Proof of Concept: Realtime Fluid Simulation in VR

I am happy to share a little insight into a project I was working on last year. In collaboration with Dirk Hartmann and Theodoros Papadopoulos from Siemens Corporate Technology I implemented two VR applications. Both apps utilize realtime fluid simulation to interactively simulate the behavior of smoke.

I can’t talk about the details here, but I would like to share a post and a video on LinkedIn. The video shows one of the applications and gives a good impression on the interactive smoke simulation.

What the video doesn’t show is the simulation of air within the rooms. It looks like the fan is simply applying forces to the smoke particles, but actually the whole room is filled with invisible air fluid, which makes the simulation much more accurate.
