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,

I am searching for advice on how to visualize PostGIS 3D geometries: PointZ, \
PolygonZ, TinZ. So far I have tested out:<br> <br>
* ArcScene - supports pointz and polygonz. but many issues with polygonz and \
confirmed by ESRI<br>
* pg3Dviewer - only supports Pointz. Although, was never able to visualize \
it even with their test dataset and tutorial.<br>
* QGIS - only supports 2D geometry - 3rd dimension ignored<br>
* Grass GIS - extremely difficult to use (I am not a GIS expert): connecting \
to database, creating new mapset, vector map etc. I was able to connect to the \
database and see my tables, figured out the mapset and vector map system. But the \
only thing it seems to pull in from the table is the id column and not the \
geometry.<br> <br>
Honestly, the issues I have gone through to visualize simple 3D PostGIS geometries \
doesn't make sense to me. Shouldn't there be a simple environment to connect \
to the PostgreSQL/PostGIS database and visualize the 3D geometries? Or have I really \
missed something here? If there isn't what is the point in having standardized \
geometries on a S-DBMS if you can't visualize them?<br> <br>
<br>
<br>
Is it expected that some advanced end user develop their own software using some \
visualization toolkit like VTK to visualize these geometries?<br> <br>
<br>
<br>
Many thanks for any advice/guidance.<br>
