INTERACT rely on the powerful Unity RT3D engine. Unity engine provides state-of-the-art 3D graphics capabilities. This popular platform also permits user customization, either by relying on additional packages or by developing your own. User friendly interface eases the tool adoption, from beginner to power-user. Undo, redo and iterate fast. Thanks to Pixyz add-on, you can import native CAD files seamlessly in your scene. 

Feel at home with Interact, even with no previous knowledge of Unity. Setup kinematic link like in a CAD software: Interact can automatically recognize shapes and edges making it easy to precisely position and orient them. Navigate in the full CAD hierarchy, group, or merge parts to define which parts will move together.  

Reproduce complex mechanical systems. Combine joints together. Define constraints limits. Visualize complete kinematic graph to show every mechanical constraint immediately. Using reduced-coordinates by default, constraints will remains stable even with high forces. 

Accurate collision detection on industrial models. Work on convex and concave parts, even with a large number of triangles. Avoid costly pre-process to concentrate on simulation results. Customize gap clearance to ensure fitting. Visualize collision points. Setup friction and compliance. 

Grab, push, pull objects in your virtual scenes. Ensure hand accessibility. Use finger tracking with Manus or Leap motion to improve interaction fidelity. Match virtual and physical props using Vive trackers. 

Simulate cable deformations using a real time finite element model for cables. Ensure cable bend radius specifications and plan your cable routing accordingly. Recognize cable shapes to easily define initial properties. 

Use full body motion tracking in virtual reality to improve workspace ergonomy. Compute RULA score to spot musculo skeletal risks. 

Scenarize and define order for parts assembly. Snap parts when they are in position. Model maintenance and decommission processes to decrease Total Cost of Ownership. 

Push the realism to eleven using haptic force feedback. Interact is compatible with Virtuose device from Haption company and can compute collisions in a suitable time for force-feedback.  

Interact uses a dedicated collision detection engine based on signed distance field. 

Use your simulation on CAVE. Support optical tracking provided by ART or Optitrack, compute appropriate stereoscopic views. Deploy on a cluster.
