Hi Saber,
It is a good point - to use the source.
I think the source was a point cloud data set.
So, ideally, it could be a point cloud to mesh tool (or TIN).
I see that Alex Bruy just committed a point cloud to raster tool (going
through TIN is an option), but not as a final TIN result.
Hi Andreas,
Indeed, there is no native tool at the moment to convert raster directly to
mesh. I filed a ticket with a link to this discussion so we can add it to
QGIS later:
https://github.com/qgis/QGIS/issues/52313
But, in general, I would first try to find the source of the DEM raster
(e.g.
and there seems to be https://github.com/heremaps/tin-terrain
However, I am looking for a solution integrated in QGIS ...

It would be nice, if QGIS would gain a direct algorithm of creating a
mesh from a DEM - as many DTMs are provided as raster. It seems like
SAGA has a raster DTM to TIN algorithm (
Hi all,
I think it is not nessasary to go through Blender, just use theese two
algorithm:
* pixeltopoints
* tinmeshcreation

Hi Andreas,
There should be a tool to convert vector to mesh (under Processing > Mesh >
TIN Mesh Creation). There will also be some new Processing tools for
handling point clouds. But I am not aware of any Raster > Mesh tools.
Kind regards

Hi QGIS devs,
Is there a tool available to create a Mesh (or TIN as a special mesh
variation) from a source raster layer containing terrain values?
I did not find one - but maybe I didn't look everywhere.
If not in QGIS - do you know an external Open Source tool that could do
that, while
