Hi All- just wanted to share this demo that we put together for a recent presentation on air quality forecasting and immersive technology. Figmin-XR demo

Cheers

Nice, can you share how the paraview rendering is done and recovered ?

Hi Mathieu,

A quick response-

We built a Paraview model of air pollution for an extreme bushfire smoke event in Australia using output from our AQFx smoke forecasting system. A more complete view of the Paraview render for this event is available on YouTube. For the Figmin XR demo, we took one frame of the Paraview render and output this in glf format. The file size had to be substantially reduced to be compatible with Figmin, and so we did some triangle decimation in Blender. We also did some manual annotations in FigminXR to add things like fire operations aircraft, smoke exposure characterisation and so forth. You can see some of this in virtual_scc_raw.mp4 . Also, we added a panel of SBS output from Paraview, and this pops nicely in the Figmin XR environment.

So everything was a little kludged together for the demo, however-

  • we have modified the AQFx daily output to be more compatible with the ParaView NetCDF file reader;

  • the Blender step can be eliminated by doing the decimation in Paraview;

  • we could easily incorporate a script to do the Paraview rendering within the AQFx daily operation loop;

  • FigMin XR is shortly to get a scripting capability, and I’ve been told that this would enable us to download aircraft movements in real time (amongst many other things); and I guess progressive hourly updates of the glb files for the situation table.

Happy to provide our data sets and a .pvsm file if this is helpful, also the FigMin setup.

Finally, we’ve been dabbling in the use of pancake and immersive tech for interpreting AQ forecasts for a while- although very low key and with just small amounts of funding.

All the best,
Martin
