Took 6 hours to calculate on an academia GPU setup. | | Edit: He also says it's full engineering accuracy, not cheap CGI | CFD that only has to look plausible. You could extract pressures, | forces from the surfaces and use it for analysis. He's done | extensive validation for his academic work. | 101008 wrote: | I hope advances in this field would help to reduce turbulence | in passangers flights. | blevin wrote: | Project code here: https://github.com/ProjectPhysX/FluidX3D | atoav wrote: | One of my favourite wind implementations (both visually and from | a game design standpoint) has been the winds in Ghost of | Tsushima, there is a interesting talk/video with the developer | who worked on it. | https://www.gamedeveloper.com/api/redirects?to=/gdc2021 | | The way they decided to use the wind to guide players to the next | point of interest is also an interesting concept in the minimap- | plagued open world genre. | Folcon wrote: | Slides of talk being referenced[0], not managed to find the | video yet. | | -[0]: https://www.gdcvault.com/play/1027124/Blowing-from-the- | West-... | hwers wrote: | This is extremely well written | mhh__ wrote: | LBM is fascinating, an informatively different route to a fluid | solver | metabagel wrote: | Has anyone done this for fabric sails on a sailboat? | irsagent wrote: ___________________________________________________________________ (page generated 2022-10-11 23:00 UTC)
