In the case where the modifier stack didnt need deform-verts to calculate,
they would not be available for the preview either.
This fixes a bug caused by r57206 which set mirror to preview so the mirrored
weights would be displayed, but it only worked when there was an armature after it, see [#35545].
Hopefully it's more readable now. Took me a while to remmeber
all the stuff going on here while was looking into possibility
of implementing some feature here.
The tooltip seemed to hint that this tool is able to resolve all manner of
gimble-lock situations by untangling the curves (i.e. performing some kind of
equivalent-angles resolution, keeping in mind the nearest situations nearby).
However, this tool currently only performs corrections for the most basic case
when large jump+flip discontinuity artifacts appear in euler rotation curves as
a result of rotation values getting clipped to +/- 180 degrees, which arises
when these rotation curves are the result of baking some physics sim or so.
(Also, fixed an unrelated "replace-all" typo in a comment)
proposal was to add another special init hack for the viewer node->id, but rather would do it right and so moved all the special init hacks for constant ID backpointers (Scene for RenderLayer, Composite,
Defocus, FileOutput and MovieClip for MovieClip, MovieDistortion and Stabilization nodes). These are now part of the local init callbacks functions of the appropriate nodes, using the new initfunc_api
callback which takes a Context pointer, so they have access to Scene.
* Added a node to convert wavelength (in nanometers, from 380nm to 780nm) to RGB values. This can be useful to match real world colors easier.
* Code cleanup:
** Moved color functions (xyz and hsv) into dedicated utility files.
** Remove svm_lerp(), use interp() instead.

This is part of my GSoC 2013. (revisions 57322, 57326, 57335 and 57367 from soc-2013-dingto).
- BKE_mask_update_scene was only used with do_newframe=FALSE,
removed this argument.
- Made it so BKE_mask_update_scene is able to handle LIB_ID_RECALC_DATA
case. Namely, if mask ID is tagged for data update it means shapekeys
will be re-evaluated (as if do_newframe=true).
If mask id only tagged for LIB_ID_RECALC, then no shapekey evaluation
happens (same as it used to behave before).
This means, doing DAG_id_tag_update(&mask->id, OB_RECALC_DATA) will
lead to shapekeys re-evaluation which is really needed in such
operators as clearing shapekeys (and cleaning shapekeys which is
in tomato branch yet).
This is a bit silly to use OB_RECALC_DATA sine mask is not an OB,
but could not see better way to do it now.
This fixes missing mask re-evaluation after clearing shapekey,
would expect no other functional changes.
The "Multiply" blending mode for NLA strips worked incorrectly. Instead of
modulating the influence of the current strip, it was in fact scaling the result
of the entire stack (with the strip applied). This caused problems when
influence = 0, as it was in fact muting everything instead of just controlling
the strip we are interested in.
have zero total influence
Previously, when evaluating the NLA stack at a particular point in time, if a
channel hadn't been encountered before, influence values were simply ignored
when accumulating the values contributed by each strip to the overall stack.
This behaviour simplified the handling of the problem of what "baseline" to
blend relative to (i.e. influence basically scales the magnitude of a scalar
around 0, but we may not exactly want a property to get it's value set to 0 as
baseline). However, the problem was that this meant that you'd get popping
artifacts when the a lower strip finally reaches influence=0 but your upper
strips haven't fully reached maximum yet ([#35382]). Another problem was that
you'd end up with less ability to scale the influence of all strips (as in
[#35263]).
So, as a stop-gap fix now, we will allow influence scaling to work on these
strips too. This still doesn't fix some of the other problems regarding
baselines/rest-poses and deterministic behaviour when some channels are only
keyed in one strip which isn't set to extend it's influence... Fixing those
issues is a bit more involved, and would require a bit of refactoring of how we
keep track of accumulation channels.
- script execution is off by default
- if a blend file attempts to execute a script
this shows a message in the header with the action
that was suppressed (script/driver/game-autostart) and 2 buttons to either reload the file trusted, or to ignore the message.
- the file selector will always default to use the trust setting in the user preferences,
but reloading an open file will keep using the current setting (whatever was set before or set on the command-line).
