The term guide makes sense on it's own in this context.

These attributes checked for any baked / baking
since this is a common test that was performed in layout code.
Also follow our naming convention - using an 'is_/has_' prefix
in this case since "cache_baked_data" reads as if it's used to access
the baked data.

Create/Destroy are more commonly paired terms in BLI/BKE API's.

Fixed sized strings are always initialized & this is not done
elsewhere before calling BLI_path_join.
Remove since it's not needed and makes it read as if the function
might not initialize the output argument.

gpu_draw.c had generic sounding utility functions which were specific
to smoke drawing.
Split into it's own file so the functionality is clearly separated.

Also remove dead code which checked for SPACE_TIME.

This had already been removed for all source files,
recent patches re-introduced them.

Allows enabling debug prints in this file easily,
differentiates it from code which has been disabled for other reasons.
Also remove unused DEBUG_TIME.

When the option was enabled, the onion was not render as expected.

The particle system needs some tweaks so that it can be used for particles created in Mantaflow (i.e. to read both FLIP and secondary particles from Mantaflow).

Cycles needs some smaller updates so that the up-res smoke wavelet noise and the liquid mesh speed vector export work correctly.

A collection of smaller changes that are required in the /blender/source files. A lot of them are also due to variable renaming.

Probably the most significant changes are in smoke.c.
New functionality includes:
- support for adative time steps (substeps)
- write flow objects to grid structure so that Mantaflow can generate levelsets
- no more distinction between FLUID_3D and WTURBULENCE objects. Everthing that communicates with Mantaflow now lives in a FLUID object.

All new simulation parameters need to be registered in the RNA. Especially for liquids a lot of new ones need to be added.

Similarly to physics_fluid.c (in same directory) which handled the baking process for Elbeem, there is now physics_manta.c which handles it for Mantaflow.
There are two types of jobs: one for baking and another for freeing. The generic jobs will be used to bake / free specific parts of the simulation (e.g. bake mesh, free particles, etc.).
The jobs are only being used in the "modular" cache mode where the simulation has to be baked in parts.

With Mantaflow the current smoke modifier UI will accommodate both smoke and liquids.
In addition, there is now an option for Mantaflow liquids in the quick effects section ("Quick Liquid").

Files from /intern/mantaflow handle the communication between core Blender code and Mantaflow itself. It's the bridge to communicate with Mantas Python functions.
Code from /intern/mantaflow/intern/strings/ is pure Manta code and would likely need less attention in the review.

Includes preprocessed Mantaflow source files for both OpenMP and TBB (if OpenMP is not present, TBB files will be used instead).
These files come directly from the Mantaflow repository. Future updates to the core fluid solver will take place by updating the files.

Previously this limit was rather high, but with UDIMs it's fairly easy
to reach this many images. Even though this exceeds the texture limit
on most hardware as far as I can tell, it should at least not crash.
The old code uses a fixed array which overflows eventually, this fix
replaces the array with a GSet.

The ImageTextureNode incorrectly used the tile slot encoding for box-
mapped textures as well. Since box-mapping always generates UVs that
lie in the 1001 tile, there's no need to support tiles here.
|
|
This was caused by a call to paint_2d_bucket_fill that I missed in the
UDIM changes.
Now, this feature does not only not crash, but it even works with tiled
images!

- Use the clip mask context menu for the image editor.
- Remove redundant CLIP_MT_mask_handle_type_menu.
- Remove "Add" items (was only in image mask context menu)
as the convention is not to include these in the context menu.
|
|
This file only defined a single mask menu, move the definition
along-side the other mask menus.
|
|
The tools passed to _tools_flatten, _tools_flatten_with_tool_index
already have dynamic tool items expanded, so there is no need to check
for callable tool items.

The code checked for the presence of more than one tile before
substituting the tile number into the filename, so if a one-tile
UDIM was used (or all but one tile were culled), the substitution
was skipped and as a result the file was not found.
With this change, the code explicitly tracks whether substitution
is required, avoiding this problem.
This also fixes another problem: The Environment texture never
does substitution since it doesn't support UDIMs, but before the
syncing code still inserted the placeholder into the filename if the
user selected a tiled background image.
