Synopsys releases LucidShape & LucidDrive Version 2.1

In addition, Synopsys LucidDrive version 2.1 introduces key enhancements for simulating vehicle headlamps under nighttime driving conditions. For example, LucidDrive simulations have been expanded to include matrix beam headlamps, dimming and swiveling headlamps and vehicle geometry for left-hand traffic conditions.

"With updates to human eye vision and Adaptive Front-Lighting System simulations, both LucidShape and LucidDrive continue to support advances in automotive lighting design," said George Bayz, Vice President and General Manager, Synopsys' Optical Solutions Group. "The latest releases also help users quickly translate their ideas into complete designs with ease-of-use improvements to simplify model setup and refinement."

LucidShape version 2.1 includes the following new features for automotive lighting design:

• The TreeView, which provides a hierarchical display of LucidShape model data, has been upgraded for faster performance and improved large model handling.
• The Visualize Module, which delivers high-speed photorealistic images of an automotive lighting system's lit appearance, has a simplified user interface that includes new presets and range controls to quickly fine tune results.
• The Visualize Module Human Eye Vision Image (HEVI) interface includes new options for simulating and solving glare effects. Users have the option to choose from different glare models, including Vos and Holladay and to include information that enables glare analysis as a function of angle and observer age.
• Expanded 2D and 3D measured Bidirectional Scatter Distribution Function (BSDF) material libraries for high-accuracy modeling of surface scattering for materials used in automotive lighting.

"The introduction of Vos and Holladay glare functionality in LucidShape is another big step forward in improving photorealism of simulated images," said Jason Smith, optical engineering manager at Grakon, LLC. "The additional TreeView updates substantially increase navigation speed, especially in larger models."

LucidDrive version 2.1 includes the following new features for evaluating beam patterns of vehicle headlamps under nighttime driving conditions:

• New matrix beam Adaptive Front-Lighting System (AFS) script with prepared solutions for six and eight lighting elements
• New options for defining color temperature and chromatic adaption to enhance the realism of LucidDrive's lighting simulations
• New vehicle geometry for simulating nighttime driving conditions for left-hand traffic
• Improved road libraries for fast preview and selection of road scenes
• New scripts to enable MATLAB simulation of dimming and swiveling headlamps
