Extracting mesh from settled fluid

[josemendez]

Hi Jose, I did a preliminary CPU implementation (particle ellipsoids -> SDF -> SurfaceNet). Video demo:



A GPU implementation is needed to push the performance further at higher resolutions and particle count. But right now, I think I need to sort out some oddities with the ellipsoids positions. Some ellipsoids in my mesh are displaced differently than your billboard version:



I'm getting and using the positions and anisotropies from ObiSolver. And most of them do align 1:1 to your billboard rendering. But some are just displaced way out there. I dug into your ellipsoids rendering code but can't seem to find the reason. Any pointers on this will be much appreciated. Thanks!

Hi,

Great work! it's looking good

Read from the solver.renderablePositions array instead of solver.positions. That should give you particle positions post- temporal/spatial smoothing.

Let me know if you're already doing it this way, there might be a different reason for this.
