Hello dodos880125,
We would like to give you some general information about the calculation surface and its parameters:
The workplane is implemented according to the standard EN12464-1. You cannot change the parameters of a workplane as they always should be adaptive calculated. So a grid of some points are not defined in this way. It is not possible to change the workplane to a calculation surface.
While a certain grid is used for the different measured values it can always be that some minimum or maximum is between those two points. To pretend this you can choose this parameter “perpendicular illuminance adaptive” for calculating on a surface. Then the value to be determined is not defined on a fixed grid but dynamically in the positions where relevant changes take place.
So, adaptive means a dynamic adaptation of the measuring grid. The number of measuring points is dynamically adjusted in such a way that the minimum and maximum values of the illumination intensity are detected as far as possible. This is useful if there are large differences in the illuminances on the surface. The set number of measuring points therefore only affects the other parameters.
The perpendicular calculation parameter is always perpendicular to the surface, regardless of how the surface is positioned. If the surface is vertical, then both parameters are identical horizontally and perpendicular. As soon as the surface is inclined, however, this is no longer the case.
