Guys i highly recommand this :  `https://github.com/Gaia3D/mago-3d-terrainer`

I spent 2 days debugging ctb src code due to tif to quantized mesh. generated range error.
Then just spend 5 minutes get perfect result:

```
docker run --rm -v "./:/workspace" \
gaia3d/mago-3d-terrainer \
-input /workspace/storage/terrain/base_dem2_4326.tif \
-output /workspace/geotiff-terrain-output -maxDepth 14
```
