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.
UniformClearOvercastSharpTurbidType 1: CIE standard overcast sky, alternative form, steep luminance gradation toward zenith, azimuthal uniformityType 2: Overcast, steep luminance gradation and slight brightening towards the sunType 3: Overcast, moderately graded with azimuthal uniformityType 4: Overcast, moderately graded and slight brightening towards the sunType 5: Uniform luminanceType 6: Partly cloudy, no gradation towards zenith, slight brightening towards the sunType 7: Partly cloudy, no gradation towards zenith, brighter circumsolor regionType 8: Partly cloudy, no gradation towards zenith, distinct solar coronaType 9: Partly cloudy, with obscured sunType 10: Partly cloudy, with brighter circumsolar regionType 11: White-blue sky with distinct solar coronaType 12: CIE standard clear sky, low illuminance turbidityType 13: CIE standard clear sky, polluted atmosphereType 14: Cloudless turbid sky with broad solar coronaType 15: White-blue turbid sky with broad solar corona
