LucidShape and LucidDrive: What's New

LucidDrive Updates

The LucidDrive AFS Masking PixelLight feature simulates pixel light technology by detecting oncoming and overtaking traffic, calculating bounding boxes and creating user-definable shadow masks in headlamp light distributions. These functions are useful for automotive designers in both development and testing phases of pixel light systems.


LucidShape CAA V5 Based Updates

LucidShape CAA V5 Based 2017.09 includes the following new features for optical simulations and analyses of automotive lighting products in the CATIA V5 environment:

  • LucidShape CAA V5 Based supports CATIA Version 5 R24, R25, or R26 with Service Pack 3.


  • Simulation Configurations. You can now configure simulations so that they include only the objects that are relevant for the respective simulation and analysis. You create a simulation configuration by specifying the sources, actors and sensors that will participate in a simulation; objects that are not included in the configuration are ignored and do not affect the ray trace results. This new capability makes it easy to analyze different lighting functions, such as low beams, high beams, and signal lighting functions, without having to manually reconfigure the model between simulations.


  • Simulation in Batch Mode. This release includes the ability to run all active simulations that are defined in the active model document. This enables you to schedule multiple simulations to run one after the other, without the need for intermediate input.


  • Fixed Random Seed for Simulation. You now have the option to maintain a fixed random seed for simulations, which enables you to rerun simulations while maintaining the same results. This functionality also works after saving, closing, and restoring a model, in the same session or a new session of LucidShape CAA.


  • Ray History Sensor for Candela Sensor. Enhancements to the Ray History Sensor for the Candela Sensor include the ability to restore ray paths without having to rerun the simulation after save and restore operations, the display of Ray History Sensors results as a sub-node under the simulation results in the Specification Tree for improved model organization, and the ability to use multiple Ray History Sensors in the same model.


  • Ray History Sensor for Luminance Camera Sensor. Previously, the Ray History Sensor functionality in LucidShape CAA was limited to the Candela Sensor. In this release, we introduce Ray History Sensor functionality for the Luminance Camera Sensor. This functionality enables you to restore ray paths that correspond to a specific region on a luminance camera image.


  • Light Guide Design Module. In this release, the Light Guide Designer (previously released as a beta feature) has been renamed the Light Guide Design Module and requires a separate license. The Light Guide Design Module includes the following new capabilities:
    • New shape types that provide more versatile styling opportunities. New shapes include: circle with flat, partial ellipse, square, rectangle, keyhole, and user profile.
    • Support for scaling and rotated profiles
    • Inward and outward oriented prism option
    • Enhanced exit surface construction
    • Dual optimization mode and optimization support for tapered light guides
    • Die pull direction support

LucidShape Updates

LucidShape version 2017.03 includes the following new features for automotive lighting design:

  • Automotive headlight analysis based on the U.S. Insurance Institute for Highway Safety (IIHS) headlight test guidelines. This allows designers to perform these types of analysis: Illuminance-based visibility range testing, glare test for oncoming traffic, and overall headlight results, ranging from good to poor.

  • The new MacroFocal Torus Optic tool, which creates pillow optics and cylinder flutes for decorative styling. It is particularly useful for designing signal lights and tail lights, but can also be used to create and adjust any pillowed surface on a grid. The Torus Optic tool works with the proprietary algorithms in LucidShape software to automatically calculate and construct optical surfaces based on user-defined illuminance and intensity patterns.

  • Improved organization and usability of the UV Data Properties dialog box. It has been rearranged into four sections to: ranges and presets, data display, overlay, and color tone mapping. In addition, the UV Data Properties dialog box now includes the ability to define presets for display properties and custom isolines.
