IPSI™

IPSI (Interactive Physics Simulation Interface) is a software library for physical simulation with force-feedback developed by Haption in collaboration with CEA-List.
IPSI is used in the implementation of:

  • Interactive Fitting for Catia (IFC)
  • Interactive Physic Pack (IPP) for Virtools

IPSI is a physics engine and a comprehensive solution to stability problems, model complexity and precision issues in case of industrial applications.

Specificity
  • Distributed architecture (client/server) based on the ONC RPC (open standard)
  • Multi operating system for the client and the server: Microsoft Windows™, Linux
  • Scenes composed of rigid bodies
  • Simulation of simple kinematics chains (no closed-loop kinematics)
  • Static integration (no inertial forces)
  • 6-dof force-feedback output
  • Compatibility with all the product line Virtuose™
  • Degraded operation without force feedback for 6D mouse (product line 3DConnexion©)
  • Compatibility with optical tracking systems from ART©

IPSI™ Server

The IPSI server integrates software modules for collision detection (LMD++) and for simulation of movement (GVM) developed by the CEA-List.
It also integrates the software library for collision detection VPS™ (Voxmap PointShell) developed by BOEING/Phantom Works.

IPSI™ API - C++ library of functions for:
  • Connecting to the IPSI server locally or over the network
  • Loading 3D objects into the scene
  • Selecting interaction-enabled objects
  • Creating simple kinematics constraints (prismatic, plane, pivot, etc...) and connecting those to objects in the scene
  • Associating interaction devices to objects in the scene
  • Starting/stopping an interactive simulation
  • Updating the position of objects in the scene for visualization
