LightTools 8.1

LightTools 8.1 delivers new modeling and analysis features for general lighting, automotive and biomedical applications, as well as speed improvements for tracing backward rays and generating photorealistic images.
Additional Multi-CPU Capabilities

LightTools’ multi-threading capabilities, which enable illumination simulations to take advantage of all CPUs or cores on a computer, now support backward simulations and photorealistic renderings. This can dramatically improve the speed and efficiency of these processes, which are important for visually evaluating and communicating illumination designs.

Region Analysis

Designers can now perform a region analysis to examine illuminance and intensity results in a specific area of interest in their 3D models. This provides a quick and easy way to analyze rays that contribute to a particular region of interest in the model and is useful for identifying undesirable hot spots in illumination systems.

New Swept and Freeform Objects

Freeform solids and objects that can be swept along a path provide increased flexibility for designing state-of-the-art lighting components. These objects make it easier to create faceted reflector structures and model complex, 3-dimensional lightpipes and lens-like solid objects that can be optimized using the LightTools Optimization Module.

Expanded Volume Scattering Types

Two new volume scattering types, Henyey-Greenstein and Gegenbauer, expand LightTools’ capabilities for modeling light interactions with scattering materials. Because of their usefulness for modeling the scattering properties of tissues, these scattering types are particularly important for biomedical optics.

Expanded Street Lighting and Automotive Test Point Analysis Utilities

The LightTools Street Lighting Utility has been enhanced to provide a plot for visualizing the roadway from the driver\’s perspective. Based on roadway analysis, the utility can also make independent plots for the illuminance or intensity of a single luminaire at a roadway surface. In addition, the utility now supports files in Eulumdat format, the industry standard for photometric data in Europe.

The Automotive Test Point Analysis Utility allows designers to test intensity distributions against industry specifications, such as Society of Automotive Engineers (SAE) standards, as well as user-defined specifications. The utility has been enhanced to include many specifications from the Inland Transport Division of the United Nations Economic Commission for Europe (ECE).

New Ray Report and Plot Utilities

Added to the LightTools utility library are the Ray Report utility, which allows users to visualize ray data in easy-to-read, customizable formats, and the Plot utility, which allows users to plot multiple raster charts and line charts side by side and provides additional data analysis features such as mesh apertures and data-differencing for receiver mesh data, user grids, IES files and user data files.

Enhanced Modeling of Optical Surface Scattering

LightTools models now support Bidirectional Scattering Distribution Function (BSDF) files generated by Synopsys\’ RSoft Photonic Component Design Suite that contain scattering information for periodic optical structures, such as subwavelength diffractive surface gratings. This facilitates the design and analysis of lighting systems with small-feature, diffractive optical structures such as nano-structured LEDs.
