BKE_depsgraph.h
This removes BKE_depsgraph.h and depsgraph.c
|
|
- Add blentranslation `BLT_*` module.
- moved & split `BLF_translation.h` into (`BLT_translation.h`, `BLT_lang.h`).
- moved `BLF_*_unifont` functions from `blf_translation.c` to new source file `blf_font_i18n.c`.

I'd kept the code around in the codebase until after the merge back to master
to avoid having too many conflicts if things changed there (or in case we
needed to roll back). Now, it's safe to jettison this!

This merge-commit brings in a number of new features and workflow/UI improvements for
working with Grease Pencil. While these were originally targetted at improving
the workflow for creating 3D storyboards in Blender using the Grease Pencil,
many of these changes should also prove useful in other workflows too.
The main highlights here are:
1) It is now possible to edit Grease Pencil strokes
- Use D Tab, or toggle the "Enable Editing" toggles in the Toolbar/Properties regions
to enter "Stroke Edit Mode". In this mode, many common editing tools will
operate on Grease Pencil stroke points instead.
- Tools implemented include Select, Select All/Border/Circle/Linked/More/Less,
Grab, Rotate, Scale, Bend, Shear, To Sphere, Mirror, Duplicate, Delete.
- Proportional Editing works when using the transform tools
2) Grease Pencil stroke settings can now be animated
NOTE: Currently drivers don't work, but if time allows, this may still be
added before the release.
3) Strokes can be drawn with "filled" interiors, using a separate set of
colour/opacity settings to the ones used for the lines themselves.
This makes use of OpenGL filled polys, which has the limitation of only
being able to fill convex shapes. Some artifacts may be visible on concave
shapes (e.g. pacman's mouth will be overdrawn)
4) "Volumetric Strokes" - An alternative drawing technique for stroke drawing
has been added which draws strokes as a series of screen-aligned discs.
While this was originally a partial experimental technique at getting better
quality 3D lines, the effects possible using this technique were interesting
enough to warrant making this a dedicated feature. Best results when partial
opacity and large stroke widths are used.
5) Improved Onion Skinning Support
- Different colours can be selected for the before/after ghosts. To do so,
enable the "colour wheel" toggle beside the Onion Skinning toggle, and set
the colours accordingly.
- Different numbers of ghosts can be shown before/after the current frame
6) Grease Pencil datablocks are now attached to the scene by default instead of
the active object.
- For a long time, the object-attachment has proved to be quite problematic
for users to keep track of. Now that this is done at scene level, it is
easier for most users to use.
- An exception for old files (and for any addons which may benefit from object
attachment instead), is that if the active object has a Grease Pencil datablock,
that will be used instead.
- It is not currently possible to choose object-attachment from the UI, but
it is simple to do this from the console instead, by doing:
context.active_object.grease_pencil = bpy.data.grease_pencil["blah"]
7) Various UI Cleanups
- The layers UI has been cleaned up to use a list instead of the nested-panels
design. Apart from saving space, this is also much nicer to look at now.
- The UI code is now all defined in Python. To support this, it has been necessary
to add some new context properties to make it easier to access these settings.
e.g. "gpencil_data" for the datablock
"active_gpencil_layer" and "active_gpencil_frame" for active data,
"editable_gpencil_strokes" for the strokes that can be edited
- The "stroke placement/alignment" settings (previously "Drawing Settings" at the
bottom of the Grease Pencil panel in the Properties Region) is now located in
the toolbar. These were more toolsettings than properties for how GPencil got drawn.
- "Use Sketching Sessions" has been renamed "Continuous Drawing", as per a
suggestion for an earlier discussion on developer.blender.org
- By default, the painting operator will wait for a mouse button to be pressed
before it starts creating the stroke. This is to make it easier to include
this operator in various toolbars/menus/etc. To get it immediately starting
(as when you hold down DKEy to draw), set "wait_for_input" to False.
- GPencil Layers can be rearranged in the "Grease Pencil" mode of the Action Editor
- Toolbar panels have been added to all the other editors which support these.
8) Pie menus for quick-access to tools
A set of experimental pie menus has been included for quick access to many
tools and settings. It is not necessary to use these to get things done,
but they have been designed to help make certain common tasks easier.
- Ctrl-D = The main pie menu. Reveals tools in a context sensitive and
spatially stable manner.
- D Q = "Quick Settings" pie. This allows quick access to the active
layer's settings. Notably, colours, thickness, and turning
onion skinning on/off.

