===========================
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.
===========================
- Added function to calculate per-track average error.
Made this in libmv c-api, probably should be ported
to libmv pipeline.
- MovieTrackingTrack now holds average reprojection error
which is displayed in Active Track panel and information
text in clip editor (if displaying of names are enabled).
- Make "Clean Tracks" take average error on account.
===========================
- Made naming in libmv-api more uniform.
- Move aspect ration detection of clip to movieclip.c.
- Remove unused width and height from camera intrinsics function.
- Reconstruction should now deal correct with aspect ratio.
===========================
- Fixed occasional crash caused by conflicting access
to non-threadsafe moviecache. Added lock on movie clip
ibuf acquire level.
- A bit nicer feedback from libmv when doing reconstruction.
Now if all tracks and frames were reconstructed average
error would be reported in "notification area".
If there's something failed to be reconstructed warning
message would appear and failed items would be printed to
the console.
===========================
- glog should no flood into logs files now.
- Request from Francois - changes in sliding:
* Anchor point is for sliding the whole marker.
* Square on pattern moves pattern and search relative
to anchor point.
* Square on search moves search only.
- Bundles in 3d viewport are colored by track custom color.
===========================
- Fixed discovered bug with selecting hidden marker areas with mouse.
- Refactor of context structure used for 2D tracking:
* Tracker object is now per-track. This allows to use
different pyramid levels for different tracks and
now search area resizing shouldn't make tracking less
accurate.
* This is also be used for new optimized libmv API.
* This allowed to use OpenMP to track different markers in
separated threads.
This allowed to reach quite cool speedup for multi-core CPU.
===========================
- 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.
