Animations with firefly #146

Open Boorhin opened 2 years ago

Boorhin commented 2 years ago

Hi, I am looking into firefly at the moment and I am under the impression we could potentially display particle data that evolve through time. Is that possible? I have a large dataset of particles that evolve in space and time and I am looking into ways of visualising it. Thanks

The feature you may be thinking of (that currently exists) is the "Animate Velocities" checkbox, which extrapolates particle positions along their velocity vectors (see below). I have thought about how we would implement particle data that evolves through time (by interpolating between keyframe values for the coordinates, velocities, scalar fields, etc.) and I think I know how I would go about doing it but I probably won't be able to do add the feature for at least another couple of months.

Let's keep this issue open so I can let you know when I get around to it (and keep it officially on the roadmap!).

Yes that's what I saw My dataset contains the position of said particles through time so that would be a little different but that's the idea. It is more for oceanographic applications Thanks for looking into it!
