Generate hillshading from DEM files using Blender.
It's a scripted and slightly enhanced version of Daniel Huffman's famous Blender Relief Tutorial
Try to use the main branch; develop is considered unstable and can be broken.
Requires:
- Blender (not installable via pip)
- rasterio, built with v1.3.9.
-
This method as it is right now has issues at the seams, so for the moment it can only be applied to a single DEM file which should be bigger than your desired are of coverage.
-
The script is not 100% parametrized. Sun size and power are fixed based on my tests
-
I will try to add a scattering sky, so we get a bluish tint to the shadows, and set the Sun's color to something yellowish.
-
This hillshading method is really sensible to missing or bad data, because they look like dark, deep holes.
A couple of images of the shadows applied to my style as teaser, both using only 20 samples and x10 height scale:
Dhaulagiri:
Mont Blanc/Monte Bianco:
Man, I love the fact that the tail of the Giacchiaio del Miage is in shadows, but the rest is not; or how Monte Bianco/Mont Blanc's shadow reaches across the Val Vény to the base of la Tête d'Arp. But also notice the bad data close to la Mer de Glace.