Make the UI API more consistent and reduce confusion with some naming.
mainly:
- API function calls
- enum values
some internal static functions have been left for now
|
|
|
|
Opted to keep includes if they are used indirectly (even if removing is possible).
|
|
This deduplicates/simplifies some code. Also cleanup up a bit scopes UI code!
Use new GRIP button for uiList grab-resize.
This allows us to greatly simplifies the code, and get rid of a few hacks in uiList event handling!
Note autosize mode of uiList is now trigered by any value of list_grip below a given threshold, rather than the fixed zero value...

- Display additional information about channels
and buffer type (float/byte).
- Don't show frame number beyong sequence length.
- Also fixed issues with footage length calculation,
so it's pronbably will be needed to reload some
of existing footages.

Displays such information as current frame dimension,
frame number within image sequence/movie and in case
of image sequence input displays current file name of
a frame.
Not entirely happy with such approach, but was requested
a lot by artists.

With the view3d 'Render Only' option, grease pencil wouldn't draw, but for OpenGL render it did.
Since grease pencil can be very useful in opengl renders, enable grease pencil drawing with 'Render Only' option in the viewport,
and add a checkbox in the grease pencil header not to draw (unchecking each layer is annoying and applies to all spaces).

Replace old color pipeline which was supporting linear/sRGB color spaces
only with OpenColorIO-based pipeline.
This introduces two configurable color spaces:
- Input color space for images and movie clips. This space is used to convert
images/movies from color space in which file is saved to Blender's linear
space (for float images, byte images are not internally converted, only input
space is stored for such images and used later).
This setting could be found in image/clip data block settings.
- Display color space which defines space in which particular display is working.
This settings could be found in scene's Color Management panel.
When render result is being displayed on the screen, apart from converting image
to display space, some additional conversions could happen.
This conversions are:
- View, which defines tone curve applying before display transformation.
These are different ways to view the image on the same display device.
For example it could be used to emulate film view on sRGB display.
- Exposure affects on image exposure before tone map is applied.
- Gamma is post-display gamma correction, could be used to match particular
display gamma.
- RGB curves are user-defined curves which are applying before display
transformation, could be used for different purposes.
All this settings by default are only applying on render result and does not
affect on other images. If some particular image needs to be affected by this
transformation, "View as Render" setting of image data block should be set to
truth. Movie clips are always affected by all display transformations.
This commit also introduces configurable color space in which sequencer is
working. This setting could be found in scene's Color Management panel and
it should be used if such stuff as grading needs to be done in color space
different from sRGB (i.e. when Film view on sRGB display is use, using VD16
space as sequencer's internal space would make grading working in space
which is close to the space using for display).
Some technical notes:
- Image buffer's float buffer is now always in linear space, even if it was
created from 16bit byte images.
- Space of byte buffer is stored in image buffer's rect_colorspace property.
- Profile of image buffer was removed since it's not longer meaningful.
- OpenGL and GLSL is supposed to always work in sRGB space. It is possible
to support other spaces, but it's quite large project which isn't so
much important.
- Legacy Color Management option disabled is emulated by using None display.
It could have some regressions, but there's no clear way to avoid them.
- If OpenColorIO is disabled on build time, it should make blender behaving
in the same way as previous release with color management enabled.

- Re-arrange functions in headers and implementation file to make them
more grouped by entity they're operating with. Also order of functions
in implementation file should match order of functions in header for
easier navigation.
- Rename some functions to match conventions of naming public functions.
- Some code de-duplication, still some room for improvements tho.
- Split main 2D tracking functions into smaller steps to make it more clear.
Accidentally OpenMP was disabled in some of previous commits, re-enable it.

