AGi32：a wonderfully fun and interactive rendering program

AGi32 version 19

 

Calculations

AGi32 is a computational program that performs numerical point-by-point calculations of incident direct or reflected light on any real surface or imaginary plane. Within this scope, it is used to predict or quantify the distribution of artificial or natural light in any environment.

 

 

Modeling

AGi32 is a simple yet extraordinary model builder capable of constructing almost any architectural environment. Vaults, domes, curves, slopes and extrusions are easily created, allowing you to accurately model the architectural elements you encounter every day. For those with existing 3D models, AGi32 can import 3D geometry via DWG, DXF and through our LAI Data Exchange (LaiDex) as exported from our free SketchUp plugin.

Rendered: radiosity plus raytrace

 

Rendering AGi32 is a wonderfully fun and interactive rendering program. Employed on this level, AGi32 can be used to generate extremely fast and photometrically accurate color images of the behavior of light within the environment. As the rendering engine is fast enough to be used on an iterative basis, designers now have the ability to quickly visualize and share different lighting scenarios before they are specified, purchased and installed.

Calculations

 

AGi32 is the tool of choice when quantifying the amount of light present in any architectural application. Whether the problem be a 500-luminaire professional sports facility, large shopping mall parking area, commercial interior or single emergency luminaire in a hallway, AGi32 can produce the required numerical results quickly and accurately. AGi32 is used daily to present point-by-point illuminance, roadway pavement luminance, ceiling exitance and other specific lighting quantities for all types of lighting applications. If your position on the design team requires you to submit numeric evidence of lighting quantity and quality, AGi32 is able to produce the data you require.

 

Two Calculation Methods

 

AGi32 has two calculation methods to assist with the computation required in the most efficient manner. For strictly numeric results in an exterior parking, floodlighting, or roadway application, AGi32 has an extremely fast directcomponent calculation engine. The Direct Only calculation method will consider the shadowing effect of objects in the scene and produce point-by-point illuminance on any surface or plane in space.

 

For interior or exterior projects where reflected light is important, AGi32’s Full Radiosity calculation method will compute the interaction between light and surface using its state-of-the-art calculation engine. In this mode all surfaces can be assigned a color and reflectance and accurate luminance levels are computed for the entire environment. An interactive light-accurate rendering is produced automatically.

Photometric Data & Instabase

 

AGi32 can utilize luminaire photometric data in IES (*.IES), EULUMDAT (*.LDT) and CIBSE (*.CIB). These files can be located anywhere on your network, or can be dragged from many manufacturer websites directly into AGi32.

 

Many of the lighting industry’s most prominent manufacturers provide photometric libraries to Lighting Analysts unique cloudbased database we call the Instabase. This is a powerful forum for data access with the ability to specify unique search parameters to query across multiple manufacturers of your choice for products matching your specific needs.

 

 

Specific Calculations

 

AGi32 can perform a variety of illumination engineering calculations for your specification requirements. Which quantities you elect to compute will depend on the lighting application and/or your specific interests.

 

 

Calculation Point Options

 

AGi32 provides a number of different options for locating calculation points. The most effective option will depend on the application and the desired calculations. All options have flexibility in meter aiming (horizontal, vertical, variable, camera).

 • Automatic Placement on any surface or workplane

 • 2-point or 3-point grid specification, flat or sloped

 • Polygon

 • Line

 • Scattered

 • Obtrusive light (Horizontal and Vertical planes)

 • Glare Rating (sports specific)

 • Unified Glare Rating (interior)

 • Roadway criteria
