How to get the DEM obj file

[peterjjin]

Hi your work is very interesting and we were trying to test it on the data we collected. May I know the detailed steps to get the obj file of the DEM? As mentioned in the markdown: the digital elevation models in the DEMsubfolders, are provided by the Upper Austrian government, and are converted to meshes and hillshaded images with GDAL

Similarly, the US government provides the DEM in GeoTiff format, but how to convert it into obj?

Really appreaciate your work.

I had similar doubt, how can we create DEM files for our own trails?

Autocad civil supposedly can do it but so can Qgis which is open source.
