Irradiance orthographic view

Description

Cornell box rendered with an irradiance orthographic view, illuminance(Y) displayed in false colors with a log scale
scene file

This instrument creates an orthographic image of scene irradiance. Results show how much light is incoming over the visible surfaces. Depending on sensor type, the computed value may be scene illuminance (Y), spectral irradiance, etc...
