It is now possible to display per-frame track reprojection
error in curve view of clip editor. Simply enable corresponding
option in filter buttons.
Currently displayed using blue color which might confuse with
average reprojection error, further color tweaks are possible
and easy.
Also changed icon track x/y curves. Better icons here are
really appreciated.
whether getting of some property happens or this property is
being changed.
Also made it more clear whether affecting property belongs
to clip or mask datablock.
- Re-arrange functions in headers and implementation file to make them
more grouped by entity they're operating with. Also order of functions
in implementation file should match order of functions in header for
easier navigation.
- Rename some functions to match conventions of naming public functions.
- Some code de-duplication, still some room for improvements tho.
- Split main 2D tracking functions into smaller steps to make it more clear.
Accidentally OpenMP was disabled in some of previous commits, re-enable it.
- spelling - turns out we had tessellation spelt wrong all over.
- use \directive for doxy (not @directive)
- remove BLI_sparsemap.h - was from bmesh merge IIRC but entire file commented and not used.
- Use proper poll functions for tracks curve operators.
- Darken frames outside of scene frame range in curves view.
- Implemented view all operator.
- Implemented jump to current frame operator.
Curve points of tracks curves now can be selected for X and Y channels
separately and can be moved along Y axis of curve viewer, points currently
can't change frame they belong to. This allows to smooth spikes caused by
unwanted marker jump.
Also fixed some mistakes in cancel transform in cases when locked tracks
were being trying to be moved; fixed incorrect calculation of marker speed
for curve drawing.
This commit implements basis stuff needed for object tracking,
use case isn't perfect now, interface also should be cleaned a bit.
- Added list of objects to be tracked. Default there's only one object called
"Camera" which is used for solving camera motion. Other objects can be added
and each of them will have it;s own list of tracks. Only one object can be used
for camera solving at this moment.
- Added new constraint called "Object Tracking" which makes oriented object be
moving in the save way as solved object motion.
- Scene orientation tools can be used for orienting object to bundles.
- All tools which works with list of tracks or reconstruction data now
gets that lists from active editing object.
- All objects and their tracking data are available via python api.
===========================
Commiting camera tracking integration gsoc project into trunk.
This commit includes:
- Bundled version of libmv library (with some changes against official repo,
re-sync with libmv repo a bit later)
- New datatype ID called MovieClip which is optimized to work with movie
clips (both of movie files and image sequences) and doing camera/motion
tracking operations.
- New editor called Clip Editor which is currently used for motion/tracking
stuff only, but which can be easily extended to work with masks too.
This editor supports:
* Loading movie files/image sequences
* Build proxies with different size for loaded movie clip, also supports
building undistorted proxies to increase speed of playback in
undistorted mode.
* Manual lens distortion mode calibration using grid and grease pencil
* Supervised 2D tracking using two different algorithms KLT and SAD.
* Basic algorithm for feature detection
* Camera motion solving. scene orientation
- New constraints to "link" scene objects with solved motions from clip:
* Follow Track (make object follow 2D motion of track with given name
or parent object to reconstructed 3D position of track)
* Camera Solver to make camera moving in the same way as reconstructed camera
This commit NOT includes changes from tomato branch:
- New nodes (they'll be commited as separated patch)
- Automatic image offset guessing for image input node and image editor
(need to do more tests and gather more feedback)
- Code cleanup in libmv-capi. It's not so critical cleanup, just increasing
readability and understanadability of code. Better to make this chaneg when
Keir will finish his current patch.
More details about this project can be found on this page:

Further development of small features would be done in trunk, bigger/experimental
features would first be implemented in tomato branch.
===========================
- Changed 3D viewport reconstruction settings to more usable defaults
- Some code clean-up
- Option to place markers for detected features across the whole frame,
inside grease pencil areas or outside of grease pencil areas.
===========================
DeBalie commit (main changes only):
- Code cleanup
- Selectable tracking graph curves and curve knots
- Graph curve and curve knots can be deleted now
- Fixed wrong write when linking libraries
(error is caused by hardcoded cound of linkable ID blocks)
- Fixed for KLT tracker when using keyframe adjustment
