San Francisco OSM data plus CyberCity3D real world data plus CGA model, plus Lidar, plus a building split by floors, plus satellite imagery!<\/figcaption><\/figure>\n

Without getting into too much detail now (I’m running out of time today) but you can get Lidar data into CityEngine with a bit of work, read on….<\/p>\n

<\/p>\n

The workflow<\/strong><\/p>\n

Basically you convert your LAS data to a multipoint file then convert from multipart to singlepart (in ArcGIS) and import the point data into CityEngine. \u00a0 (was that the worlds shortest workflow?!)<\/p>\n

In CityEngine the model performs fine, lots of small polygons don’t seem to bother it<\/figcaption><\/figure>\n

Now CityEngine does support points, it imports this but converts it into little polygon squares. \u00a0These squares can then have rules run on them, normally I would insert trees on 2D point data, but that would look odd if I did it on a point cloud. \u00a0\u00a0<\/span><\/p>\n

This webscene took a long time to export…..<\/figcaption><\/figure>\n

A word of warning point:<\/strong>\u00a0clouds turn into massive numbers of polygons, you need to bare this in mind when working. \u00a0 CityEngine handles it okay but the export can be very slow…<\/p>\n

That’s a lot of points….argh<\/figcaption><\/figure>\n
