Widely used in Europe, DIALux recently began breaking into the North American market. The current release, DIALux 4.6, can be downloaded at and is available in 26 languages.

Because the software includes so many different manufacturer fixture libraries, the program retains a type of neutrality. Updated and maintained by an independent company, DIAL GmbH, DIALux is frequently modified and refined to the requirements of designers. A group of more than 90 international luminaire manufacturers funded the development of DIALux and pay to have their luminaires included with the software package. AGI32 is most useful for all lighting calculation needs including simple point-by-point surface calculations, large complex spaces with reflected light and daylight contributions, visualizing light in a space, and basic renderings.ĭIALux, created in 1994, is a free of charge, Windows XP–based radiosity lighting calculation software.

Lighting Analysts also produces Photometric Toolbox Professional Edition, a software program that provides creation, modification, repair, and reporting capabilities for photometric and. That said, the software includes a raytracing engine that can be run on rendered views to visualize specular materials such as glass and polished stone. Although Speer points out that while renderings serve a use for client presentations, AGI’s main functionality focus is its calculations.
The primary goal of AGI32 is to be “as photometrically accurate as possible,” says Dave Speer, co-founder of Lighting Analysts.

AGI was the first commercially available point-by-point program for PC platforms to perform interior computations for irregularly shaped rooms and sloped ceiling configurations.

Featuring a revised, more intuitive interface, an updated luminaire symbol library, function keys that align with AutoCAD 2004, and customizable toolkits that are movable on screen, this user-friendly AGI update has made great strides since the first release of the program in 1992. A 3-D radiosity-based point-by-point and imaging program, AGI calculates both electric light and daylight in most environments. The most recent version of the well-known lighting calculation software AGI32, version 2.0, was released by software company Lighting Analysts in February 2008. Following is an overview of the four leading calculation software packages commonly used in lighting design offices across the United States: AGI32, Lumen Designer, DIALux, and Radiance. Additionally, raytracing can be a slow process, especially if the model contains a large quantity of surfaces.Īll lighting software uses one or both of these two options to calculate the illuminance (the amount of luminous flux per unit area) and luminance (the intensity of light emitted from a surface per unit area in a given direction) of surfaces, and provisions to export lighting calculation data. Unlike radiosity, raytracing is view dependent, meaning renderings must be recalculated from each new angle. Raytracing creates beautiful renderings and presentation-quality images by visually representing light on all surfaces, including the sparkle and highlights on specular materials. This method works for all object types including transparent, translucent, and specular surfaces. Calculation rays are sent outward from a particular viewpoint and the program follows each ray as it hits and reflects off different surfaces and divides into more rays. Raytracing, on the other hand, is a point-specific lighting calculation process. A disadvantage to the radiosity method is that it applies to matte and diffuse surfaces only, so contributions from translucent, transparent, and specular (shiny) surfaces are not included in the calculation. Because of the surface dependency of the calculation, the radiosity method can calculate a model once and produce any desired view. Lambertian reflectance refers to surfaces that have reflected light scattered in such a way that the apparent brightness of the surface is the same regardless of the observer’s angle of view. This method works well for all matte model surfaces since radiosity is based on Lambertian reflectance calculations.

The program then solves the system of equations in the model by determining the quantity of light on each patch as a result of the total sum of all the patches. Each patch is calculated individually for the amount of light that enters or leaves that surface. Radiosity is a calculation method that divides each surface into small pieces, called patches.
