3D DEM generation

[Wmthiab]

hello ,

iam using metashape and i was wondering is there a way to navigate or export the DEM in 3D ? or to mask the 3d tiled model with the DEM ?

Thanks

Hi,

Not exactly from DEM, but this script could be a workaround : it colors the mesh with Z values.

Hope it will fit your needs.

Hello Sébastien,

Do you mind, if we publish your script (with minor changes) on our GitHub repository, as it may be useful for certain cases and demanded by other users?

This is very cool script.

I'm not very good at scripting but is there another script to revert the colors at their original? (colored from point cloud).

Hello Costas,

There's Colorize Vertices command in Tools Menu -> Mesh section. Alternatively you can just duplicate the model before using the script.

Dear all
if I want to proceed to the same idea but on Pointcloud and not mesh or 3Dmodel, which argument should I use instead of chunk.model.vertices in that Seboon's SCRIPT ?

is it chunk.pointcloud.points ?

thanks
antoine

Hello Antoine,

chunk.point_cloud.points provides access to the tie point cloud points.