===========================================
Major list of changes done in tomato branch:
- Add a planar tracking implementation to libmv
This adds a new planar tracking implementation to libmv. The
tracker is based on Ceres[1], the new nonlinear minimizer that
myself and Sameer released from Google as open source. Since
the motion model is more involved, the interface is
different than the RegionTracker interface used previously
in Blender.
The start of a C API in libmv-capi.{cpp,h} is also included.
- Migrate from pat_{min,max} for markers to 4 corners representation
Convert markers in the movie clip editor / 2D tracker from using
pat_min and pat_max notation to using the a more general, 4-corner
representation.
There is still considerable porting work to do; in particular
sliding from preview widget does not work correct for rotated
markers.
All other areas should be ported to new representation:
* Added support of sliding individual corners. LMB slide + Ctrl
would scale the whole pattern
* S would scale the whole marker, S-S would scale pattern only
* Added support of marker's rotation which is currently rotates
only patterns around their centers or all markers around median,
Rotation or other non-translation/scaling transformation of search
area doesn't make sense.
* Track Preview widget would display transformed pattern which
libmv actually operates with.
- "Efficient Second-order Minimization" for the planar tracker
This implements the "Efficient Second-order Minimization"
scheme, as supported by the existing translation tracker.
This increases the amount of per-iteration work, but
decreases the number of iterations required to converge and
also increases the size of the basin of attraction for the
optimization.
- Remove the use of the legacy RegionTracker API from Blender,
and replaces it with the new TrackRegion API. This also
adds several features to the planar tracker in libmv:
* Do a brute-force initialization of tracking similar to "Hybrid"
mode in the stable release, but using all floats. This is slower
but more accurate. It is still necessary to evaluate if the
performance loss is worth it. In particular, this change is
necessary to support high bit depth imagery.
* Add support for masks over the search window. This is a step
towards supporting user-defined tracker masks. The tracker masks
will make it easy for users to make a mask for e.g. a ball.
Not exposed into interface yet/
* Add Pearson product moment correlation coefficient checking (aka
"Correlation" in the UI. This causes tracking failure if the
tracked patch is not linearly related to the template.
* Add support for warping a few points in addition to the supplied
points. This is useful because the tracking code deliberately
does not expose the underlying warp representation. Instead,
warps are specified in an aparametric way via the correspondences.
- Replace the old style tracker configuration panel with the
new planar tracking panel. From a users perspective, this means:
* The old "tracking algorithm" picker is gone. There is only 1
algorithm now. We may revisit this later, but I would much
prefer to have only 1 algorithm. So far no optimization work
has been done so the speed is not there yet.
* There is now a dropdown to select the motion model. Choices:
* Translation
* Translation, rotation
* Translation, scale
* Translation, rotation, scale
* Affine
* Perspective
* The old "Hybrid" mode is gone; instead there is a toggle to
enable or disable translation-only tracker initialization. This
is the equivalent of the hyrbid mode before, but rewritten to work
with the new planar tracking modes.
* The pyramid levels setting is gone. At a future date, the planar
tracker will decide to use pyramids or not automatically. The
pyramid setting was ultimately a mistake; with the brute force
initialization it is unnecessary.
- Add light-normalized tracking
Added the ability to normalize patterns by their average value while
tracking, to make them invariant to global illumination changes.

- Displays dopesheet information for selected tracks, and currently does not
support any kind of editing.
- Changed regions to use the whole main region for such views as curves and dopesheet.
This allows to have own panels with tools/properties in this area.
- Active clip is getting synchronized between different clip editor editors in the
same screen, so updating of curve/dopesheet views happens automatically when one
changes current clip in one of this editors.
- Panels in toolbox and properties panels are now separated to rely on current view
mode, but some operators and poll functions still need to be updated.
- Added new screen called "Movie Tracking" where layout is configured to
display timeline, main clip window, curves and dopesheet.

===========================
Commiting camera tracking integration gsoc project into trunk.
This commit includes:
- Bundled version of libmv library (with some changes against official repo,
re-sync with libmv repo a bit later)
- New datatype ID called MovieClip which is optimized to work with movie
clips (both of movie files and image sequences) and doing camera/motion
tracking operations.
- New editor called Clip Editor which is currently used for motion/tracking
stuff only, but which can be easily extended to work with masks too.
This editor supports:
* Loading movie files/image sequences
* Build proxies with different size for loaded movie clip, also supports
building undistorted proxies to increase speed of playback in
undistorted mode.
* Manual lens distortion mode calibration using grid and grease pencil
* Supervised 2D tracking using two different algorithms KLT and SAD.
* Basic algorithm for feature detection
* Camera motion solving. scene orientation
- New constraints to "link" scene objects with solved motions from clip:
* Follow Track (make object follow 2D motion of track with given name
or parent object to reconstructed 3D position of track)
* Camera Solver to make camera moving in the same way as reconstructed camera
This commit NOT includes changes from tomato branch:
- New nodes (they'll be commited as separated patch)
- Automatic image offset guessing for image input node and image editor
(need to do more tests and gather more feedback)
- Code cleanup in libmv-capi. It's not so critical cleanup, just increasing
readability and understanadability of code. Better to make this chaneg when
Keir will finish his current patch.
More details about this project can be found on this page:
http://wiki.blender.org/index.php/User:Nazg-gul/GSoC-2011
Further development of small features would be done in trunk, bigger/experimental
features would first be implemented in tomato branch.
