Other Products

Beside VTD (but also available in combination with it), we provide a series of additional tools for automotive simulation purposes:

  • Road Designer (click for details...)
    Design your road networks in full detail with unlimited numbers of lanes, complex intersections, comprehensive signs and signaling etc. Generate your logics and graphics data consistently from a single source. All logics data is exported compliant to the OpenDRIVE format. The export of the graphics data may be customized.
    • Database Design
      • From scratch
      • Tile-based (extensive libraries available)
      • Country-specific signs and signas (e.g. D, A, I, CH, F, USA, China)
    • Data Import
      • OpenDRIVE
      • OpenStreetMap
      • GPS plots
      • custom formats
    • Data Export
      • OpenDRIVE
      • OpenSceneGraph formats (e.g. .ive)
    • Fully OpenDRIVE compliant

  • Sound Simulation
    • Ego sound
      • engine, road contact, wind
      • depending on RPM, load, road surface
      • custom engines may be implemented
    • Traffic sound
      • various vehicle types
      • Doppler effect
    • Custom sounds
      • custom sound samples
      • single or continuous mode

  • OpenDRIVE Manager (SDK) (click for details...)
    Load and evaluate OpenDRIVE data files within your own applications. Perfectly suited for real-time applications. This library is available for Linux and Windows operating systems (32bit and 64bit). An obfuscated source code version is available for non-standard targets which require local compilation.

  • OpenDRIVE Gateway
    Contact point calculation for high frequency operation (e.g. 1kHz). Technically, the gateway wraps the OpenDRIVE Manager and provides a network interface for querying contact point information. It integrates seamlessly with VTD and is an alternative for custom vehicle dynamics modules to the full integration of the OpenDRIVE Manager library.

  • Visual Databases

    Custom designed visual databases are one of our origins. We have developed a series of tools around this task, so that we are today able to generate visual (and the corresponding logical) databases from

    • Measured data, including surface data (OpenCRG)
    • Paper Maps
    • Videos
    • Custom Data

  • Driving Simulators

    Although we are mainly focusing on software issues, we are also capable of providing complete fixed-base simulator solutions consisting of

    • Simulator Mockup
    • Projection System
    • Computer Racks
    • Integration Services
Railroad and Tram

VTD icon VIRES Virtual Test Drive

As for the automotive business, we are also using our VTD tool-suite for the railroad industry. All of the components listed above in the automotive section are also available for railroad applications, however taking care of the railroad-specific requirements like

  • Vehicle Dynamics
  • Signaling
  • Track Design

Our Road Designer (here called "Railroad Designer") is capable or exporting data according to the RailML standard.

By combining both worlds in one tool, we are able to provide also simulation solutions for tram environments where railroad and automotive entities even share common traffic space.

Aerospace

Certainly our smallest division with a focus mainly on helicopter flight simulation but nonetheless of great importance to us. For aerospace industries, we provide the following products and services:

  • Image Generators
  • Visual Databases
  • Flight Simulators
  • Custom Solutions
