The calculation surfaces in DIALux can now calculate different types of illuminance. As well as calculating the normal, namely the planar illuminance, perpendicular to the receiving plane, it is now possible to explicitly calculate vertical planar, horizontal planar and camera directed planar illuminance and also semi-cylindrical and cylindrical illuminance.
