===========================
- 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.
* 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.
===========================
- 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.
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 :)
===========================
- 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!
===========================
- 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.
- when saving blend file with 'Remap Relative' enabled, don't try make paths absolute if the internal filename is invalid.
- use case insensitive path comparison on windows when checking if path remapping is needed & for comparing next/prev dirs in the file selector.
- rename 'name', 'dir' --> 'filepath' where these actually represent a file path to avoid confusion.
- bugfix for possible (but unlikely) uninitialized string.
- remove commented script append function, now we have a python api for this.
simple modifier, almost like a hook, except it can deform with 2 object source -> target, has option to preserve rotation and use different falloff types.
Made some improvements to the point density texture. Added support
for tweaking the falloff with a custom curve. Also coded new
falloff types based on the age or velocity of particles.
Also added a test break check to the volumetric shade cache code,
to avoid nasty hangups from the preview render (on render, exit,
etc).
Envelope FModifier data points were getting saved in a non-portable
way. Apparently this broke when trying to read files with this data on
PPC machines if the files were saved using Intel machines.
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.
* Effecting particle properties with textures was possible in 2.49,
but not in 2.5 anymore.
* Now particles have their own textures (available in texture panel
for objects with particle systems), which are totally separate from
the material textures.
* Currently a basic set of particle properties is available for
texture control. Some others could still be added, but the whole
system is not intended as an "change anything with a texture" as
this kind of functionality will be provided with node particles in
the future much better.
* Combined with the previously added "particle texture coordinates"
this new functionality also solves the problem of animating particle
properties through the particle lifetime nicely.
* Currently the textures only use the intensity of the texture in
"multiply" blending mode, so in order for the textures to effect
a particle parameter there has to be a non-zero value defined for
the parameter in the particle settings. Other blend modes can be
added later if they're considered useful enough.
* Viscoelastic springs between the fluid particles can simulate all kinds
of viscous and elastic substances, such as jelly and honey. This is
achieved by creating springs dynamically between neighboring particles
and adjusting their rest length based on stretching/compression.
* This nearly completes the currently intended functionality for particle
fluids. The last missing thing is a surfacing extraction algorithm,
which is needed for a proper representation of a sph fluid.
* I also cleaned up and renamed some of the fluid parameters to make the
ui a bit easier to understand.
* One addition to the patch is an option to use "initial rest length" for
the springs, which uses the lengths between the particles at the time of
spring creation as the spring rest lengths instead of interaction radius/2.
This makes the fluid keep it's original shape better (good for very
viscoelastic materials), but can create large density differences inside
the fluid (not really physically correct for a fluid).
* Viscoelastic springs are stored in point cache as extra data.
* Not strictly necessary right now, but better for future.
* Struct data (only boids at the moment) is now written as structs (with dna) so they work between 64 and 32 bit machines too.
* I've getting bad feelings about the point cache index_array for a while (cause for this bug too), so from now on memory cache uses a simple binary search directly on the index data to handle queries to specific data points.
* This is a bit slower than just checking from a dedicated array, but it's much less error prone, uses less memory and makes the code more readable too, so it's not a tough choice.
This allows manual (point by point) animation of their control verts,
although many other settings cannot really be animated with any
visible effects yet. Interestingly, lattices also had IPO block
pointers, though they were never really used (AFAIK).
Todo:
- Animation Editor support has yet to be added. I've got a few other
things to add to, so will group those changes together.
- skip fixing file paths on undo.
- simplify bpath alloc and free functions, also pass Main structure so as not to rely on G.main, (needed for file load).
- use sizeof() in more places.
- fixed some off by 1 bugs copying strings. setting curve font family for instance was 1 char too short.
- replace strncpy and strcpy with BLI_strncpy
Both stored the filename of the blend file, but G.sce stored the last opened file.
This will make blender act differently in some cases since a relative path to the last opened file will no longer resolve (which is correct IMHO since that file isnt open and the path might not even be valid anymore).
Tested linking with durian files and rendering to relative paths when no files is loaded however we may need to have some operators give an error if they are used on the default startup.blend.
- made interface, windowmanager, readfile build without unused warnings.
- re-arranged CMake's source/blender build order so less changed libs are build later, eg: IK, avi
from Mathew Burrack (mburrack)
...also applied a fix so this flag wont be written but including this patch for older startup.blend's.
--- from the tracker
I've created a patch for the texture path corruption bug, 23337. Basically, G_FILE_RELATIVE_REMAP was improperly getting
saved out to the startup.blend file, causing issues when the autosave timer went off. The proper fix is to mask out
that flag so it doesn't get written out to .blend files itself, but since that doesn't fix any pre-existing startup.blend
files, I just mask it out when startup.blend is read in instead.
I've tested it locally and so far, it seems to fix all the issues I've had with texture image paths getting corrupted.
I haven't figured out how to properly test the remap-on-save option in the save as dialog, though, so I don't know if
I accidentally broke that or not (although I don't see how I could have).
