- 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.
* VERTEX_WEIGHT modifiers had quite a messy UI, improved the grouping of options a bit, so it is easier to scan through.
* Do not use abbreviations like "Rem" or "Dist" in the UI...
* Also small change for BEVEL modifier UI for more efficient space usage.
- Ctrl+RMB only worked for edges & faces
- Menu item 'Select Shortest Path' only worked for vertices.
Now Ctrl+RMB works for vertices and the menu item works for verts/edges/faces (depending on the current selection).
- expose unwrap as a menu (rather then a regular button that pops up a menu)
- move 2 extrude buttons into one menu button, also do the same for the mesh menu.
Now button in the toolshelf behaves this way:
- User clicks on "Add Marker"
- Then he clicks where the marker should get placed

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.
The Emission panel now has a Use Modifier Stack option to emit particles from
the mesh with modifiers applied. Previously particles would only be emitted from
faces that exist in the original mesh. There are some caveats however:
http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.68/Tools#Particles
Use center of currently visible frame part instead of
center of the whole frame for position of marker which
is adding from toolbox.
Used separate operator for this to keep operators more
atomic and not confuse with lots of conflicting properties.
Previously it was nearly impossible to have fast moving objects emitting smoke or they would just leave behind a row of smoke poofs instead of continious stream of smoke. Now it's possible to set number of subframes for each smoke flow.
Another new thing is ability to set size of smoke flow particles instead of using closest smoke cell. This also works with my earlier "full sample" commit, so no more blocky particles either. :)
For more info check my blog post: http://www.miikahweb.com/en/blog/2013/05/17/blender-smoke-subframes
This commit also includes couple of fixes I spotted while testing:
* Fix: dissolve was applied at different time for low res and high res simulations.
* Fix: full sample setting didn't get copied with domain.
So now, in the new "other" tex context, you can (depending on active data) have direct access to modifiers', force's or brushes' textures...
I also refactored a bit how texture contexts are handled (once again, we had some quite similar code in both space_buttons and RNA sources). This should also solve some harmless glitches like "no texture context selected in UI" sometimes when you remove data related to current texture (see e.g. after removing the material from default cube, in startup scene).
This usage of two different systems for textures, and the handling of switches between them, has been a bit tricky to get working right, but it is OK now I think. I also had to add a bool flag to buttons space, SB_TEX_USER_LIMITED (use_limited_texture_context in RNA), which indicates "new shading" texture code whether it has to ignore materials, lamps etc. (BI) or not (Cycles).
Btw, pinned textures from modifiers/force/etc. were also broken (showing nothing), now it should work too.
Thanks to Brecht for reviewing.
bug reported by Eloy Felix over email
Apparently there are some files that will perform better with "use_occlusion_culling" off.
For now the UI option can return.
Technically this could make into 2.67a, but the string is not localized (it'll be in English).
Not sure what is more important here:
- consistent UI OR to expose in the UI an option some people need
* Editing number of segments for particle hair did not update the viewport.
* Hidden particles were confusing, the paths were drawn but without the points.
Now it draws the path faded to indicate that they are hidden/locked.
* Select tips/roots operators now have options to select/deselect/toggle/invert.
This operator will run a tracker from previous
keyframe to current frame for all selected markers.
Current markers positions are considering initial
position guess which could be updated by a tracker
for better match.
Useful in cases when feature disappears from the
frame and then appears again. Usage in this case
is the following:
- When feature point re-appeared on frame, manully
place marker on it.
- Use Refine Markers operation (which is in Track
panel) to allow tracker to find a better match.
Depending on direction of tracking use either
Forwards or Backwards refining. It's easy: if
trackign happens forwards, use Refine Frowards,
otherwise use Refine Backwards :)
This is hopefully the ultimate solution against smoke blockiness near emitter.
Previously high resolution flow/emitter voxels were generated based on the low resolution ones. So if you had 32 resolution and 4 division high resolution, it still used smoke flow generated from those 32 resolution voxels. Now I introduced a new sampling method called "Full Sample" that generates full resolution flow for for high resolution domain as well.
Read more about it in my blog post: https://www.miikahweb.com/en/blog/2013/05/10/getting-rid-of-smoke-blockiness
Also changed "quick smoke" operator default voxel data interpolation mode to "Cubic B-Spline" to smoothen out it even more.
This is an alternative to using camera to scale the
scene and it's expected to be better solution because
scaling camera leads to issues with z-buffer.
Found the whole scaling thing a bit confusing,
especially for object tracking, but cleaning this up
is a bit different topic.
Moved the code after the masking check so we can skip the texture lookup
if the pixel is done, is a bit faster. Also hide the color wheel for these
tools, only did it for 2D paint in previous commit.
* 2D image painting with textures that contained alpha did not work correctly,
had been broken for a while.
* 2D image panels texture (mask) panels showed wrong buttons for texture overlay.
* Texture map mode 3D now also uses masking, like Tiled and Stencil the texture
does not move along with the brush so it works fine.
* 2D image paint View mapping did not work correct, especially noticeable with
Rake rotation.
* Masking is now disabled for the smear tool, this can't really work because
the original image is constantly changing and gave artifacts.
scaling it along one axis, now there's a Reset Transform button.
The Image Aspect button is now also hidden unless the texture is an image texture.
And also hide the color wheel for painting tools that don't use colors.
* 2D image painting support for masking to limit the max contribution of a stroke
to a pixel, to get it working compatible with projection painting. Not strictly
a bugfix, but the inconsistency here was annoying.
* Fix python errors in Texture Mask panel in image editor, was missing overlay
options.
* Clamp paint mask to 0..1 in case some texture exceeds it, this could give black
pixels due to integer overflow.
Since the bug was fixed that made blur brush _not_ blur all verts, there is no way to blur vertex colors after baking.
While this was hidden it was useful especially for baking vertex colors.
