LUCIDSHAPE : Automotive Exterior Lighting Design Software

LucidShape software is used for the design and real-time simulation of automotive forward, rear, and signal lighting.

The LucidShape product family provides a complete set of design and analysis tools for automotive lighting. With dedicated algorithms optimized for automotive applications, LucidShape facilitates the design of automotive forward, rear and signal lighting and reflectors.

LucidShape is the most powerful and advanced 3D system for computer aided designing of lighting design tasks. It’s friendly and very extensive user-interface enables engineers from all over the world to create all kinds of reflectors and other lighting applications in very short time. You can create the geometry in 3D with high-innovative Functional Geometry Capabilities (FunGeo) or import almost every CAD program available (e.g. CATIA, Rhino, etc.) via data exchange.

New Features in LucidShape and LucidDrive Version 2017.03

LucidShape: IIHS Headlight Test

The U.S. Insurance Institute for Highway Safety (IIHS) headlight test provides the following types of analysis:

  • Glare test for oncoming traffic
  • Overall headlight results, ranging from good to poor

LucidShape: MacroFocal Torus Optic Tool

The new MacroFocal Torus Optic tool creates pillow optics and cylinder flutes for decorative styling. It is particularly useful for designing signal lights and taillights, but can also be used to create and adjust any pillowed surface on a grid.
LucidShape: UV Data Properties Dialog Box Enhancements

The UV Data Properties dialog box has been rearranged into four sections to improve its organization and usability:

  • Ranges and presets
  • Data display
  • Overlay
  • Color tone mapping

In addition, the UV Data Properties dialog box now includes the ability to define presets for display properties and custom isolines.


LucidShape CAA V5 Based

LucidShape CAA V5 Based is an interactive tool that allows designers to perform optical simulations and analyses of automotive lighting products within the CATIA V5 environment. Because of the tool’s complete integration within CATIA V5, designers who are familiar with CATIA can easily leverage LucidShape’s powerful features to produce, with a minimal learning curve, automotive lighting products that meet performance, styling, visual branding and regulatory requirements.

Key Capabilities
Light Guide Design Module
The Light Guide Design Module helps automate the construction, analysis and optimization of light pipes and their extraction features to improve light output.

Geometry Creation and Import
To build your automotive lighting model in LucidShape CAA V5 Based, you can use CATIA-generated geometry or import geometry created in LucidShape. You can then choose various sources and sensors; assign, create and edit materials and media using a materials library; and define simulation settings and analysis preferences.

  • Sources: Point, plane, cylinder, and ray file
  • Sensors: Candela, luminance camera, ray file, ray history
  • All LucidShape actor materials are supported and the material definitions are organized in a material library
  • Supports CATIA V5 workbenches so you can customize your workflows to speed up the modeling process


Easy Visual Navigation of Complex Models
Model navigation and management is highly efficient with the software’s specification tree structure, which keeps all automotive lighting components organized and accessible from a single location. For example, products have a tree section that shows and allows the editing of all LucidShape-specific elements in an entire product assembly.

Rapid Design Verification
The software can rapidly and accurately ray trace part-level models or product-level assemblies using both tessellated and NURBS simulation methods, for the most comprehensive CATIA-based optical simulations currently available. You can run a simulation on one part while you continue to work on another part in the same project.

The software also supports multi-core processing and GPU ray tracing (for tessellated mode only) to further accelerate simulations.

Full Suite of Analysis Tools
The software delivers a comprehensive spectrum of UV data analysis tools, as well as bird’s eye and driver’s views. A large set of test point standards are included to ensure that your system meets both industry regulations and company specifications. Specific analysis tools include:

  • Test tables (ECE, SAE, JIS, user defined)
  • Special views (bird’s eye view, driver’s view)
  • Variety of UV data operations (scale, shift, rotate, etc.)
  • Planar Lux Sensor for quantitative analysis of near-field illuminance
  • Luminance Camera Sensor for rapid, high-accuracy luminance images at multiple viewing directions. Includes ray history sensor feature to restore ray paths that correspond to region selections on specific luminance camera images; this functionality allows you to efficiently troubleshoot signal lighting optical systems, by correlating regions in the luminance image with specific ray paths, and thereby the respective optical surfaces. As a result, the number of design iterations that are needed to meet lit appearance, in addition to regulation compliance, can be significantly reduced

You can easily export your model to LucidShape to perform other tasks, including simulation and visualization of lit and unlit appearance.


The LucidDrive tool provides night driving simulations that generate nearly photorealistic lighting scenes in real time, which allows designers to quickly and accurately evaluate beam patterns of vehicle headlamps prior to expensive fabrication and testing.

LucidDrive is a standalone night driving simulation tool. It makes use of the latest modern graphics hardware technology to show near-photorealistic lighting scenes in real time. The primary function of LucidDrive is to evaluate beam patterns of vehicle headlamps under simulated, realistic conditions. It is an ideal software tool to provide virtual reality simulation prior to expensive fabrication and testing.
