A simple demo to show interactive visualization in VR of a CFD simulation. The dataset in this case is from the OpenFOAM motorbike tutorial and consists of a steady-state solution that includes turbulence.

In VR the user can

  • trace a set of streamlines from a chosen point
  • inspect a slice of the simulation domain
  • change the mesh representation
  • change the scale of the model for easy inspection in both life-size scale and much smaller “table-top” view

The streamline tracing is done live through VTK. Rendering and VR controls are handled with PyOpenGL and pyopenvr.