- added SCons setting WITH_BF_PYTHON_SECURITY, this sets the default state for the user prefereces not to trust blend files on load.
... this option was in CMake before, but always off, now its enabled by default for SCons and CMake, and forced on in CMake for now.

ToDo:
* Move some functions into an util file, maybe a common util_color.h or so.
* Test GPU, unfortunately sm_21 doesn't work for me yet.
* CHARTAB: not needed anymore with improved copy/paste support and text input.
* IDPOIN: replaced by SEARCH_MENU.
* ICONROW/ICONTEXTROW: replaced by RNA enums.
* NUMABS: can use min/max limits instead.
* BUT_TOGDUAL, TOG3, TOGR, SLI: not used in 2.5 interface.
offsets too (like for location)
This is useful in some cases when Copy Rotation constraints would otherwise be
used for this purpose but cannot be used for various reasons. Basically, this
works in practically the same way that the Copy Rotation offsets work, including
the same weirdness that you'll get when trying to manually rotate these in the
3D viewport using "global" space manipulations ("local/normal" spaces though
still seem to work really nicely).
WARNING: this may potentially break old files with transform constraint setups
involving rotation outputs. Please check whether this causes any problems on old
files, and report back if there are any issues.
If multires has got zero subdivisions in sculpt mode, no need
of displaying warning message. It was rather strange decision
which confused artists.
Now multires with zero subdivisions will be ignored silently
when in sculpt mode.
add arguments to calculate normals when converting to bmesh:
BM_mesh_bm_from_me, DM_to_bmesh
This gives some speedup to undo (which didnt need to re-calculate vertex normals), and array modifier which doesnt need to calculate face normals at all
An optional 'internal' argument was added to the bpy.data.texts.load() operator.
The changes in revision 57153 were reverted, so that the is_in_memory and is_dirty
properties of text datablocks are not editable again.
In the C API layer, BKE_text_load_ex() was introduced to allow for optionally
making text datablocks internal after loading.
Now add asserts to make sure this layer is only added once the modifier stack has been calculated.
this saves normal layer being calculated whenver vertex normals need updating.
many modifiers were calculating normals, when those normals were ignored by the next modifier.
now flag normals as dirty and recalculate for modifiers that set use `dependsOnNormals()` callback.
Quick test on mesh with 12 modifiers (mostly build type), calculated normals 6 times, now it only runs once - so this will give some speedup too.
Implements an automatic keyframe selection algorithm which uses
couple of approaches to find out best keyframes candidates:
- First, slightly modifier Pollefeys's criteria is used, which
limits correspondence ration from 80% to 100%. This allows to
reject keyframe candidate early without doing heavy math in
cases there're not much common features with first keyframe.
- Second step is based on Geometric Robust Information Criteria
(aka GRIC), which checks whether features motion between
candidate keyframes is better defined by homography or
fundamental matrices.
To be a good keyframe candidate, fundamental matrix need to
define motion better than homography (in this case F-GRIC will
be smaller than H-GRIC).
This two criteria are well described in this paper:
http://www.cs.ait.ac.th/~mdailey/papers/Tahir-KeyFrame.pdf
- Final step is based on estimating reconstruction error of
a full-scene solution using candidate keyframes. This part
is based on the following paper:
ftp://ftp.tnt.uni-hannover.de/pub/papers/2004/ECCV2004-TTHBAW.pdf
This step requires reconstruction using candidate keyframes
and obtaining covariance matrix of 3D points positions.
Reconstruction was done pretty much straightforward using
other simple pipeline routines, and for covariance estimation
pseudo-inverse of Hessian is used, which is in this case
(J^T * J)+, where + denotes pseudo-inverse.
Jacobian matrix is estimating using Ceres evaluate API.
This is also crucial to get rid of possible gauge ambiguity,
which is in our case made by zero-ing 7 (by gauge freedoms
number) eigen values in pseudo-inverse.
There're still room for improving and optimizing the code,
but we need some point to start with anyway :)
Thanks to Keir Mierle and Sameer Agarwal who assisted a lot
to make this feature working.
