===========================
- Fixed some silly things ni DNA design. Now all
reconstruction data is stored in Tracking->Reconstruction.
Please, re-solve your cameras -- reconstruction data
wouldn't be read from files saved in blender below this
commit.
- RNA accessors for reconstruction data.
- Store average reconstruction error in new reconstruction
structure and show it in clip editor header after
reconstruction.
- Highlight failed to reconstruct frames with red in cache line.
- Added "group" "Failed Tracks" in Select Grouped operator,
Meant to be used for selecting tracks bundles from which
failed to to be solved.
- Hotkey to delete marker: Shift-X.
- Jump to next/prev failed frame operator. Hotkeys are
Ctrl-Shift-Left/Right Arrow.
===========================
- Do not show frame boundary border when stabilization isn't enabled.
- Separate stabilization settings from display in clip editor.
Now clip can contain stabilization data but still be displayed
un-stabilized in clip editor.
- Internal changes in stabilization:
* Use separated location/scale parameters rather than 4x4 matrix.
In some ares "decomposed" data is needed (text draw functions, i.e.).
Also such decomposed data could be used in compositor.
* MovieClip now uses own structure for cache where additional data
can be stored. MovieCache structure now one of properties in
this new structure.
* Get rid of stable image buffer stored in MovieClipStabilization
structure. Pre-created buffer for scaling still stored there.
This helps to keep playback realtime -- re-creating this buffer
introduces ~15% slowdown.
- Added sliders to 2D stabilization panel which controls intensity
of translation/scale which applies on shot.
- Added filter type to Stabilize2D compositor node. Supports nearest,
bilinear and bicubic interpolation.
- After discussion with Sebastian and Francois added new node called
Transformation. It can apply translation, rotation and scale. It's
not the same thing as applying this components separately -- all
transformation is happening inside "canvas". And it should be more
accurate on interpolation and sub-pixel translation.
Need to check order of applying translation/scale/rotation btw.
- Added output sockets to movie clip compositor node. They holds
stabilization data which can be used by Translate or Transform
nodes.
- Minor fix of UI issues in Display panel.
===========================
Implemented 2D stabilization:
- Based on average point of several tracks.
- Tracks for stabilization are controllable from
"2D stabilization" panel.
- Implemented autoscaling. Could fail if average point is
too close to frame boundary.
- Background clip in 3D viewport and MovieClip input
compositor nodes are using stable shot.
Some internal weak things:
- Stable shots aren't cached in moviecache. There is
only one "slot" for stable shot inside stabilization
structure.
- This could fail if several threads are requested different
frames (for example when starting playback, pause to make
Nodes Editor trigger refresh, continue playback).
- Due to it shouldn't crash i decided to implement better
caching for stable shots a bit later.
===========================
- Fixed crash when transforming disabled marker.
- Select Inverse wouldn't select hidden parts of markers.
- Movie Clip display aspect ratio is now available on Display panel.
===========================
- Hide all reconreuction-related sliders from Display N-panel
of 3D viewport if "Show Reconstruction" is turned off.
- Added setting for shape of bundle. Default is sphere.
xsch and ysch were originally planed to replace the scene->r.xsch/r.ysch
however in blender/3dview we still need to use the r. values. Therefore we can't really run
from using those values even in bplayer. So removed the values in gamedata.
The way it's now, render values (xsch and ysch) are responsible for aspect ratio and gamedata xplay and yplay are responsible for the size of the window.
===========================
- Sliding from preview could now be undone.
- Fixed memory leak caused by NULL-ing used scopes on
layout restore.
- Fixed possible crash after splitting space clip.
* New object pointers can't be loaded properly for library linked groups, so the weight groups now store an index to the group objects at save time. This index is used at load time to set the objects without relying on the old pointers.
* If the library linked group is modified the indices can be wrong, but this can't really be avoided easily as there's no way to relate objects in a linked group between loads.
