Automotive lighting design software models perception by human eye

April 02, 2015 // By Graham Prophet
Version 2.0 of Synopsys’ LucidShape lighting design package enables more accurate model creation and contains a diagnostic tool for evaluating how a lighting system will be perceived by the human eye. This is particularly important for evaluating automotive components such as turn signals and brake lights.

The LucidShape Visualize Module provides photorealistic visualisations that help designers troubleshoot and improve automotive lighting designs at any stage in the development process. Its Ray Data Viewer allows designers to preview vendor light sources before building model geometry, and its Light Pipe Tool enables fast, robust creation of complete light pipe geometry. An expanded material library with measured BSDF data delivers unsurpassed accuracy for modelling automotive lighting surfaces.

LucidShape’s Visualize Module delivers high speed photorealistic images of an automotive lighting system’s lit appearance, which demonstrate luminance effects when light sources in a model are illuminated. Because the Visualize Module depicts all interactions between system geometry and light sources, it provides designers with a physically correct diagnostic tool for evaluating how a lighting system will be perceived by the human eye. The Visualize Module is a fast, reliable engineering tool that enables designers to perform design checks and make improvements early and often in the product development process.

The Visualize Module supports environment sources for the integration of 360-degree, high dynamic range (HDR) photographic environments into photorealistic visualisations and includes all physical and optical properties for an immersive, accurate rendering of a lighting scene. It combines LucidShape’s luminance camera and backward ray tracing to perform rapid, high accuracy luminance calculations and generate photorealistic images at multiple angles and viewing directions, and harnesses LucidShape’s GPUtrace solution, which uses graphics processing unit (GPU) computing to accelerate illumination simulations by orders of magnitude compared to multithreading capabilities. The speed of the Visualize Module’s simulations gives designers the flexibility to rapidly evaluate their models at any point in the design process.

“The LucidShape Visualize Module is a powerful engineering tool that doesn’t just render a design—it provides a virtual prototype that allows automotive lighting designers to quickly pinpoint aspects of a model that can be improved to generate the best possible performance,” said George Bayz, vice president and general manager of Synopsys’ Optical Solutions Group. “The module reduces the need for costly and lengthy physical prototyping.”
