===========================
- Do not show frame boundary border when stabilization isn't enabled.
- Separate stabilization settings from display in clip editor.
Now clip can contain stabilization data but still be displayed
un-stabilized in clip editor.
- Internal changes in stabilization:
* Use separated location/scale parameters rather than 4x4 matrix.
In some ares "decomposed" data is needed (text draw functions, i.e.).
Also such decomposed data could be used in compositor.
* MovieClip now uses own structure for cache where additional data
can be stored. MovieCache structure now one of properties in
this new structure.
* Get rid of stable image buffer stored in MovieClipStabilization
structure. Pre-created buffer for scaling still stored there.
This helps to keep playback realtime -- re-creating this buffer
introduces ~15% slowdown.
- Added sliders to 2D stabilization panel which controls intensity
of translation/scale which applies on shot.
- Added filter type to Stabilize2D compositor node. Supports nearest,
bilinear and bicubic interpolation.
- After discussion with Sebastian and Francois added new node called
Transformation. It can apply translation, rotation and scale. It's
not the same thing as applying this components separately -- all
transformation is happening inside "canvas". And it should be more
accurate on interpolation and sub-pixel translation.
Need to check order of applying translation/scale/rotation btw.
- Added output sockets to movie clip compositor node. They holds
stabilization data which can be used by Translate or Transform
nodes.
- Minor fix of UI issues in Display panel.
===========================
Changed behavior of 2D stabilization:
- Fixed epic spelling error.
- Neither 3d viewport nor MovieClip compositor input node
are using stable footage now.
- Now one thread lock can be avoided -- stable shot
isn't acquiring from several threads.
- Added compositor noe Distort->Stabilize 2D which is
supposed to stabilize "incoming" image using movie clip
block as reference.
Probably it could be useful to define MAT4 socket type and
use it in MovieClip node as output for stabilization and
as input socket for Stabilization node so relation could be
easily visible on "graph".
===========================
Implemented 2D stabilization:
- Based on average point of several tracks.
- Tracks for stabilization are controllable from
"2D stabilization" panel.
- Implemented autoscaling. Could fail if average point is
too close to frame boundary.
- Background clip in 3D viewport and MovieClip input
compositor nodes are using stable shot.
Some internal weak things:
- Stable shots aren't cached in moviecache. There is
only one "slot" for stable shot inside stabilization
structure.
- This could fail if several threads are requested different
frames (for example when starting playback, pause to make
Nodes Editor trigger refresh, continue playback).
- Due to it shouldn't crash i decided to implement better
caching for stable shots a bit later.
Issue was that the Shader tree execution changed the ShaderInput.
Changes are that the UI is updated that only the main material will have the pass_index this is displayed in the "render pipeline options" panel.
When the material is not a node material the pass_index will be shown at the "options" panel
To test enable nodes on the material
Add a new input material
change the pass_index of the material (render pipeline options)
Enable RenderPass material ID and use the compositor to read out the material pass

when using the node on a single white pixel on black background, the output should look like as the bokeh image.
being a round image, but it looked like a donut.
the make_gausstab used dist/rad and bokeh used (dist/rad)*2 - 1
I changed it to reflect the correct bokeh circular image
this will reconnect nodes as if the deleted node is muted.
Operation is added to the space_node node menu and to the keymap as CTRL-X
to test this just add some nodes to the space_node
select one or multiple nodes and press CTRL-X
It should reconnect the nodes as they were muted
limitations:
1. it performs a delete and reconnect per node. It does not evaluate all selected nodes as one whole
2. mute only supports Value, Vector and Color data types, so does this feature
3. not usable for nodes where input and output does not match (like colorToBW)
Where reconnect could not be preformed the links will be removed from the model.
Undo works with this delete with reconnect.
A mesh can consist out of multiple material. Take a character with clothing's. the skin can be a different material as the different clothing's. During compositing it is a common use-case to only do a part of the composit on only a specific material. Currently this can not be done.
In blender movies this feature is known to be implemented, but until now it never got integrated into trunk.
Proposal
With material index the Blender internal renderer will be capable of creating a buffer containing the material indexes of the first pixel-hit. This will be implemented in the same manner as the object index.
In the compositor the ID Mask node can be used to extract the information out of the Render pass.
Impact
User interface
On the properties-space the next changes will be done
Scene⇒Render layer⇒Passes⇒Material index will be added
Material⇒Options⇒Pass index will be added
DNA
Material struct will get an new field called “index”. this will be a short-type.
Material struct the field pad will be removed.
A new Render-layer pass will be added (bit 1«18)
RNA
Material RNA is updated (based on “pass index” from object)
Render layer RNA is updated (based on IndexOB)
Blender internal renderer
The Blender internal renderer will process the render pass as a copy of the Object index.
Blender compositor
The render layer input will get a new output socket called “IndexMA”
Usage
An example on how to use material index can be found at:
https://svn.blender.org/svnroot/bf-blender/trunk/lib/tests/compositing/composite_materialindex.blend
This is also example of a commit message longer than the commit itself :)
- comment/remove assignments from values to themselves.
- add case break statements (no functional change but some source code checkers notice).
- fix python errors when the sculpt brush is None.
blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.
- remove some warnings
- fix typos
- cmake allow in-source build (when WITH_IN_SOURCE_BUILD is defined)
- cmake, use an explicit list of rna files (don't glob)
Compositing, lens distortion node: it delivered RGBA out with alpha zero,
making it not draw previews, violates both premul or straight alpha usage.
Now it just sets alpha to 1 for entire output.
Cleaned code readability a bit as well.
Clamped the maximum displacement distance to 4 x the input image dimensions - prevents hanging when vary large values are mistakenly plugged in, such as Z buffers,
- Colormanagement code was gamma correcting non-RGBA buffers in composite.
(Like vector buffers).
- Crash on using "use Color Management" button during composites, because
it was freeing all node images. Added code to stop first jobs before
freeing. It sends notifier for recomposites after free anyway.
Compositor/texture nodes: math node now allows to use pow() for
negative raising too, but only when that value is near-integer.
For other negative cases result is zero.
