===========================
- Fixed some silly things ni DNA design. Now all
reconstruction data is stored in Tracking->Reconstruction.
Please, re-solve your cameras -- reconstruction data
wouldn't be read from files saved in blender below this
commit.
- RNA accessors for reconstruction data.
- Store average reconstruction error in new reconstruction
structure and show it in clip editor header after
reconstruction.
- Highlight failed to reconstruct frames with red in cache line.
- Added "group" "Failed Tracks" in Select Grouped operator,
Meant to be used for selecting tracks bundles from which
failed to to be solved.
- Hotkey to delete marker: Shift-X.
- Jump to next/prev failed frame operator. Hotkeys are
Ctrl-Shift-Left/Right Arrow.
===========================
- Do not show frame boundary border when stabilization isn't enabled.
- Separate stabilization settings from display in clip editor.
Now clip can contain stabilization data but still be displayed
un-stabilized in clip editor.
- Internal changes in stabilization:
* Use separated location/scale parameters rather than 4x4 matrix.
In some ares "decomposed" data is needed (text draw functions, i.e.).
Also such decomposed data could be used in compositor.
* MovieClip now uses own structure for cache where additional data
can be stored. MovieCache structure now one of properties in
this new structure.
* Get rid of stable image buffer stored in MovieClipStabilization
structure. Pre-created buffer for scaling still stored there.
This helps to keep playback realtime -- re-creating this buffer
introduces ~15% slowdown.
- Added sliders to 2D stabilization panel which controls intensity
of translation/scale which applies on shot.
- Added filter type to Stabilize2D compositor node. Supports nearest,
bilinear and bicubic interpolation.
- After discussion with Sebastian and Francois added new node called
Transformation. It can apply translation, rotation and scale. It's
not the same thing as applying this components separately -- all
transformation is happening inside "canvas". And it should be more
accurate on interpolation and sub-pixel translation.
Need to check order of applying translation/scale/rotation btw.
- Added output sockets to movie clip compositor node. They holds
stabilization data which can be used by Translate or Transform
nodes.
- Minor fix of UI issues in Display panel.
===========================
Implemented 2D stabilization:
- Based on average point of several tracks.
- Tracks for stabilization are controllable from
"2D stabilization" panel.
- Implemented autoscaling. Could fail if average point is
too close to frame boundary.
- Background clip in 3D viewport and MovieClip input
compositor nodes are using stable shot.
Some internal weak things:
- Stable shots aren't cached in moviecache. There is
only one "slot" for stable shot inside stabilization
structure.
- This could fail if several threads are requested different
frames (for example when starting playback, pause to make
Nodes Editor trigger refresh, continue playback).
- Due to it shouldn't crash i decided to implement better
caching for stable shots a bit later.
Enabled by default and also enabled for older filesm so
there should be no regressions.
In some cases it's useful to not use subdivided uvs for multires.
===========================
- Split clip hotkeys into two categories:
* Global
* Editing
This allows to re-use such hotkeys as track markers
from properties region without worrying about conflicts.
- Anchor point could now be offseted from marker position.
- Pattern can now be symmetrical relative to marker position only.
- Changes to mouse sliding:
* Left top rectangle used for marker position and now
it's half inside and half outside of marker.
* Right bottom corners are for size.
* Anchor point can be slided with mouse to adjust offset.
- Resolved conflict caused by left-mouse selection option.
Now it works perfectly with sliding -- no more "sticky" keys or so.
- Fixed some typos.
On dragging a non-connected node on a noodle, it will insert it.
Functionality tweaks are possible, but it already feels non-intrusive.
Rules:
- Insertion only when a single noodle is intersecting with node.
- Default connects first matching socket type.
- If no socket match, it connects the first.
===========================
- Fixed crash when transforming disabled marker.
- Select Inverse wouldn't select hidden parts of markers.
- Movie Clip display aspect ratio is now available on Display panel.
Generated images would not be re-generated with a float buffer on load, even when selected on creation.
Now save the float buffer setting as a generated image flag.
This means you can enable before baking to enable baking to a float buffer.
===========================
- Fixed crash when holding down S and R keys.
- Fixed deleting of first marker.
- Tracking should now work fine with float buffers.
- Added option to show distortion grid. It's most probably
temporary solution until [auto]calibration tools aren't
merged.
This grid defines straight lines on the image.
===========================
Test feature: configurable marker colors in Clip Editor.
Use presets, so plenty of different color could be defined and
easily re-used.
===========================
- Hide all reconreuction-related sliders from Display N-panel
of 3D viewport if "Show Reconstruction" is turned off.
- Added setting for shape of bundle. Default is sphere.
===========================
- Internal change: do not use maroses for checking the only
one bit of track/marker flags.
- Do not display track name for disabled markers when
"Show Disabled" is turned off.
- Option to lock tracks. Locked tracks can't be be moved,
scaled, re-tracked and so.
===========================
- Selected bundles are now highlighted with outline.
It looks more Blender-way of highlighting selected items.
- Added option to show bundles names in 3D viewport.
- Bundles now coudl be selected from 3D viewport.
===========================
- Fixed smal lbug with mouse selection.
