This merge-commit brings in a number of new features and workflow/UI improvements for
working with Grease Pencil. While these were originally targetted at improving
the workflow for creating 3D storyboards in Blender using the Grease Pencil,
many of these changes should also prove useful in other workflows too.
The main highlights here are:
1) It is now possible to edit Grease Pencil strokes
- Use D Tab, or toggle the "Enable Editing" toggles in the Toolbar/Properties regions
to enter "Stroke Edit Mode". In this mode, many common editing tools will
operate on Grease Pencil stroke points instead.
- Tools implemented include Select, Select All/Border/Circle/Linked/More/Less,
Grab, Rotate, Scale, Bend, Shear, To Sphere, Mirror, Duplicate, Delete.
- Proportional Editing works when using the transform tools
2) Grease Pencil stroke settings can now be animated
NOTE: Currently drivers don't work, but if time allows, this may still be
added before the release.
3) Strokes can be drawn with "filled" interiors, using a separate set of
colour/opacity settings to the ones used for the lines themselves.
This makes use of OpenGL filled polys, which has the limitation of only
being able to fill convex shapes. Some artifacts may be visible on concave
shapes (e.g. pacman's mouth will be overdrawn)
4) "Volumetric Strokes" - An alternative drawing technique for stroke drawing
has been added which draws strokes as a series of screen-aligned discs.
While this was originally a partial experimental technique at getting better
quality 3D lines, the effects possible using this technique were interesting
enough to warrant making this a dedicated feature. Best results when partial
opacity and large stroke widths are used.
5) Improved Onion Skinning Support
- Different colours can be selected for the before/after ghosts. To do so,
enable the "colour wheel" toggle beside the Onion Skinning toggle, and set
the colours accordingly.
- Different numbers of ghosts can be shown before/after the current frame
6) Grease Pencil datablocks are now attached to the scene by default instead of
the active object.
- For a long time, the object-attachment has proved to be quite problematic
for users to keep track of. Now that this is done at scene level, it is
easier for most users to use.
- An exception for old files (and for any addons which may benefit from object
attachment instead), is that if the active object has a Grease Pencil datablock,
that will be used instead.
- It is not currently possible to choose object-attachment from the UI, but
it is simple to do this from the console instead, by doing:
context.active_object.grease_pencil = bpy.data.grease_pencil["blah"]
7) Various UI Cleanups
- The layers UI has been cleaned up to use a list instead of the nested-panels
design. Apart from saving space, this is also much nicer to look at now.
- The UI code is now all defined in Python. To support this, it has been necessary
to add some new context properties to make it easier to access these settings.
e.g. "gpencil_data" for the datablock
"active_gpencil_layer" and "active_gpencil_frame" for active data,
"editable_gpencil_strokes" for the strokes that can be edited
- The "stroke placement/alignment" settings (previously "Drawing Settings" at the
bottom of the Grease Pencil panel in the Properties Region) is now located in
the toolbar. These were more toolsettings than properties for how GPencil got drawn.
- "Use Sketching Sessions" has been renamed "Continuous Drawing", as per a
suggestion for an earlier discussion on developer.blender.org
- By default, the painting operator will wait for a mouse button to be pressed
before it starts creating the stroke. This is to make it easier to include
this operator in various toolbars/menus/etc. To get it immediately starting
(as when you hold down DKEy to draw), set "wait_for_input" to False.
- GPencil Layers can be rearranged in the "Grease Pencil" mode of the Action Editor
- Toolbar panels have been added to all the other editors which support these.
8) Pie menus for quick-access to tools
A set of experimental pie menus has been included for quick access to many
tools and settings. It is not necessary to use these to get things done,
but they have been designed to help make certain common tasks easier.
- Ctrl-D = The main pie menu. Reveals tools in a context sensitive and
spatially stable manner.
- D Q = "Quick Settings" pie. This allows quick access to the active
layer's settings. Notably, colours, thickness, and turning
onion skinning on/off.
The Mesh Tools have quite few crucial tools that're missing from the toolbar. This is the main one.
The tools that're here should also be reorganized a bit to introduce actual orgnization, as it's quite sporadic at the moment. Will do that later.
Add simple uvs now does a cube unwrap and pack operation. Result is not
optimal by far but it should not result in crashes and it will be quite
usable for simple cases.
Do not generate materials/images/UVs if they are missing.
Now we spawn a panel ("Missing Data") with operators to generate the missing data and
pop a warning if user tries to paint without them.
The reason we have reverted this is that it is too easy to end up with more textures
than we wanted. It was impossible to enter texture paint without having textures added,
and code makes too many assumptions about what user may want.
Discussed during Sunday's meeting.
This might be a candidate for 2.72a but I'm not sure how other artists will take this
(and how refined and crash-free it is), better make a few iterations first.
And for interested parties...test please, don't wait until after a release to poke with such issues.
Also, add slot operator now adds a new unconnected image node in cycles. Only
used in the "Missing Data" panel. This should be a separate commit but I am squashing it into the same commit because
it relies too much on changes done here and can be reverted easily if complainstorm occurs again.
Include explicit control for texturing:
This commit introduces a painting mode option, available in
the slots panel. The default value "Material" will create slots from the
blender material, same as just merged from the paint branch.
The new option "Image", will use an explicit image field that artists can use
to select the image to paint on. This will should allow painting regardless
of the renderer used or for use in modifiers.
Remotely based on patch by kevindietrich (Kévin Dietrich), but using
a single generic panel here, as suggested by UI team.
Note we add this panel in all modes (only one tweak in scuplt mode,
where there is no history menu generated it seems, unlike other
'paint-like' modes), we can decide to move it into its own tab later.

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.
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.
Most weight tools also work in edit mode.
This change exposes all applicable tools
within a separate weight tool panel
in the tools tab of the tool shelf

- autodetect optimal default, which typically avoids HT threads
- can store setting in .blend per scene
- this does not touch general omp max threads, due i found other areas where the calculations are fitting for huge corecount
- Intel notes, some of the older generation processors with HyperThreading would not provide significant performance boost for FPU intensive applications. On those systems you might want to set OMP_NUM_THREADS = total number of cores (not total number of hardware theads).
do not use different stroke property names for different paint systems.
This was done due to different stroke sets being supported for each
system, but this lead to trouble if we changed the names (due to
different stroke sets being supported) and users created custom keymaps
with the old property name saved.
The first part of this fix addresses master. A similar commit will be
done to soc-2013-paint.
Located on topology panel.
To use just click on button and click on mesh.
Operator will just use the dimensions of the triangles below to set the
constant detail setting.
Also changed pair of scale/detail size with nice separate float
percentage value.
Nothing spectacular here, fill tools are easy. Just take the dyntopo
code and repeat until nothing more to do.
The tool can be located in the dyntopo panel when the dyntopo constant
detail is on.
Also added scale factor for constant detail. This may change when detail
sampling gets in, I am not very happy with having two numbers here,
still it will give some more control for now.
Dyntopo detail in object space. This allows to set the detail in
percentage of blender units and sculpt in this detail constantly,
regardless of the distance to the mesh.
This commit just enables the functionality, which is really trivial.
There will be some more commits like detail flood fill and
detail sampling in the future.
