LucidShape: Innovative Automotive Lighting Design

LucidShape CAA V5 Based

LucidShape is the most powerful and advanced computer aided lighting (CAL) design software for automotive lighting design tasks. With dedicated algorithms optimized for automotive applications, LucidShape facilitates the design of automotive forward, rear and signal lighting, and reflectors.

LucidShape New Features

LucidShape version 2018.06 includes the following new features for automotive lighting design:

  • New Luminance Region Analysis
    LucidShape’s Luminance Camera Sensor feature performs rapid, high-accuracy luminance calculations and generates luminance images at multiple viewing directions for analyzing lit images of light guides, tail lights, reverse lights, stop lights, turn signal lights, and retro-reflectors. Now included with the Luminance Camera Sensor is a ray history sensor feature that enables designers to restore ray paths that correspond to a specified region on the luminance camera image. The new capability facilitates efficient troubleshooting of signal lighting optical systems by correlating regions in the luminance image with specific ray paths and optical surfaces. This significantly reduces the number of design iterations needed to achieve lit appearance requirements and regulatory compliance.

  • Fixed Random Seed Option for Simulations
    For Monte Carlo ray tracing simulations, it is now possible to set a fixed random seed, which deactivates the randomization of ray creation and interaction. This makes it possible to replicate the starting conditions for all rays as well as the random events along the ray paths (e.g., scatter, Fresnel reflections) when you repeat a simulation using the same parameters. By causing the statistical noise to be the same between two simulations, this enhancement allows changes to the lighting model to have a stronger impact with a smaller number of rays.

Key Capabilities

LucidShape FunGeo

LucidShape FunGeo

LucidShape FunGeo is the ultimate tool to help you quickly and easily create reflector or lens geometry. It leverages proprietary algorithms that automatically calculate and construct optical geometries based on user-defined illuminance and intensity patterns. This unique, functional approach gives you the freedom to focus on overall design objectives rather than the implementation details of complex optical components.

LucidShape FunGeo includes modules to:

  • Create reflectors for beam pattern with a sharp cutoff line
  • Create profiled reflectors or refractors with an particular beam pattern
  • Create automotive projector lamps
  • Approximate or interpolate curves and surfaces
  • Create surfaces with lighting or optical features
  • Compensate ray deviations from curved lens surfaces
GPUTrace™

GPUTrace™

Accelerate LucidShape illumination simulations with GPUTrace and experience a quantum leap in speed! LucidShape is the first optical simulation software to take advantage of graphics processing unit (GPU) computing to deliver simulation speed increases by orders of magnitude compared to multithreading capabilities.

Visualize Module

Visualize Module

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. This is particularly important for evaluating automotive components such as turn signals and brake lights. 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 includes these key capabilities:

  • Supports environment sources for the integration of 360-degree, high-dynamic range (HDR) photographic environments into photorealistic visualizations. Includes all physical and optical properties for an immersive, accurate rendering of a lighting scene.
  • 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.
  • Harnesses LucidShape's GPUTrace™ solution to give designers the flexibility to rapidly evaluate their models at any point in the design process.
LucidCOM

LucidCOM

LucidCOM is LucidShape's interface to Microsoft COM, which allows you to develop custom solutions to automate tasks and leverage other COM-enabled tools, such as Rhino 3D or CATIA.

With LucidCOM, you are able to instruct CATIA to perform special tasks, such as opening and saving a file or drawing a line. You can also program Visual Basic (VBA) macros in CATIA to instruct LucidShape to perform calculations with specified geometry. LucidCOM is supported by the script language LucidShell, therefore you don't need VBA scripts in LucidShape to use COM in other programs. You can even create your own LucidShape plugin with your own C++ functions.

LucidShell

LucidShell, LucidShape's script interpreter, can be used to perform a wide variety of design tasks through a script procedure written in a C/C++ -like language.

You can program model geometry, optical surface properties, ray tracing, dialog boxes, and even your own customized menu. Complex geometry such as light pipes or prisms may be more easily defined in a shell script than in LucidStudio. Your own programs can be integrated with the LucidShape user interface and display as dialogs or menu items. You can easily customize your LucidStudio's user interface for your individual needs in your daily project work.

LucidObject

The foundation of LucidShell is its versatile toolbox: the LucidObject library. Objects can be created through dialog boxes in LucidStudio or instanced by function calls in LucidShell to build up the Digital Mock Up (DMU). The power of LucidShape originates from this library, which is continually expanded. The toolbox holds a rich set of different object types to define geometry, material, media, motion, simulation, tasks, behavior, interactions and utility operations.
