I recently became aware of this tool. In my very limited tests for mutidirectional-hillshading, this algorithm is performing very well when compared with some other tools.
Is there some paper/study/webpage the describes the underlying idea behind Multidirectional hillshading algorithm used by whitebox-tools? Or some study/tests that compared it some other hillshading algorithms?
1)I searched for listed reference in your manual, but as far as I can tell nothing is mentioned about the hillshading.

The Hillshade function and the unequal weights given to different azimuths suggests that it is an enhancement over this old algorithm. Not sure if I am correct. https://pubs.usgs.gov/of/1992/of92-422/of92-422.pdf
