Simulation Maximum Increased to 1000 Billion Rays

With one trillion rays now available for a simulation, the sampling limits are lifted for virtually all Monte Carlo simulations. This significantly expanded ray trace limit allows you to achieve better results for stray light analysis and luminance calculations.

Scatter Aiming Capability Extended to Measured BSDF Surfaces

The aim area feature in LightTools has been extended to support measured BSDF surfaces. This capability can significantly improve the efficiency and accuracy of stray light analysis in systems with measured BSDF surfaces.

Curved Surfaces Support in the Backlight Pattern Optimization Utility

With LightTools unique Backlight Pattern Optimization utility, you can now design display systems with curved panel shapes. With this capability, your design can conform to a dashboard, rotate about a user’s field of view, or conform to novel consumer electronic shapes, all with high spatial uniformity.

Usability Enhancements

More than a dozen modifications were made to improve usability in this release, including options for zooming in on a specific surface or object, to apply optical properties or align other components, for example. New layout options save the size and arrangement of your LightTools views, which enables you to restore a model with views positioned as they were when you closed it; you can also take a snapshot of a layout that can later be restored, which can be helpful when you share the model with a colleague as you collaborate on a design.

Improvements to the Utility Library

Improvements were made to the Light Guide Designer, Backlight Pattern Optimizer (BPO) utility, Parameter Analyzer, and Ray Path Analyzer, and the Surface Selection utility was added under Geometry utilities.

Enhancements to LightTools Libraries

Updates were made to the Example Model Library, the Materials Library, the Optical Properties Library, and the Glass Catalogs.
