===========================
Fix for camera solver on windows.
There were two problems:
- Static align in Eigen should be also disabled for libmv.
- SSBA doesn't work correct for windows when optimization is
turned on.
There's no other way rather than disable optimization for
the whole extern/libmv. This leads to 3-4x slowdown, but it's
really the only thing we could do now.
Keir is going to drop SSBA out and replace it with Bundler,
so it shouldn't be a major problem.
===========================
- 32 bit linux compilation should be fixed now.
- Camrea reconstruction data should be better now
when there's no reconstructed cameras.
- Implemented "Set Origin" operator
- Added "Specials" W-key menu for SpaceClip.
Supports such operators:
* Enable track
* Disable track
* Set origin
===========================
- ColaMD moved from OpenNL to extern/.
It'll be needed for libmv. Also, it's a bit updated from
year 1999 to 2007.
Need to be tested for regressions.
- Updated bundling script for libmv. Now it uses fuller
subset of this library.
- Bundled new libmv.
- Request from Keir: add command line argument to toggle logging
stuff on. Currently, if Blender is launched with -d argument
libmv would start printing logging messages. There's no
argument to increase verbosity, but there's API in libmv-capi,
so it'll be easy to add.
- Finally fixed crash when ibuf is acquiring with user=NULL.
- Added ActiveClip property to the scene. This clip is used
as default value for new match-moving constraints.
- Added some flags to Display panel of View3D. Related on
displaying match-moving stuff.
- Internal change: bundles data moved inside to MovieTrackingTrack.
- Initial implementation of 3d reconstruction.
- Added constraint "Camera Solver". This constraint is supposed
to be used to make camera follow the reconstructed camera path.
- Added "reference" property to "Follow Track" constraint.
Now object could be "parented" to 2D track position or to
3D bundle position.
The very quick guide:
To use reconstruction you should have footage with tracked markers,
choose two keyframes in "Tracking settings" panel. There should be
quite noticeable parallax effect between this two frames. This
is used to initialize reconstruction stuff.
Camera data (focal length and optical center) should be filled in
"Camera Data" panel. Optical center is often the center of image,
so it'll be filled in automatically.
You should also set values for undistortion (K1, K2 and K3). Currently,
there's no any visualization for this parameters and approach of
"change value -> reconstruct -> see what've changed" is the only way
for now.
Libmv team is working on auto-calibration tool, so it should be
easier to gather this coefficients in nearest (i hope) future.
There's also no scene orientation stuff.
Basic workflow:
- Open footage.
- Set markers and track them.
- Fill in camera data and keyframes.
- Hit "Solve Camera" button.
- Add "Camera Solver" constraint to camera in scene.
- Choose movieclip in that constraint.
- To see bundles in 3D viewport active clip should be set
in scene buttons.
===========================
- Internal changes:
* Fixed bundle.sh script to bundle libmv: it was generating
incorrect CMakeLists header.
* Rename CLIP_OP_delete to CLIP_OT_delete_track.
* Fixed crash when BKE_movieclip_acquire_ibuf is called
with NULL user.
* Made MovieTrackingMarker structure 8-bytes aligned
* Use writestruct rather than writedata for track markers.
This allows to change MovieTrackingMarker safely.
- Added "Delete Marker" operator which deletes marker for
current frame only. Hotkey is Shift-Del.
- Added MovieClip.size and MovieClip.resolution RNA properties.
Use last accessed frame number to get ImBuf from sequence.
- Added different actions for "Clear Path" operator:
* Clear path up to current frame.
* Clear the whole path.
* Cleat remained part of path (for frames after current).
- Changed buttons order and icons for tracking. New order is:
* Track frame backwards.
* Track sequence backwards.
* Track sequence forwards.
* Track frame forwards.
NOTE: this breaks compatibility with existing .blend files again,
but it should be much easier to change data structures without
breackaged in the future.
===========================
- Added missed stub for blenderplayer, so it should
compile again fine.
- libmv is added to extern/.
Script for bundling needed subset of sourcses from
libmv repo is included there.
- Eigen3 is also added to extern/.
libmv depends on Eigen3 (which isnt't compatible with Eigen2
from API point of view). So both of versions are going to
be in worktree for time (until code which used Eigen2 would be
ported to Eigen3).
- Added some functions to libmv-capi, so some things from
this library could already be used.
- Added the very basic implementation of 2D tracking.
It should be treated as draft for tracking architecture
which probably would be cleaned up, changed or whatever else.
Current implementation was supposed to demonstrate that our
structures and understading is correct to interact with libmv easily.
