Cesium plugin to add textured building from a WFS source

Cesium-buildings

This Cesium plugin allows you to visualize textured 3D objects coming from a WFS server.

It is currently mainly used to display buildings.

It currently features :

• Tiling
• Textures
• Object Picking

You can see a demo video here : https://vimeo.com/119770865

Global Architecture

The setup we use to serve 3D buildings to Cesium is the following one :

• PostGIS 2.0+ database with 3D and SFCGAL support
• 3DCityDB importer to read CityGML and import it to the database
• Latest TinyOWS to provide WFS web service for PostGIS data
• Static file served by Apache for textures
• (Optional) MapServer WMS web services for background layer

You can follow our workshop if you want to setup the server infrastructure :

WFS 3D format

Here will soon be the description of the 3D format expected from the WFS server.

Roadmap

• WFS format documentation
• Improve performances
• Object packing
• LOD for geometries
• LOD for textures (with IIP server)

Thank you

Thanks to Grand Lyon for releasing their 3D models as open data.
