This allows adding a "fake" sun beam effect, simulating crepuscular rays
from light being scattered in a medium like the atmosphere or deep water.
Such effects can be created also by renderers using volumetric lighting,
but the compositor feature is a lot cheaper and is independent from 3D
rendering. This makes it ideally suited for motion graphics.
The implementation uses am optimized accumulation method for gathering
color values along a line segment. The inner buffer loop uses fixed
offset increments to avoid unnecessary multiplications and avoids
variables by using compile-time specialization (see inline comments
for further details).
In addition to D319, this patch updates the parameter editor, the UI of Freestyle.
Using new API functionality and experience gained in making D319, this patch
provides a quite noticable speedup for commonly-used Freestyle linestyle modifiers.
As this patch touches a lot of code (and mainly the foundations) it is likely that
mistakes are made. The patch has been tested with a regression suite for Freestyle
(https://github.com/folkertdev/freestyle-regression-tests/tree/master), but testing
with scenes used in production is very much appreciated.

This patch creates an interface for selection mechanisms in opengl. This
makes it possible to switch between occlusion query based or select
rendermode based selection transparently.
This is really useful on graphics drivers that do not accelerate the
select rendermode path (some ATI cards are notorious for this, and the
new path is used by default there), since occlusion queries are always
hardware accelerated due to their use in games.
The option can be found under system - selection. Auto just enables
occlusion queries for ATI users while the rest of the options enforce
one of the two methods always.
There is just one known change, previous code enforced nearest bone to
always get selected, even when mouse selecting near the same position, I
couldn't replicate the behaviour though.
patch by me with edits and review by Campbell.
Thanks!
The issue is actually that creating a new image in texture paint mode
will set it always as a stencil image. Internally, the code checks if
the painted image is the same as the stencil and if it is, no painting
is done.
Solution is to expose a boolena to the operator for setting the image as
a stencil (could be an enum in th future for more uses)
Stencil UI is a bit weird here, will definitely redesign.
The button was intended to guide new users of Freestyle, but actually that is a matter
of documentation. The button is unlikely to be frequently used once users get familiar
with Freestyle panels in other contexts. Now that Freestyle has been part of Blender
since a while, it seems time to clean the UI.
Yep, at last it's here!
There are a few minor issues remaining but development can go on in
master after discussion at blender institute.

Thanks to Sergey and Campbell for the extensive review and to the
countless artists that have given their input and reported issues during
development.
Currently this gaussian blur implementation accumulates values in the
square kernel rather that doing X direction and then Y direction because
of the lack of using multiple-staged filters.
Once we can we'll implement a way to apply filter as multiple stages we
can optimize hell of a lot in here.
Another thing we can do is to use SSE2 instructions here.
Preset operators should avoid using `bpy.context.object.data` as a base
path to properties. This path is not available in the buttons context
when using pinned datablocks! Instead use the specific
`bpy.context.camera` and `bpy.context.lamp.sky` paths now, which lead to
the correct datablocks in any case.
Now the bevel tool, modifier, and internal operator have a material
slot # parameter that the user can set. If left at default of -1,
behavior is as current -- bevel face material is taken from the
closest original face (this may be ambiguous). If material slot
is >= 0, it gives the material slot index number for the material
to use.
This is related to Task T34861 to increase up & track axis options for TrackTo actuator. I've just added it to differential to facilitate an easier review.
With the patch applied you can select X, Y and Z axis for the Up axis, and X, Y, Z, -X, -Y and -Z for the track axis.
Related to the implementation I have used the algorithm from Trackto constrain placed in constrain.c but adapted to be used with MOTO library.
The wiki docs are here (http://wiki.blender.org/index.php/User:Lordloki/Doc:2.6/Manual/Game_Engine/Logic/Actuators/Edit_Object#Trackto_Actuator).

New properties 'line_color' and 'line_priority' are added to Material ID data blocks.
The 'line_color' property allows users to specify a per-material line color that can be
used as a Freestyle line color through Material color modifiers of line style settings.
The new line color property is intended to provide a solution for line color
stylization when a proper Freestyle support for Cycles is implemented (likely
as part of the upcoming Blender 2.72 release; see Patch D632). Materials in
Cycles are usually set up using shader nodes, and Freestyle won't be capable
of retrieving colors and other properties from node-based materials any soon.
The new line color property of materials addresses this foreseen limitation by
providing artists with an intuitive alternative mean to specify line colors on a
per-material basis independently from node trees.
The 'line_priority' property gives users a way to control line colors at material
boundaries. When a line is drawn along a feature edge at material boundaries,
one of the two materials on both sides of the edge has to be picked up to
determine the line color. So far there was no way to control this selection
(which was in effect at random). Now the material with a higher line color
priority will be selected.
The new per-material line settings are shown in the new Freestyle Line tab in
the Material context of the Properties window (only when Freestyle is enabled).
It is sometimes possible to end up with a lot of datablocks which have old + unused
"AnimData" containers still attached. This most commonly happens when doing motion
graphics work (i.e. when some linked-in objects may have previously been used to develop
a set of reusable assets), and is particularly distracting in the NLA Editor.
This commit adds an operator which removes AnimData blocks (restricted to only those
which are visible in the animation editor where it is run from) which are "empty"
(i.e. that is, have no active action, drivers, and nla tracks or strips).
This operator can be found from the "Edit" menu in the NLA Editor. Although it also
works when run from the DopeSheet or Graph Editors, it is of less use there since
those won't show these empty AnimData blocks by default (since by definition, such
AnimData blocks necesarily have no keyframes or drivers that can be shown), hence
there will be no feedback if the operator fails or succeeds.
Simply add an option to render settings to save an EXR cache,
just when the render is finished. Also changed RE_ReadRenderResult() to read
cache instead of temp sample files (those are fully volatile now anyway).
Path to save cached render results is an UserPreferences setting.
Also added 'Reload render' feature to the Image Editor (so one can now re-open a blend,
and in an Image Editor hit ctrl-R to (try to) reload last render from cache).

This revision is meant to update Freestyle's Python scripts to make full usage
of the new features of Python and Freestyle's Python API.
Freestyle's Python scripts are pretty old already, and were never given much
attention. With the 2.7x generation of Blender coming up, this is an excellent
time to update Freestyle's Python scripts, hopefully adding some new features
and achieving some speed improvements on the way.
Main goals:
* use for loops where possible
* general cleanup, making use of more recent python features (generators,
ternary operator, ect.)
* update the documentation on the way (it's lacking atm)

panels.
Patch by @Severin (with minor modifications by me). As discussed in
{D535} the node editor does not have real modal operator tools like the
3D view or image editors for instance, so it makes sense to utilise it
this way. Tabs really help in this area due to the large amount of node
types and categories. Further tweaks could be made later if the need
arises.
Exposes all supported unit systems & types, and to_value()/to_string() functions.
