In some instances, the number of control vertices of a hair could change mid-frame.
Cycles would then be unable to calculate proper motion blur for those hairs. This adds
interpolated CVs to fill in for the missing data. While this will not necessarily result in
a fully accurate reconstruction of the guide hair, it preserves motion blur instead of disabling it.

Scale is multiplicative, and adding it up causes the bone to bloat.

|

We were using int's for bool arguments in BKE,
just to avoid having wrapper functions.

The easy ones - there some much, much trickier to tackle there...
|
|
Notes:
* Really need to address RNA setters case, end up adding way too much
G.main here these days... :/
* Added Main pointer into bAnimContext, helps a lot in anim code ;)

Strip unindented comment blocks - mainly headers to avoid conflicts.

prevent corners errors in raycast.
Using FLT_EPSILON can fail with large coordinate values.
This commit also avoids storing bvhtrees with different settings in BVHCache.

Make this match editmesh picking more closely

- Wasn't clear which functions handle edit-bones.
- Mixed both ebone and edit_bone in names.
- Didn't use ED_armature_* prefix for public API.
See P655 to apply to branches.

Also add lower level mode exit function
|
|
Prepare for multi-object pose mode
|

Split out undo API from ED_util.h into ED_undo.h
|
|
- Use a single undo history for all operations.
- UndoType's are registered and poll the context to check if they
should be used when performing an undo push.
- Mode switching is used to ensure the state is correct before
undo data is restored.
- Some undo types accumulate changes (image & text editing)
others store the state multiple times (with de-duplication).
This is supported by checking UndoStack.mode `ACCUMULATE` / `STORE`.
- Each undo step stores ID datablocks they use with utilities to help
manage restoring correct ID's.
Needed since global undo is now mixed with other modes undo.
- Currently performs each undo step when going up/down history
Previously this wasn't done, making history fail in some cases.
This can be optimized to skip some combinations of undo steps.
grease-pencil is an exception which has not been updated
since it integrates undo into the draw-session.

Tabs in middle of code (mostly for no reason / by accident).

Disconnected bones weren't handled correctly.

Also correctly copy bone tip selection when dissolving.

Premise: When pose bones are selected, applying a pose library should
only affect the selected bones.
This commit fixes a bug where the pose was also applied when there was
no overlap between the selected bones and the bones in the pose. For
example, applying a pose which contains only keyframes for the left
hand, while only right-hand bones are selected, would apply the pose
to the left hand anyway.
The code is now also slightly more efficient; the removed 'selcount'
counter was only used as a binary (i.e. zero or non-zero). It's now
stored as a bitflag instead.

Use common prefix so adding related functions share the prefix.
|
|
Was mixed with edit-mode, centralize mode switching in a single file.
No functional changes.
|

While doing so with Bone_R.001, Bone_R.003, Bone_R.003 etc. is doomed to
issues, doing that on duplicates of actually correctly named bones can
be handy, and safe.
So adding back as an option (was removed in rB702bc5ba26d5).
|
|
Flip names operator changed in rB702bc5ba26d5, to some sensible
behavior. But this breaks common workflow of 'duplicate part of the
bones, scale-mirror new ones, and flip their names'.
So now, instead of doing this in two steps, trying to guesstimate which
bones should get which name, just add option to flip names to duplicate
operator itself. Simpler, safer, and much, much more consitent behavior
and predictable results.

- When returning the number of items in a collection use BLI_*_len()
- Keep _size() for size in bytes.
- Keep _count() for data structures that don't store length
(hint this isn't a simple getter).
See P611 to apply instead of manually resolving conflicts.

Technically this was not a bug, as this functionality was not meant to
work. (Drivers were already handled though, as they are part of the rig)
It was assumed that there was little value in having this functionality
available, as in most pipelines, animation production only begins after
the rig has been locked down (see bug report comments for more details).
On reflection, in most common situations, there's probably no harm in
doing these rna path fixups. This commit takes advantage of some similar
code I recently put in place in the Grease Pencil branch (for joining GP
objects and their layers).
Important Note for Animators/Riggers/TD's:
Please be aware that after joining armatures, some of the animation may
still need to be redone (due to changes in the transform hierarchies/
transform spaces that the animation is applied in). We do not attempt
to correct for these problems, and it is unlikely that we will in future.

The "Apply Pose as Rest Pose" operator now affects Bendy Bone settings
too, making it possible to use interactive posing tools (e.g. Pose Sculpting
brushes) to get the desired shape for the rest-pose shape of Bendy Bones.
When such posing tools are available, this change makes it easier to get
the desired Bendy Bone shapes, as you are no longer restricted to using
buttons to get the desired effects.

Conventions were already followed nearly everywhere.

bone needing to have any paths itself)
This commit introduces the following changes:
* Modified the poll callback on the "Update Paths" operator for bones
so that it only checks if there are bones that have motion paths
(instead of checking whether the active bone has paths).
This makes it easier to update paths without having to first select one
that has them - useful when the paths are all on hidden/hard-to-select bones.
* Add a readonly property, "has_motion_paths" to the animviz.motion_path
RNA struct, providing easier access to the internal flag used above.
This makes it possible for the UI to display the "Update" button without
having to check various bones for motion paths.
Notes:
* The flag being used in these changes already existed, and was only really
intended for internal use. However, since it was already used in many places
for determining if auto-update of all bone paths was needed (e.g. after certain
editing ops), it should be safe to use here too.
* The update_paths operator currently bakes all paths when activated, so there's
currently no loss of functionality with changing to not checking if the active
bone has any paths (e.g. we couldn't only update the active bone only either).
That is still listed as a todo in the code.

This makes code closer to id_override/assent-engine ones, which
introduce a new type of linked data, and hence reserve
ID_IS_LINKED_DATABLOCK to real linked datablocks.

This fix enables the usage of bbones easing parameters for edit and pose mode seperately. This allows animators to take advantage of the functionality and may eliminate confusion as the parameters now behave similar to other bbone parameters.
Note that splitting the parameters between the modes effectively creates a new parameter set. Blend files of previous versions do not contain this information and will have the values set to 0 on load. As it broke backwards compatibility for pose mode values anyway, I also took the liberty to rename the easing parameters in some places for consistency (which breaks edit mode values).
