===========================
- 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.
===========================
- 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.
===========================
- Removed unneeded checking of marker==NULL
- Tracks could be named now.
- Implemented "Follow Track" constraint to "parent"
objects to tracks from movie clip.
- Added operator to create such constraint for active object
using clip and track from current context.
Committing here a patch by Bastien Montagne (mont29), a more understandable Translation Constraint UI.
Before: http://www.pasteall.org/pic/12578
Now http://www.pasteall.org/pic/12258
From the description:
"When you set “X” under the Destination’s “Z”, it does not mean that the Z transform of the source should affect the X transform of the destination, but rather that the X transform of the source should affect the Z transform of the destination…"
The new UI should make it a bit more clear.
ui/ --> startup/bl_ui
op/ --> startup/bl_operators
scripts/startup/ is now the only auto-loading script dir which gives some speedup for blender loading too.
~/.blender/2.56/scripts/startup works for auto-loading scripts too.
