Function `SEQ_transform_handle_overlap` was declared in sequencer module
header file, but it was defined in editor/transform module.
Move definition to sequencer module.
|
|
Function `SEQ_transform_seqbase_shuffle_time` did not have access to
strip effects, and therefore could not handle their animation. Since
now transformation knows what strips can't be directly moved, but their
position depends on other strips, this collection of strips is passed as
argument, so animation can be offset correctly.

Apply scale factor when preview aspect ratio is not 1:1.

It's an old behavior. Not really considered a bug.
But snapping to faces is already supported in this case.
And allowing snapping to other elements is not disruptive.

Curves can have a Mesh evaluated, but only objects of type Mesh have
EditMesh.
This bug is harmless because `sctx->editmesh_caches.remove(value)` only
works with pointers and `BKE_editmesh_from_object(ob_eval)`, even though
it doesn't actually return a `BMEditMesh`, it still returns a pointer
that doesn't exist as a key.

NOTE: this patch originated in T98015 which was split into multiple
reports. While it could be split into multiple patches these are very
much related so keeping as one for now
This patch fixes the following issues:
[1] autokeying transforms in preview only creates keyframes if there is
an FCurve already
[2] autokeying transforms in preview only creates keyframes for
rotation/scale if rotating/scaling around cursor (should keyframe
position as well)
[3] autokeying transforms in preview does not work during animation
playback
For [1], a param was added to `ED_autokeyframe_property` which can tweak
its default behavior of only creating keyframes on already keyed
properties (which was fine because this is mostly called from buttons
where this behavior is desired). Callers such as gizmos (or the VSE in
our case) can use this additional param so that keyframes are also
created on "not-yet-keyframed" properties.
For [2], the pivot is checked and position properties also keyed if
necessary (which is also consistent with the way objects are keyed in
the 3DView)
For [3], `animrecord_check_state` was changed to be able to work on
scenes as well and the transform system in the VSE preview was made
aware of the screen's `animtimer`.
NOTE: there are still things to be improved for keyframing in the VSE,
the most obvious is probably a `keyframe_insert` operator (with
keyingsets)

Since [0], transform gizmos are no longer hidden during transform.
The same can be observed for rotation gizmos.
However, as a workaround for these rotation gizmos, there was already a
drawing utility running.
With the gizmo and the utility this drawing is now being done twice.
So remove the utility/workaround and update the gizmo accordingly.

into enums
The transformation snapping code contains a bunch of `#define`s, some ambiguously or incorrectly named attributes. This patch contains refactored code to improve this. This patch does (should) not change functionality of snapping.
Clarified ambiguously / incorrectly named attributes.
- "Target" is used to refer to the part of the source that is to be snapped (Active, Median, Center, Closest), but several other areas of Blender use the term "target" to refer to the thing being snapped to and "source" to refer to the thing getting snapped. Moreover, the implications of the previous terms do not match the descriptions. For example: `SCE_SNAP_TARGET_CENTER` does not snap the grabbed geometry to the center of the target, but instead "Snap transforamtion center onto target".
- "Select" refers to the condition for an object to be a possible target for snapping.
- `SCE_SNAP_MODE_FACE` is renamed to `SCE_SNAP_MODE_FACE_RAYCAST` to better describe its affect and to make way for other face snapping methods (ex: nearest).
Refactored related `#define` into `enum`s. In particular, constants relating to...
- `ToolSettings.snap_flag` are now in `enum eSnapFlag`
- `ToolSettings.snap_mode` are now in `enum eSnapMode`
- `ToolSettings.snap_source` (was `snap_target`) are now in `enum eSnapSourceSelect`
- `ToolSettings.snap_flag` (`SCE_SNAP_NO_SELF`) and `TransSnap.target_select` are now in `enum eSnapTargetSelect`
As the terms became more consistent and the constants were packed together into meaningful enumerations, some of the attribute names seemed ambiguous. For example, it is unclear whether `SnapObjectParams.snap_select` referred to the target or the source. This patch also adds a small amount of clarity.
This patch also swaps out generic types (ex: `char`, `short`, `ushort`) and unclear hard coded numbers (ex: `0`) used with snap-related enumerations with the actual `enum`s and values.
Note: I did leave myself some comments to follow-up with further refactoring. Specifically, using "target" and "source" consistently will mean the Python API will need to change (ex: `ToolSettings.snap_target` is not `ToolSettings.snap_source`). If the API is going to change, it would be good to make sure that the used terms are descriptive enough. For example, `bpy.ops.transform.translate` uses a `snap` argument to determine if snapping should be enabled while transforming. Perhaps `use_snap` might be an improvement that's more consistent with other conventions.
This patch is (mostly) a subset of D14591, as suggested by @mano-wii.
Task T69342 proposes to separate the `Absolute Grid Snap` option out from `Increment` snapping method into its own method. Also, there might be reason to create additional snapping methods or options. (Indeed, D14591 heads in this direction). This patch can work along with these suggestions, as this patch is trying to clarify the snapping code and to prompt more work in this area.

Scaling handles while dragging could be distracting, especially at
extreme values where handles could become large on-screen.
Now all gizmos are shown while scaling.
GIZMO_GT_arrow_3d now now support changing their length while being
dragged as well as negative lengths.
|
|
This resolves a minor inconsistency displaying the scale gizmo handles
since they're cubes it's noticeable when they're not axes aligned.
|
|
When interacting with translate/rotate/scale gizmo, show the gizmo while
it's in use. There are some exceptions to this, as showing all scale
gizmos while scaling causes the gizmos to become large & distracting so
in this case only the gizmo being dragged is shown.
Resolves T63743.

