SunShadow

Description

SunShadow helps to calculate the amount of sun or shade for a three-dimensional surface or a two-dimensional gridded surface. A sun shadow specifies the brightness or darkness for each cell on a raster grid. This depends on how a cell is positioned with respect to a light source, for example, the sun.