===========================
Commiting patch #24427: Editable camera sensor size (meaningful focal length units)
Thanks to:
Matt Ebb (author of original patch)
Ejner Fergo (porting patch through versions)
Brecht Van Lommel, Dalai Felinto, Campbell Barton (patch review)
Cant't commit changes to addons (they aren't branched, so some of them
could be broken now)
===========================
- 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.
Fix for bug #27710, 'Multires lost from 2.49 file in 2.5x'
Reported by Gaia Clary.
Problem was that the old multires data didn't flush changes to
vertices out to the Multires structure on filesave. So, recent bits of
sculpting could be lost if the multires level wasn't changed before
filesave.
We already had code to deal with missing multires vertex data, which
simply copies the Mesh vertex data into the multires vertex data if it
matches the number of vertices in the highest level. Moved this code
up a bit so that we always make this copy if the numbers match up.
Was able to reproduce the bug fresh in 2.49b, and confirmed that the
fix works. However, this does not help if changes were sculpted on a
multires level other than the highest level and saved without a
subsequent level change.
Usage currently is limited to:
- Panel text, widget text and label text style:
point size, shadow effects
Setting individual fonts to these is not possible yet, it uses the
default for it.
Access goes via outliner now; check "User Preferences". UI team could
add this in userpref scripts :)
In addition the billboards can be scaled by the particle velocity with optional head and tail factors (similar to line drawing options). This allows for pseudo-motionblur effects.
===========================
- Corrected copyrights in my new files header.
- Added debug option to dump as PNG image content of search
areas tracking between which was failed.
- Removed internal tracking settings like pyramid level and
tolerance. Weren't useful neither for me nor for artists.
- Fixed bug in BKE_tracking_get_marker which could lead
to failure of getting marker for current frame when
there's marker for requested frame.
- Fixed bug with disappearing markers after tracking for
cases when marker was added at frame different from
tracking start frame and tracking start frame is
equal to tracking end frame.
- Stop tracking when no markers could be tracked.
- Changed marker selection rules:
* If marker isn't selected, all it's areas are getting
selected with mouse.
* If marker is selected and selection type doesn't have
"extend" mode (SHIFT isn't holded down) the nearest
to mouse cursor area would be selected. All the reast areas
would loose selection.
- Limit number of frames which would be used in "Track Markers"
operator. So now you could easily track along 10/20/etc frames.
- Change scene current frame after "Track Markers" operator.
- Implemented speed limitors. Now tracking could happen:
* As fast as possible
* With reatime speed (scene FPS)
* With half of realtime speed
* With quarter of realtime speed.
- Got rid of orig_user in MovieTrackingContext and user
in TrackMarkersJob. This prevents crashes when user
joins some space to SpaceClip from which tracking was started.
- Made keyframes on path bigger and do not draw keyframes for
non-selected markers.
TODO: need to get rid of storing main, scene and screen
in TrackMarkersJob. This is needed to set scene's
current frame after tracking (such behavior is comfortable
for artists) but this could lead to crash if scene is
getting removed when tracking job is running.
Render animation operator also stores scene and main,
so such solution could be fine for first time before
we've got something smarter.
Vertex parents were not requesting the original index layer, now do this as
part of depsgraph building, and make constraints with vertex groups use the
same system. Fix is based on patch by Campbell, but with some changes.
##########
original name: "Allow to change the strenght of the "go behind" constraint of the camera actuator"
The camera actuator is an actuator that drive the camera to follow an object, with a set of constraint.
Currently, when the object followed rotate on himself (like a person, or an helicopter), the camera is really slow to go behind (at least 10 seconds).
This patch gives the UI to tweak the strenght of the 'go behind'[named damping] constraint.
###########
epydocs (rst) updated too
===========================
- Disallow moving pattern/search area in way when marker position is
outside of pattern area.
- MoiveClip could be set as background for 3D view.
