===========================
Initial implementation of graph view for movie tracking data.
Used the same UI-side approach as preview region for sequencer:
create region for graph-related information inside clip editor.
It's easier and nicer than trying to hack graph editor which is
currently designed to work with AnimData only. Trying to make it
more abstract to deal with any kind of data doesn't seem be real
benefit for now.
Currently supported displaying per-frame average error and
selected tracks' movement speed (pixels per frame).
Additional changes:
- Collect per-frame average error after solving.
- Split space clip drawing code into different files.
- Added per-frame average solving error.
===========================
Some improvements for feature detectors:
- Sort features by score when filtering features by
distance using FAST library.
- Added option to place markers only in areas outlined
by grease pencil.
===========================
Added option to choose which method to use for feature detector: FAST or Moravec
Moravec was supposed to be more "stable", but it collected worse feedback.
before returning back to FAST detector added option to easier toggle between
different detector to compare it's result and find out if we can leave only FAST.
===========================
Support for (un)distortion of images with overscan. Needed for
easier keeping this up-to-date until proper overscan support is
implemented in renderer. Not exposed into UI yet at all.
===========================
Fixed threading issues used to happen when compositor tree
and rendering happened in the same time. Problem was caused
by cached camera intrinsics stored in MovieTracking structure
and access to which wasn't thread-safe.
Now each movie distoriton mode stores it's own camera intrinsics
in it's storage which makes compositor (un)distoriton be totally
thread-safe and this also makes compositor tree faster when
(un)distortion happens on images with different resolution.
- Upgrade Recast library to latest portable version
- Implement recast_qsort based on FreeBSD qsort.c to have
portable thread safe quick sort for use in conversion routine.
- Better default value for the Build Navigation Mesh operator
===========================
- Merge Movie Distort and Movie Undistort nodes into one node
called Movie Distortion where action (distort/undistort is specified).
- Implemented more proper distortion/undistortion for scaled images.
NOTE: Please, delete distortion nodes with current blender first
before opening files with blender versions from this commit/
===========================
Lookup grids used for image distortion/undistortion are now
caching and re-building if distortion settings are changing.
This speedups compositor node for cases distortion model isn't
changing, but first run and runs after changing distortion
coefficients is still slow.
===========================
- If render size is set to "Full Render" and undistorted render
is enabled, do on-fly undistortion so distortion coefficients
can be visually verifed before baking.
- Made slight change in libmv-side to survive with large distortion
coefficients. Hope this change is fine.
- Some declarations after statement left.
- Do not use static inline functions in MOD_navmesh. It produces errors
with msvc and not sure it's actually helps -- optimizer should
make it inlined itself.
===========================
- Do not disable track when tracking frame-by-frame and tracking
threshold became bad.
- Show anchored image in track preview widget.
- Do not show search area for non-selected and disabled markers.
- Keep anchor constant position when sliding offset parameters in panel.
- Re-enabled occasionally disabled openmp for tracking.
- Renamed clearing operator so now buttons are more clear.
- Updated eigen to the very recent version.
NOTE: I had to enable static aligning again due to it gave crashes
when tracking on my new laptop. I'm not sure it'll work fine
on another systems.
and it's callback.
Also do not use char constants like 'NAVM' which is casting to int.
And added defautl section to switch in KX_NavMeshObject::DrawNavMesh.
- rearrange structs to work for 64bit
- define all vars before goto's
- ifdefs for qsort_r/qsort_s
- dont cast pointers to int only for NULL checks
- dont printf STR_String directly, get the char pointer from it
also minor change to gpu py module, no need to pass empty tuple to PyObject_CallObject, can just be NULL
Change OURPLATFORM from "linux<major_version>" to simple "linux".
Since new policy for linux kernel versions that major version in
platform doesn't make much sense for building rules so the same
rules could be used for both of linux2 and linux3 now/
Tested on both of linux2 and linux3 systems.
===========================
Bundle new libmv to fix crash caused by some errors in detector.
This commit makes SAD tracking much slower because now it supports
afgine tracking. Not implemented in Blender yet to keep commits
more clear.
===========================
Stop SAD tracker when error becomes too high.
Maximal allowed error value is controlled in Tracking Settings panel.
I haven't been able to find value which will work for most of cases
so it's now quite stupid value of 0. Currently values of 2-6 gives
quite nice result, but it depends on footage.
Upcoming changes from libmv side related on returning normalized SAD
would help here. Until this, please set max_sad manually.
===========================
- Bundling new libmv, issues with undefined uint and C99 functions should gone.
- Changes to Detect operator to match new API.
===========================
- Bundle new version of libmv.
- Use image from nearest track's keyframe as reference for tracking.
This should reduce drifting.
- Added option to switch to new SAD tracker.
This tracker doesn't support pattern with variable size (yet?)
and always uses pattern 16x16px.
Tracker could be choosed in Tracking Settings panel.
===========================
- Distortion/undistortion were accidentally swapped in both of grease
pencil calibration and grid.
This was fixed but distortion coefficients should be re-adjusted.
There are some issues with high distortion coefficients but it
came from libmv and until it'll be fixed there nothing really
can be done here.
- Fixed displayed aspect ratio for muted footage when pixel/display
aspect ratio is differ from 1.0 or proxy size is not Full Render,
- Added c-api for image distortion/undistortion, Not used yet.
===========================
Bundling new version of libmv. It's repo is ready for
bundling again, some patches which were applied on our
side are in libmv repo now.
This new version of libmv also contains patch from John Carpenter
which makes reconstruciton a bit more "stable" -- some kind
of fallback algorithm.