- Added option to show tracks names and their states
(disabled, keyframed, estimated, tracked).
===========================
- Remove set but not used variable in clip buttons.
- Set keyframe when sliding marker with mouse.
- Also set keyframe when sliding from preview widget.
xsch and ysch were originally planed to replace the scene->r.xsch/r.ysch
however in blender/3dview we still need to use the r. values. Therefore we can't really run
from using those values even in bplayer. So removed the values in gamedata.
The way it's now, render values (xsch and ysch) are responsible for aspect ratio and gamedata xplay and yplay are responsible for the size of the window.
* New object pointers can't be loaded properly for library linked groups, so the weight groups now store an index to the group objects at save time. This index is used at load time to set the objects without relying on the old pointers.
* If the library linked group is modified the indices can be wrong, but this can't really be avoided easily as there's no way to relate objects in a linked group between loads.
===========================
Changes to tracking camers settings, so they could
be copied to Blender camera on reconstruction.
Sensor height doesn't make any sense yet for tracking camera.
===========================
Commiting patch #24427: Editable camera sensor size (meaningful focal length units)
Thanks to:
Matt Ebb (author of original patch)
Ejner Fergo (porting patch through versions)
Brecht Van Lommel, Dalai Felinto, Campbell Barton (patch review)
Cant't commit changes to addons (they aren't branched, so some of them
could be broken now)
===========================
Initial implementation of Scale operator.
There's no access from operator panel to operators defined for
Clip Editor space, so distance can't be controlled as operator
property.
Added new property to MovieTrackingSettings for this.
===========================
Small fixes and features:
- Fixed broken toolshelf for empty space clip.
- Added option to hide disabled tracks.
- Do not send disabled markers to tracking job.
- Fixed bug with disabling marker when tracking backwards.
- Fixed bug with unset principal point by default.
- Hide bundle projection for disabled markers.
- Flip orientation when hitting "Set Axis" when bundle is
already defines axis.
===========================
Previous solution to make bundles work for parented camera
wasn't very nice. It could totally confuse depsgraph and it's
quite slow.
Now i've implemented function where_is_object_mat which makes
almost the same as where_is_object_time, but it:
- Does not applies constraints.
- Assumes matrices for all dependencies are valie already
(handles by depsgraph).
- Doesn't make any changes to object itself or it's
dependencies.
===========================
Attempt to fix bundles position for case scene camera has got
other constraints than CameraSolver (mostly to support camera
parenting to other object for scene orientation).
Use a bit silly logic to calculate camera matrix to orient
bundles in 3d space: temporary disable all CameraSolver
constraints for camera, re-calculate object matrix, use it
to orient bundles and clear temporary flag.
This allows to parent both of camera and mesh created from
bundles to the same Empty object and both of bundles and
mesh vertices would have the same coords in camera space.
Also removed copying of location/rotation from camera to
bundles object in "Bundles to Mesh" operator.
===========================
- Fixed buf with under reference for Follow Track constraint.
- Get rid of BKE_movieclip_approx_size. Rather than accessing
to cache with previously set frame number it'll be easier to
store size of last accessed in "runtime" DNA.
===========================
- Reduced size of widget for camera focal length units.
Also changed labels to mm/px. Now it's much easier to read
values and titles here.
- Reordered settings in "Display" panel. Hopefully it's
now easier to read options here even when N-panel
isn't large enough.
- Fixed bug with "disappearing" labels from "Active marker" panel.
- If search areas are hidden and marker is disabled,
make pattern area red rather than displaying nothing for
this marker.
- Internal change: "show marker path" became "show track path".
- Lock shape of pattern to square by default. Control unlocks
this shape.
- Hitting escape when sliding cancels changes and stops sliding.
- Search areas are hidden by default now. No big benefit of
looking at them now after changing default settings to
2D tracker and pattern/search size.
- Both of Toolshelf and Properties panels are now visible
by default.
- Move keyframes from Properties panel to Toolshelf.
It is a key thing which makes reconstruction correct and
this options were too hidden and not so convenient to
use.
===========================
- Fixed incorrect usage of RNA structure for
CameraSolverConstraint.
- Fixed some typos in object_constraint which were
casting CameraSolver data to FollowTrack data.
- Tracking-related constraints now have got option
"Use Defult Clip" which makes them use clip set as
active for scene. Enabled by default.
- Set active blender camera focal length after reconstruction.
- Corrected offset of sequence images. Now first image from sequence
should be at scene frame 1.
===========================
- Changed libmv api to use doubles instead of floats.
No real benefit rather than keeping API uniform.
- Optimized reconstructed camera search. It's optimized for
playback, not random access.
- Added option to show projection of bundles into footage.
To see bundles "Show Bundles" from Display panel should
be enabled. Used very rough limit of 3 px to consider projection
is fine. Colors are still hard-coded. Not sure it could be useful
to make them configurable.
- Added option to mute footage. It could be useful to check
if markers/bundles are moving smoothly.
- Added selector for focal length units.
===========================
- Implemented hide/show track functionality.
- Small re-exposing Marker menu into UI.
Now it's called "Track". Added new operators there.
- Set reconstructed clip as active to scene.
