Visual's primary function is to calculate illuminance levels at distinct locations in the lighting model for the purpose of lighting system performance verification. This chapter provides a brief overview of the calculations and the techniques for interpreting the results. |

Basic knowledge of lighting equipment and metrics is necessary prior to using Visual to be able to understand the ramifications of choices made in the program and the resultant numbers. Most local sections of the Illuminating Engineering Society provide Fundamentals of Lighting classes to suit this purpose.
An advanced discussion of the Visual Calculation Engine is provided in the Appendices of this manual.
