selected keys
that end up on the same frame
Currently, when scaling keyframes in the Dopesheet, if multiple
selected keyframes end up on the same frame post-scaling, they
would not get removed by the "Automerge" setting that normally
removes duplicates on the same frame.
This commit changes the behaviour so that when multiple selected
keyframes end up on the same frame, instead of keeping all these
around on the same frame (e.g. resulting in a column of keyframes
on different values), we will instead merge them into a single
keyframe (by averaging the values). This should result in a
smoother F-Curve with fewer "stair-steps" that need to be carefully
cleaned out afterwards.

This shouldn't affect anything currently, as this function doesn't appear
to get used anywhere.

name-based-filtering is enabled
This bug took a while to track down. In the test file with this report,
the Nla-Strip Control Curve for strip time would get disabled if you
changed the NLA Editor to a second Graph Editor instance.
It turns out that because this second Graph Editor would have the
"filter fcurves by name" option enabled, this would trigger a lookup
of the referenced property's name (in order to test whether it matched
the filtering criteria). However, since that filtering code was written
before the introduction of these curves, it still assumed that the names
for these Control Curves should be handled the same as for standard FCurves.
Unfortunately, that doesn't work, as the property lookups fail if the standard
method is used - when the lookups fail, the F-Curves get tagged as being
invalid/disabled (and need to be reset using the "Revive Disabled FCurves"
operator).
Note: The changes in this patch look complicated, as I've had to shuffle
a bit of code around so that the name-filtering check can have access to
the additional info it needs. In the process, I've also removed the earlier
(hacky) approach where the control curves were getting added to a temp
buffer to get changed from normal FCurves to special ANIMTYPE_NLACURVES.

Applying the same fixes as introduced in 98d797b67c07e85889768bf8ecde292e9e6f70e9
this time, for the Graph and NLA editors

Not sure why we need a relation from solver to a tip local transform, this
will be handled via parent relation.
Fixes remaining dependency cycles reported in T54083.
|
|
It is not possible to address transform at particular position of constraint
stack, and when constraint is being addressed is usually from driver variable.
This fixes some of dependency cycles reported in T54083.

|
Now it's possible to have debug messages for following things:
- Graph construction
- Graph evaluation
- Graph tagging
|
|
Was accessing past the array boundaries.
Should be safe for 2.79a.
|
|
Handy to quickly see if a fix fixed any of the cycles in a real rig,
or whether it's introduced new ones.
|
|
This would use uninitialized filename variable,
looked into supporting this however generating proxies currently only
works for movies.
|
|
Using same name for two different things is not the best idea ever...
|
|
This is a regression in rB4f1c0a1 which only allowed cutting haior at the
second segment only, while there is nothing wrong with cutting hair at the
first segmewnt.

Don't use dm->get*Array for DM you don't own. This call can allocate temporary
CD layer, which is not thread safe at all.
Also removed hard-coded logic around CDDM check. new functions will do same
logic, but are mode DM-type-=independent.
|
|
We shouldn't mix image pool acuisition with and without user provided,
the fact that internally image.c uses last frame from Image datablock
confuses the logic.
|
|
This wasn't used, tessface is being phased out.
Caller can run explicitly if needed.
|
|
Optionally don't remap indices for objects.
Checking all objects parent's would reference a freed pointer
while freeing all objects.
In the case of dynamic topology there is no use in keeping track
of hook/vertex-parent indices.
Also disable this when creating meshes for undo storage
since adding an undo step shouldn't be modifying other objects.

Sync API changes from 2.8 to master.
|
|
|
|
|
|
|
|
Some of these API's can have 3D versions, explicitly name them 2D.
|
|
regarded by the animation importer, so it was creating very odd results
|
|
(gives nicer output for inspection)

(save and reload).
Once 'losing lib' issue is fixed (in previous commit), we have new issue
that this could lead to several copies of the same linked data-block in
.blend file. Which is not good. At all.
So had to add a GHash-based check in libraries reading code to ensure we
only load a same ID from a same lib once.
|
|
(save and reload).
The issue was that when a same lib was found several times in loaded
.blend, we'd only keep the first occurence. But since Blender expects
next data-blocks to belong to last found library, we could actually
be adding data-blocks assigned to copies of the duplicated lib to
another, totally unrelated lib.
Those data-blocks were then obviously not found when actually loading
libs content, and lost.
Note that this only fix one part of the issue, current code can
generate several copies of same linked data-block now, will fix in
another commit.

In general 2.8 files may not be readable in master, but might as well fix
this case so all the lib/tests can be opened still.

While the script should be using INVOKE_PREVIEW for operators in clip view,
window manager was lacking some switch statements.
Thanks Brecht fore review!

- Use BLI_threadpool_ prefix for (deprecated)
thread/listbase API.
- Use BLI_thread as prefix for other functions.
See P614 to apply instead of manually resolving conflicts.
|
|
- 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.

See https://wiki.blender.org/index.php/Dev:Doc/Code_Style#Braces_with_Macros
|
|
This is kind of doesn't matter where macro itself is defined.
We should stick to the following:
- If some macro is actually more an inline function, follow regular
function name conventions.
- If macro is a macro, type it in capitals. Use module prefix if that
helps readability or it if helps avoiding accidents.

This completes twist feature, which is now possible to also control by
texture. Since textures can not easily contain negative values as well,
same trick with 0.5 neutral as vertex groups is used.
All in all, this twist features allows to do following things.
Original hair:
{F2287535}
Hair with scientifically calculated twist value of 0.5:
{F2287540}
And we can also twist braids in opposite directions dependent on left/right
side:
{F2287548}
|

vgroups and textures
cpa->num points to a face index on BASE mesh, but get_child_modifier_parameters()
expects index on a FINAL dm. So wrong index was used here.
|
|
The idea is to give a control over direction of twist, and maybe amount of
twist as well. More concrete example: make braids on left and right side of
character head to be twisting opposite directions.
Now, tricky part: we need some negative values to flip direction, but weights
can not be negative. So we use same trick as displacement map and tangent normal
maps, where 0.5 is neutral, values below 0.5 are considered negative and values
above 0.5 are considered positive.
|

It allows to have children hair to be twisted around parent curve, which is
quite an essential feature when creating hair braids.
There are currently two controls:
- Number of turns around parent children.
- Influence curve, which allows to modify "twistness" along the strand.

result in the point
This isn't supported since there are subsequent reads to all point coordinates
after modification started.
Probably we need to create a temp copy of point, but that's like extra CPU
ticks.
|
|
Use single structure. It seems we will need to pass more information soon,
so better to do it via the structure.
|
|
|
|
|
|
It seems to be useful still in cases where the particle are distributed in
a particular order or pattern, to colorize them along with that. This isn't
really well defined, but might as well avoid breaking backwards compatibility
for now.
|
|
These are used for randomization, so it's convenient if the index is already
hashed and consistent with the Object Info node.
|
|
This makes it really hard to spot errors when function signature changes.
|
|
|
|
Avoids redundant calls to the curve evaluation.
|
|
|
|
Allow exiting editmode from non-active scene.

This is like the only way to add variety to hair which is created
using simple children. Used here for the hair.
Maybe not ideal, but the time will show.
