Skymodels gallery

All skymodel hillshades on this page were created by the skymodelling algorithm of the raster chunk processing software, using 2x vertical exaggeration, with a sun at elevation 45°, azimuth 335°. The centre of the image is at 54° 46′ north, 127° 17′ West.

At the top are the five basic lighting scenarios: the uniform sky, the clear sky, the overcast sky, the sharp sky and the turbid sky. Below those come the further 15 more complex skymodels that SkyLum can also produce.
