[QGIS-Developer] Choose DEM layer as terrain in 3D view using PyQGIS

[Abdelghani Tamort]

Hello Stefanos,

Thanks a lot, it works for me!
How about showing extruded buildings from a vector layer (using an
attribute containing height in meters)? I'm supposed to work with
the QgsVectorLayer3DRenderer class right ?

Best regards,

Abdelghani TAMORT
