[postgis-users] Visualizing PostGIS 3D geometries

[Rémi Cura]

Hey,
I went trough a similar quest recently.
The only solution I found that worked easily was to export the 3D
shapefile,
and visualize it in an external software
(in my case , CloudCompare )

Sadly it's difficult to find a mature x3d viewer.

Cheers,
Rémi-C
