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.
