- Nearest interpolation was always used when there's
no rotation for stabilization. Was a failure of
optimization heuristic.
- Made 2d stabilization frame acquiring threaded.
This function is only used for display and sequencer
which will only benefit of threads here.
- Fixed bug introduced in r48749 which lead to
re-making stable frame on every redraw.
Since we use the rigid body transform when transforming rigid bodies
things like parents and constraints add an offset because rigid body
transforms are in global space.
Now we just don't take rigid body transform into account on simulation
start frame so there are no problems when doing the initial setup.
The problem still exists when simulation is running of course.
To properly fix this we'd have to solve parenting and constratins while
taking rigid bodies into account before and after transform.
We'll have to see if it's really needed, would like to avoid it though.
This commit is the first part of a two-part merger of the soc-2008-mxcurioni
(Freestyle) branch. New 'freestyle' folders were added to the source/blender/
and release/script/ directories through a couple of svn copy operations
(instead of svn merge, due to broken svn:mergeinfo properties of the branch).
This made preview working but that broke internals
of tracking.
Namely, BlurredImageAndDerivativesChannels is giving
much more blurred image because it was assuming pixel
center is an integer position.
Guess other parts of libmv used to suffer because of
this issue.
Now pixel centering happens in blender side, and
libmv assumes integer position is a pixel center.
Deprecated Freestyle-specific elements were removed from the code base,
in order to address all comments from branch code reviews.

Backward compatibility won't be maintained in the following components:
- Freestyle edge/face marks in old .blend files are ignored.
Old .blend files can be converted by loading and saving the files using
a Freestyle branch build between revision 55581 and 55842.
- External style modules are no longer supported.
Instead text datablocks must be used to keep style module files within
.blend files. A branch build between revision 55741 and 55842 is useful
for identifying the style module file names that need reconfiguring.
The removed code was necessary due to a logical bug in the use of CD_ORIGINDEX
layer entries. Previously the index values were used to refer to the edges/polys
of the derived mesh, assuming that the derived mesh edges/polys consisted of those
from the original mesh plus newly added edges/polys. This assumption was not
correct, although it worked well for several modifiers such as Mirror and Solidify.
Now the index values are specifically used to reference the edge/polys of the
original mesh.
modifiers with text/curve/surface objects.
This is because the code here did not yet support the distinction between
generating the tesselated mesh at viewport/render resolution and generating a
separate displist/derivedmesh for render that is not stored in the object but
created and freed on the fly.
- When changing clip in clip editor, remove all frames
from it's cache to free memory for new clip.
- When changing proxy render settings, free cache as well.
Made it an operator instead of automatic prefetching.
Filling the whole memory with frames is not always
desired behavior.
Now prefetching is available via P-key, or from Clip
panel in toolbox or from Clip menu.
Also enabled prefetching for non-proxied movies.
Suggested by Brecht Van Lommel and Campbell Barton through code review comments.
Previously style modules were external Python script files whose absolute paths
were kept in .blend files. Now style modules are stored in .blend files as text
datablocks.
Style modules are configured in three steps:
1. Open an external style module file (or create a new text datablock) in the
Text Editor in Blender.
2. Add a style module to the list of style modules (by pressing the "Add" button)
in the Render Layer properties window.
3. Click the name entry and select the style module from the drop-down menu.
The Scopes and Histogram (Image editor, Sequencer) were not updating on
changes in color or display settings.
- Missing notifiers for refreshing
- Missing code to draw correct for managed byte buffers.
Added a sanity check to the ED_node_link_insert function to ensure it exits gracefully if no suitable sockets can be found. This was the problem with custom pynodes, which don't define the 'type' DNA of old sockets. The operator will have to be generalized for future nodes, but for now just not crashing seems good enough.
Script node crashes in #34810 were caused by uninitialized 'type' integer as well. This is now done in the set_typeinfo function for sockets (like for trees and nodes too), to avoid any potential remaining issues of this kind. Note that new files need to be loaded and saved again once to be forward compatible again.
well as I would like, but it works, just add a subsurface scattering node and
you can use it like any other BSDF.
It is using fully raytraced sampling compatible with progressive rendering
and other more advanced rendering algorithms we might used in the future, and
it uses no extra memory so it's suitable for complex scenes.
Disadvantage is that it can be quite noisy and slow. Two limitations that will
be solved are that it does not work with bump mapping yet, and that the falloff
function used is a simple cubic function, it's not using the real BSSRDF
falloff function yet.
The node has a color input, along with a scattering radius for each RGB color
channel along with an overall scale factor for the radii.
There is also no GPU support yet, will test if I can get that working later.

Implementation notes:
http://wiki.blender.org/index.php/Dev:2.6/Source/Render/Cycles/Subsurface_Scattering
Most changes in revision 55228 were reverted and Freestyle edge/face marks
were re-implemented using CD_ORIGINDEX layers of edge/poly custom data.
For this implementation to work properly, modifiers were updated so that
required CD_ORIGINDEX layers will be set. As pilot cases, the Mirror and
Solidify modifiers were updated (see comments in the code).
Some Freestyle-specific code is necessary in DerivedMesh.c so that the
CD_FREESTYLE_EDGE/FACE layers will be transferred from meshes to derived
meshes. This seems unnecessary, so further investigation is foreseen.
Stencil style texture mapping. Ready for field testing and user feedback.
This commit adds stencil like brushes, like those that existed on old ptex branch.
(with the exception of clip colour)
To control the position of the stencil, you use
Q: translation
Shift - Q: scaling
Ctrl - Q: rotation
There's extra work that has been done to make this work:
* Support for coloured overlay in vertex/texture painting
* Also made A button do stroke mode selection like in sculpt mode,
when mask painting is inactive.
There are some TODOs to work on during bcon3:
* Support tiled and stencil mode in 2D painting. Support alpha textures also.
* Tidy up overlay code. There's some confusion there due
to the way we use the primary brush texture sometimes for alpha, other times
for colour control.
WIP design docs will be in
http://wiki.blender.org/index.php/User:Psy-Fi/New_Brush_Tool_Design
- pass string size to BLI_timestr() to avoid possible buffer overrun.
- quiet warning for mingw.
- include guards for windows utf conversion funcs.
- fix for mistage in edge-angle-selection check.
- some style cleanup.
Couple of precision issues here:
- Interpolation was rounding trunkcating colors, and because
of some precision issues value 254.999 became 254 leading
to troubles later.
Now color interpolaiton will do rounding to nearest int.
- Subtract was setting channels to something negative which
confused color management (especially negative alpha),
Now subtract effect will clamp channels to 0 from bottom
and also do some tricks to prevent small alpha which
could also confuse color management.
Issue was caused by delayed or missing image user frame
number update, which lead to image loading failure in
cases node is updating from image signal callback.
Solved in a way that file from image datablock is used
for sockets detection instead of loading image for
current frame.
