Perform luminance and illuminance analysis and generate reports out-of-the-box.

Luminance and illuminance properties of a scene are the two key factors in lighting design; they describe the energy arriving to our eyes and space correspondingly, but in the way we, humans, perceive and interpret lighting. These properties can be computed out-of-the-box, in parallel with the rendering process. Besides the cool false-color rendering, user can select multiple regions of interest where he can analyze the extreme points and distribution of values. In addition, a full report can be easily generated, that can be viewed in any web browser.

With the addition of this feature, photometric analysis and reports, which are usually found in expensive applications, are delivered with the fidelity and accuracy of Thea Render.

Luminance analysis for a penthouse (modeling by Claudio Pilustrelli) Choose Photometric (Luminance or Illuminance) analysis in the Darkroom

Please note that a) Luminance is computed in Thea Render as the exit radiance leaving the surface and arriving at the camera (in photometric units of course) and b) Illuminance is computed as the irradiance received at the surface (in photometric units), accounting for secondary (indirect) lighting without including direct lighting. Illuminance can only be computed using the Adaptive BSD engine (with Irradiance channel checked before starting rendering).
