Add 'missing' bpy code from BKE_libblock_free_ex(), now both functions
do exactly the same thing, only the later is less flexible (fewer
'exotic' behaviors supported, like handling IDs outside of bmain etc.).
Next step: nuke usages of BKE_libblock_free functions, makes no sense to
have twice the same code around!
The existing Add and Multiply blending modes have limited usability,
because the appropriate operation for meaningfully combining values
depends on the channel. This adds a new mode that chooses the operation
automatically based on property settings:
- Axis+Angle channels are summed, effectively averaging the
axis, but adding up the angle. Default is forced to 0.
- Quaternion channels use quaternion multiplication:
result = prev * value ^ influence
- Scale-like multiplicative channels use multiplication:
result = prev * (value / default) ^ influence
- Other channels use addition:
result = prev + (value - default) * influence
Inclusion of default in the computation ensures that combining
keyframed default values of properties keeps the default state,
even if the default isn't 0 or 1.
Strips with this mode can be keyframed normally in Tweak mode,
except that for quaternion rotation keyframing always inserts
all 4 channels, and the channel value sliders on the left side
of Graph/Action editors won't insert keys without Auto Key.
Quaternion keys are also automatically normalized.

Supporting a strip blending type that treats quaternions as a unit
also means being able to adjust all sub-channels as a unit when
inserting keyframes. This requires refactoring keyframe insertion
code to retrieve array property values for all channels at once,
before iterating over the indices being inserted.
Allows users to select a font for text strips in the video sequence editor.

When editing an action without a strip, or tweaking a strip without
time mapping enabled or supported, the extents of the virtual strip
can't be controlled and are purely derived from keys in the action.
Thus, cutting off evaluation of the action at these arbitrary points
gets in the way of observing the natural extrapolation of the F-Curves
and thus appears to be a mis-feature.
With this change non-mapped actions are evaluated with infinite
range, exactly like they are handled without NLA, unless extend
mode is set to Nothing.
The viewport stereoscopy support helpers are finally ported to 2.80.
We now can scale the camera and the "stereo cameras" will scale
in the viewport as well (unlike 2.7x).
At the moment I disabled the drawing of the camera frame when
stereo is selected and you are looking through the camera.
It is to be fixed later, but for now it draws the border wrong.
In 2.79 this was not a problem because the camera frame was drawn
afterwards as a hack.
Viewport > Stereoscopy:
* Cameras
* Convergence plane
* Convergence plane alpha
* Stereoscopy volume
* Stereoscopy volume alpha
Not sure exactly why this happened for 'apply as shape' and not in other
cases (did not took time to fully trace what happens there). But in any
case, `BKE_key_evaluate_object_ex()` can be called from a fair amount of
places, including during depsgraph evaluation, so setting back key's
owner here is plain wrong in CoW era.
More like a band-aid than anything else really, that code is horribly
weak and need to be fully re-written at some point (putting all those
temp data-blocks fully outside of bmain...). But for now should do.
Fix T60194: Sequencer cut loses animation data for the right strip.
Fixing the first also fixes the second. First attempt was delaying
uniquename check at a later step of cut process, after everything had
been duplicated. While this fixed first issue, second one became even
more proeminent (it become active for all strips, and not only
video/audio movie strips in meta's).
So instead, passing along the list of (new) sequences, so that duplicated
seqs can be put there immediately, before checking for unique names,
henceforth ensuring even strips inside meta's get properly handled.
This partially reverts commit bb98e83b99.
It fixed 'strips having same name' issue, but broke handling of
animation then. Need to find a better way to handle this.
This commit groups a set of new tools that were tested in grease pencil object branch before moving to master. We decide to do all the development in a separated branch because it could break master during days or weeks before the new tools were ready to deploy.
The commit includes:
- New Cutter tool to trim strokes and help cleaning up drawings.
- New set of constraints and guides to draw different types of shapes. All the credits for this development goes to Charlie Jolly (@charlie), thanks for your help!
- Segment selection mode to select strokes between intersections.
- New operator to change strokes cap mode.
- New option to display only keyframed frames. This option is very important when fill strokes with color.
- Multiple small fixes and tweaks.
Thanks to @pepeland and @mendio for their ideas, tests, reviews and support.
Note: Still pending the final icons for Cutter in Toolbar and Segment Selection in Topbar. @billreynish could help us here?
The overlay should now use the texture interpolation setting in material
mode.
In image mode, there is now a new button to let the user choose the texture
filter. The option is located in the Texture Slots popover and only shows
in Image mode.
TH_BACK was being used when drawing the 3D view even though
there was no way to set the color in the preferences.
The color was zero'd when moving to the new 2.8x theme.
Having both gradient and background colors was confusing,
especially having to use 'TH_HIGH_GRAD' for the 3D view, 'TH_BACK' for
other views.
Move the background color back to 'TH_BACK', 'TH_BACK_GRAD' is used
when gradients are enabled.
RNA is unchanged so presets don't need updating.
We should *never* prevent copying basic mesh CDLayers (vertices etc.),
that does not make sense.
I guess issue was not in old DM because geometry was duplicated anyway,
and in 'normal' modifier stack eval, probably because bare mesh was
awlays requested? But we should not have to be explicit here about it.
Too many things done wrong in original rBd12b3767f81d to list them all
here, hopefully nothing bad sneaked in again this time :|
Also cleaned up a little the 'sort by name', even though (since we only
have two options by default, sort by index and by name) we can abuse it
as a binary option for now, this is not a bitflag...
- When toggling a mode that doesn't support multi editing
only do this once of the active object.
- For sculpt mode create sculpt data since this is needed
for activating other sculpt objects on reload.
We now perform COW -> original data flushing for all the debug values + error
status flags on Drivers/DriverVariables/DriverTargets, as these are only set
when errors are encountered when evaluating drivers.
This switches evaluation of vertices which are on the boundaries
of PTex faces to a single threaded one. While this introduces
some slowdown it fixes ambiguity of PTex index used to evaluate
particular vertex.
Possible alternative solutions would be:
- Do some pre-calculation of index, then do evaluation in threads.
- Try using Gregory patches and see if that makes any affect.
Fix T60235: Flickering of object instances
Implementing a new intelligent mixing mode that combines quaternions
via multiplication requires rewriting the NLA code to recombine array
properties from separate scalar channels during evaluation.
In addition, stable evaluation of NLA stack requires that any channel
that is touched by any of the actions in the stack should always be
set to a definite value by evaluation, even if no strip affects it
at this point of the timeline. The obvious choice for the fallback
is the default value of the property.
To make scanning all actions reasonably efficient, mapping paths to
channels should be done using hash tables.
