcGIS to allow for it to work in CityEngine.

  1. Good work. It’s nice to see a real-world application of the CItyEngine procedural modeling capabilities, especially in how your model is dynamic with a change to an input.

  2. There is a real need for flood modeling at a neighborhood or city scale and in 3D. People just don’t relate to a polygon in 2D. When they see it in 3D, the visceral impact of a potential flood, rising up the sides of buildings, could get people to act and improve their storm water systems or restore their ecological infrastructure like Kongian talked about at the 2014 Geodesign summit. Lots of folks thinking about how to visualize flooding in 3D. Can’t wait to see what you’ve got going.
