The latest PostGIS and QGIS 3D enhancements presented at FOSS4G by Oslandia are available online.We suggest you to have a look on our PostGIS 3D / QGIS 3D video demonstration using SFCGAL library and the QGIS Horao plugin.
A step by step workshop, (really close to the video workflow) is also available online https://github.com/Oslandia/Workshops/tree/master/FOSS4G_2013_PostGIS_3D
We can provide you the full virtual machine on demand, with proper software environment (6GB Virtual Box Image).
We would be really interested in having your advice on these new 3D features, and the use cases you could be interested in. Do not hesitate to get in touch.
