<br>
</span>PointCloud is actually a PostgreSQL extension, and can work without PostGIS.<br>
There are convenience functions on top of PointCloud and PostGIS to allow data<br>
to be converted to and from both data types and do spatial filtering.<br>
<br>
It is activated like this :<br>
<br>
CREATE EXTENSION postgis;<br>
CREATE EXTENSION pointcloud;<br>
CREATE EXTENSION pointcloud_postgis;<br>
<br>
This is therefore not really a PostGIS extension per se, as SFCGAL would be.<br>
My 2 cents.<br>
<br>
