Playback / replay visualiser

[ptheywood]

Being able to visualise previously run visualisations would be useful for running simulations remotely or similar.

This should be able to share a common code base with models and with the majority of visualisation code, only requiring a different way to pass data to the intanced rendering.

I.e.

• Launch the flamegpu executable with a different runtime argument, specifying a collection of xml (or other format) files for different iterations.
• Load data from those files into memory, and push to a gpu buffer for instanced rendering.
• Extra keybindings for stepping through the simulation (forwards and backwards) + playback.

Potentially this could be implemented to also work on systems without an NVIDIA GPU.

This is very low priority however.

Wouldn't be too much work to fork the main Visualiser class in vis lib, to have a version that loads from file (hence removing the nvidia dependency).

Would just require testing shaders on intel/amd, to check theyre properly valid.

That's what I was thinking, but yeah testing shader compilation on amd might be a challenge for us.

Could probably ask a favour of Petterson, I think he might have AMD desktop.
