[Radiance-general] Average illuminance of polygon in scene

[Giulio Antonutto]

Is this to calculate the average exitance of the scene?

you can read the polygon geometry and average the coordinates, then use the normal to offset a point.
some math required but not impossible.
Alternatively with UV maps and the script I have donated in the London Radiance workshop
