Hi Andreas, If the point cloud data is static and used by several users, I usually triangulate it once into its own seperate file (.ply, which seems to be supported by Qt3DRender::QMesh) for further access.
For a generic cache, maybe 3D Tiles can fit the need for both mesh and point cloud : https://github.com/AnalyticalGraphicsInc/3d-tiles Le vendredi 03 novembre 2017 à 17:28 +0100, Andreas Neumann a écrit : > Hi, > While exploring QGIS3D more, I noticed that my terrain is > triangulated each time I load the project. > I wonder if it wouldn't be better to store this triangulation along > with the Geotiff storing the DEM, e.g. in a sidecar file.
