Hi Roberto,
I think we have to separate these topics:
- support for georef PLY binary tins, that begins to be the standard
output from SfM Structure from Motion drone aerial video and photo low
cost surveys.
- SfM output into QGIS
Structure from Motion - A Visual Approach

and I also would insert the support for georef PLY binary tins, that begins to

Hi Larry,
we do not have immediate needs, it's a mid-term goal to make LAS data
available

Hi,
Since LIDAR data 1. has a special data structure 2. is huge and 3.
needs index, using a database with QGIS as client seems to me a
natural architectural decision.
As you may know, PostgreSQL has a pointcloud extension made by the
"father" of PostGIS, Paul.

Can it performs fast enough to display hundred millions points or

I suppose you mean:

There was some discussion about LAS format and PDAL on the GDAL mailing
list a few weeks ago, there is probably some interesting info there.

Hi Paolo,
This would probably be quite a different way of dealing with the data
source. I suppose the idea would be to fetch all the points at once and
store them in a kd-tree. Otherwise, refreshing the canvas would take
ages to refresh.

Hi,
if I'm not wrong last year we have proposal for GSoC project with goal
to add native support for LAS data to QGIS [0]. Unfortunately this project
was not accepted.
Maybe we can found contacts of the author of this proposal and look
if he available for help?

Hi all.
Lidar data in LAS format are increasingly widespread. Leaving aside all 3D
frenzy, we
would be interested in simply displaying them in QGIS, with their useful
