Core Calculations

The shared photometry model describes how light is distributed by direction. Workbench can produce directional detector data; IntensityView can import, inspect and modify distributions and use them in lighting assessments. A common intensity distribution does not imply that every application exposes the same reports or calculation settings.

• Quantities and units: flux, intensity, illuminance and luminance.
• Angular data and symmetry: coordinate systems, sampling and the complete angular domain.
• Integration and assessment: solid-angle weighting, normalization and interpretation.

These pages describe the physical foundations. For the settings, assumptions and output of a particular report, use its application documentation.