Now gizmos forward the original event to transform so assuming an LMB
event is no longer needed.

This patch makes it possible to manipulate strips without need to use
update functions to recalculate effect and meta strips.
Prior to this change function `SEQ_time_update_sequence` had to be used
to update mainly effects and meta strips. This was implemented in a way
that relied on sorted list of strips, which can't always be done and in
rare cases this approach failed.
In case of meta strips, `seqbase` had to be passed and compared with
"active" one to determine whether meta strip should be updated or not.
This is especially weak system that is prone to bugs when functions are
used by python API functions.
Finally, other strip types had startdisp` and `enddisp` fields updated
by this function and a lot of code relied on these fields even if strip
start, length and offsets are available. This is completely
unnecessary.
Implemented changes:
All effects and meta strips are updated when strip handles are moved or
strip is translated, without need to call any update function.
Function `SEQ_time_update_sequence` has been split to
`SEQ_time_update_meta_strip_range` and
`seq_time_update_effects_strip_range`. These functions should be only
used within sequencer module code. Meta update is used for versioning,
which is only reason for it not being declared internally.
Sequence fields `startdisp` and `enddisp` are now only used for
effects to store strip start and end points. These fields should be
used only internally within sequencer module code.
Use function `SEQ_time_*_handle_frame_get` to get strip start and end
points.
To update effects and meta strips with reasonable performance, cache
for "parent" meta strip and attached effects is added to
`SequenceLookup` cache, so it shares invalidation mechanisms.
All caches are populated during single iteration.
There should be no functional changes.

The logic of skipping selected handles was inverted
and confusing.

This limiting prevented visual keyframing from working correctly and is
not consistent with object rotation, so limiting is removed.

The change was kind of intentional on {rB21e72496a629}.
That commit made mouse movement to "select" the contraint in Auto
Constraint a requirement.
This deduplicated the code a bit, but this requirement is not
comfortable for the first "selection" of the contraint.
So the constraint "selection" is now done in two ways:
- If there is no contraint, the "selection" is done immediately;
- If there is already a constraint, the "selection" is delayed by 1 event to simulate a constraint cancellation if there is no mouse movement.

The shortcut is G-G.
Caused by loop argument "shadowing".

Switch from a single function with a lot of branching at its top level
to dedicated function calls with own documentation.
|
|
Pattern is expected to be freely resized to any size, and the search
area s to become bigger when needed.
Remove confusing pattern size clamping which was actually clamping
search area.
There should be no functional changes.

In rare cases the mesh has not been evaluated when snapping, this fix
just prevents the crash as is done elsewhere in Blender when the
evaluated mesh isn't available, there is a separate report (T96536)
about evaluation not working properly.

Unlike 3Dview snapping, UV snapping is always done to the UV closest to
the mouse cursor, no matter the distance.
From the user's point of view, this appears to be an inconsistency (See
{T93538}).
Therefore, set a minimum distance for snapping and, as in 3D View and
highlight the snap with a drawing of a circle.

This was reported explicitly for originally being in face selectmode,
but could also crash when in vertex selectmode (when doing multiple
cuts).
The reason here is that `MESH_OT_loopcut` switches to edge select mode
(needed for `TRANSFORM_OT_edge_slide`, done in `ringsel_finish`), but was
only doing this on the active object's editmesh, all other participating
meshes would keep their selectmode which would now be out of sync with
both the active object's editmesh and scene settings for these.
This causes problems later in 'Select Linked'. Here, a mixture of
objects are used. First the viewcontext is set up with the active
object, then all participating objects are iterated (changing the
viewcontext to another object), then `unified_findnearest` would use that
changed viewcontext which would now contain the last object iterated. To
repeat: this could now have a different selectmode than the active
object which is later **again** used to get the nearest `BMElem` from in
`EDBM_elem_from_selectmode`. So in the failing case, we could get an
edge (but no face because of edge selectmode) from `unified_findnearest`,
`EDBM_elem_from_selectmode` would return NULL though (edge provided, but
in face selectmode), leading to the crash.
To solve this I assume it is best to change selectmode on all
participating meshes in multi-object editmode loopcut if necessary so
these are always in sync for following operations.
Alternatively, `Select Linked` (and probably lots more operators) would
have to be tweaked to pay closer attention which object is really used
to get selectmode from.
Note the selectmode is actually set back from edge selectmode in certain
cases (see `USE_LOOPSLIDE_HACK`), this patch changes that as well to act
on all participating meshes.

When height is limited, it is defined by space occupied by strips,
but at least channels 1 to 7 will be always visible. This allows it to
easily overview timeline content by zooming out to maximum extent in Y
axis and panning in X axis.
More channels can be "created" on demand by moving strip to higher
channel. When strip is removed and highest channel becomes empty, view
will stay as is until it is moved down. Then new highest point is
remembered and it is not possible to pan upwards until strip is moved to
higher channel.
Limiting takes into account height of scrubbing and markers area as
well as scrollers. This means that when zoomed out to maximum extent,
no strips are obstructed by fixed UI element.

This patch adds the drag and drop strip previews in the VSE.
It also adds two new functions to the drag and drop API.
1. "draw_in_view" for callbacks that wants to draw elements in local viewport coordinates
2. "on_drag_start" that can be used for prefetching data only once at the start of the drag.

The editing data of a `SURF`s is similar to that of Curves and should be supported for snapping.
But unlike Curve objects, for snapping, only support the nurb points if the object is in edit mode.
This matches the solution for Meshes and avoids having to create a kind
of "boundbox" for the SURF nurb points.

The problem is old.
rB52be06301257 (fixed by rB4b35d6950d4f) just masked it.

In some cases, selected elements do not contribute to snapping.