Added background source property to BGPic to switch between image
and movie. Movie is a bit more complicaated entity than clip (due to
displaying bundles, test objects and so) that's why i've sliptted
background into two sources.
- Added Layout.template_movieclip to display general clip settings.
Used in Footage panel of SpaceClip and background image properties
in 3d view.
- Display bundles in 3D view as spheres. Selection is synchronized to
markers associated with this bundle.
Bundle can't be selected in 3D view.
- Recoded internal DNA structures, RNA and operators to match libmv entities.
Tracking data now consists of Tracks, each tracks consists of markers
which are associated with frame number. Markers holds position only,
pattern and search areas settings are stored in track. Such settings should
be unified for all markers in track and marker should hold position and
frame number only.
===========================
Implemented basic structures and operators for markers manipulaiton.
Markers contains:
- Position of marker at frame in unified 0..1 coordinates
- Relative positions of left-bottom and right-top corners of pattern area
- Relative positions of left-bottom and right-top corners of search area
- Selection flags
New operators:
- Create new maerker. It's a modal operator which creates markers
at mouse position when LMB is clicking.
- Delete selected markers.
- Select marker using RMB. Some parts of marker (point, patter, search)
could be deselected.
- Select markers using rectangular selection.
- Select markers using circle selection.
- Marker translation (G-key).
- Marker scaling (S-key).
UI changes:
- Added mode to space clip. Currently supported modes are:
* View mode
* Tracking mode
This was intended to separate different categories of tools,
so interface shouldn't be overheaded with plenty of tools
which aren't actually using in the same time.
- Created new panel when actiev tool is 'MARKER' and there's
active marker where positions could be adjusted in pixel space.
Internal changes:
- Splitted DNA/RNA movieclip files to make separation of
tracking data and movie data more clear. This could be useful
in the future when we'll want to support multiplie moies
for single camera tracking (to make tracking more accurate).
- Added new file in blenkernel, where all tracking-related function
would be stored. Not very much function here at this moment,
but in the future all stuff related on converting DNA to external
tracking data would be stored here.
- moved do_history into WM_write_file after successful write of .blend@ temporary file
- Added new file flag, to avoid writing history on writing the startup.blend, autosave files and undo.
Thanks Campbell, Brecht for review!
blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.
===========================
- Initial implementaiton of new ID named MovieClip.
Currently it has plactically the same functionality as
images, but this functionality would be widen in nearest future.
- Initial implementation of SpaceClip.
This space is supposed to be used for acting with MovieClips
(opening, playbacking, math-moving interaction and so on).
Currently you could open image sequence/movie file here, pan/zoom,
use a playback here.
I've added cache visualizer to this space, but it's currently more
a developer's feature to see how cache system works, but it could
be adopted for further artists' usage (something like cache visuzlizer
for simulations).
- Added new theme area for Space Clip.
No special colors were defined here yet.
- Implementation of basic cache system for movies.
This cache system is very familiar with sequence cache system,
but it supposed to be more portable: at least cache keys aren't
limited with sequence-based data and current seqcache could
became an interface between sequencer and moviecache without
much logic (only logic related on keys handling would be necessary
here).
Implemented basic limitors (ab\mount of cached imbuf's), so it'll
be a bit more difficult to go out of memory when playing long
animations in Image Editor (this cache system could be used for
images too, in the future).
- Very basic tools implementation -- only sceletion added, no
real tool implemented (only camera focal length added to the UI
which hasn't got real affect on anything).
Assorted notes:
- Not sure about best behaviour for Unlink clip button: should
it be imageeditor-like (with de-referencing only) or text-editor
like (with removing datablock from file).
- Also not sure if tools/properties should be splitted into
different areas or it'll be better to have tools and settings
for this tool/item/etc in the same area (tools at the top,
properties are under them).
Code for properties area is '#if 0'-ed.
- Sound isn't supported during playback in movie clip.
