Includes update for OpenVDB file IO, i.e. fixes an issue with
compression flag combination that resulted in random segfaults.
Other changes: Cleanup and formatting.
|
|
This updates fixes the following issues (critical for 2.92):
- Issue that prevented dense 'int' grids from being exported (incorrect clip value)
- Issue with particles outside out of domain bounds (position between -1 and 0) not being deleted
|
|
Includes improvements for the file IO. Namely, more meta data will be written from now on.
This change is required to prevent IO issues (e.g. T84649) that arised through the use of sparse grids caching (introduced in 2.92).

Fixes issue where files would not be written when 'resumable' option was checked.

This update introduces two improvements from the Mantaflow repository:
(1) Improved particle sampling:
- Liquid and secondary particles are sampled more predictably. With all parameters being equal, baked particles will be computed at the exact same position during every bake.
- Before, this was not guaranteed.
(2) Sparse grid caching:
- While saving grid data to disk, grids will from now on be saved in a sparse structure whenever possible (e.g. density, flame but not levelsets).
- With the sparse optimization grid cells with a value under the 'Empty Space' value (already present in domain settings) will not be cached.
- The main benefits of this optimization are: Smaller cache sizes and faster playback of simulation data in the viewport.
- This optimization works 'out-of-the-box'. There is no option in the UI to enable it.
- For now, only smoke simulation grids will take advantage of this optimization.

Updated files includes:
- Fix for smoke / fire emission from particles
- Custom precision for liquid particles when saving in OpenVDB format
|
|
Among code cleanups, this update includes a new flood-fill helper function for levelsets.

Kudos to brecht for noticing the issue

This updated set of Mantaflow files includes the improved OpenVDB file IO. With this update it is finally possible to store multiple grids per file. It is also possible to save particle systems and particle data to OpenVDB files.
