Crater Lake

Crater Lake, rendered using Blender. Elevation data from SRTM. Prepared raster in QGIS.

 

Protip / memo-to-self: Blender will happily use geoTIFFs as heightmaps if you use "non-color data". This is far better than using PNGs (which at the moment seem to be limited to 256 values, so you get banding).

 

Using micro-displacements (adaptive rendering/subdivision surface) in Blender 2.79. DEM was 6000x6000; before adaptive rendering I could only get 2000x2000 with 8Gb RAM, if I was lucky (and patient).

 

Lit from a low angle, using Blackbody of 3500K to give a 'sunset' feel to the lighting.

 

The lake surface was added manually so the level might be a bit off ;-)
