LOS/FOV/projections in NPP/Sangband


I'm working on a variant based on NPP and I want to better understand the type of LOS (and projection and FOV) present in NPP. It is clearly different to the LOS in V and the version comments say that it was taken from Sangband. Indeed, the comments say that the project functions, update_view and line-of-sight all come from Sangband. Does anyone know which algorithms Sangband uses and/or how they differ from the ones in Vanilla?
