This mode simplify the stroke doing a resampling of the points and generate new geometry at the distance defined.
Sample function developed by @NicksBest
New Resample Stroke operator
This operator recreates the stroke geometry with a predefined length between points.
The operator uses the same code used in Simplify modifier.
Reviewers: @mendio
Merge points when the distance is less than a predefined value.
The method to interpolate the position created a wrong merge. Now, always the secondary point is merged with the first one (merge at first), except the last point.
- Move connected & projected into individual toggles.
- Top-level proportional editing button now only toggles.
- Use popover for proportional edit-mode falloff and options.
Note that it's no longer possible to toggle connected via key bindings,
although this could be supported again if it's needed.
Resolves T58081
Keymap: E - Extrude Gizmo supported.
If the extrude points are the first or last of the stroke, the stroke is extended.
If the extrude points are in the middle of the stroke, a new stroke is created because the grease pencil strokes can be only with 2 extremes and fold the stroke to get a new point gets very bad results.
Still pending define a new icon. Also, it could be good to set by default XYZ axis in the gizmo.
Note: There is a change in the transform_gizmo_extrude_3d.c gizmo for OB_MODE_EDIT_GPENCIL. This change must be undo when the mode will be integrated into OB_MODE_EDIT, but while we have both modes, we need to keep this code in order to keep running the gizmo.
New edit mode operator and post-processing brush option.
Trim works on a single GP stroke. It removes trailing points before and after the first intersection (or loop) nearest to the start of the stroke.
BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
This commit groups a set of new tools that were tested in grease pencil object branch before moving to master. We decide to do all the development in a separated branch because it could break master during days or weeks before the new tools were ready to deploy.
The commit includes:
- New Cutter tool to trim strokes and help cleaning up drawings.
- New set of constraints and guides to draw different types of shapes. All the credits for this development goes to Charlie Jolly (@charlie), thanks for your help!
- Segment selection mode to select strokes between intersections.
- New operator to change strokes cap mode.
- New option to display only keyframed frames. This option is very important when fill strokes with color.
- Multiple small fixes and tweaks.
Thanks to @pepeland and @mendio for their ideas, tests, reviews and support.
Note: Still pending the final icons for Cutter in Toolbar and Segment Selection in Topbar. @billreynish could help us here?
This operator allows to create a new stroke joining several selected points of different strokes.
The new stroke will use the current material.
To use, first select the points to be merged. Optionally can remove the old points and strokes.
The operator is available in Edit mode in the Specials menu and Stroke menu.
- Replace BKE_brush_getactive_gpencil -> BKE_paint_brush
(no need for per-paint-type brush access).
- Rename TOT_GP_EDITBRUSH_TYPES -> GP_EDITBRUSH_TYPE_MAX
(avoid sharing prefix w/ unrelated constants).
- Rename instances of `GP_EditBrush_Data` to 'gp_brush'
(`Brush` is typically called 'brush').
This should be purely an implementation change,
for end users there should be no functional difference.
The entire key configuration is in one file with ~5000 lines of code.
Mostly avoiding code duplication and preserve comments and utility
functions from the C code.
It's a bit long but for searching and editing it's also convenient to
have it all in one file.
Notes:
- Actual keymap is shared by blender / blender_legacy
and stored in `keymap_data/blender_default.py`
This only generates JSON-like data to be passed into
`keyconfig_import_from_data`, allowing other presets to load and
manipulate the default keymap.
- Each preset defines 'keyconfig_data'
which can be shared between presets.
- Some of the utility functions for generating keymap items still
need to be ported over to Python.
- Some keymap items can be made into loops (marked as TODO).
See: D3907
The toolbar now shows brush types, the brush selector now
only shows brushes matching the current tool type.
Details:
- Add's Paint.tool_slots (used by the toolbar).
- Removed custom grease pencil brush tool code.
- Bumped subversion.
See T57526 for details.
The pie menus were a legacy of old grease pencil and now need a full redesign or maybe a new add-on.
While we decide the way to go, the pie menus are disabled.
This commit adds a new armature modifier for grease pencil. The deformations are done reusing the mesh deform routines.
There is also a new operator in weight paint mode to help the artist to generate weights base on armatures. This operator is required because 2D animation workflow is not equal to meshes when parent an object to armatures.
In the drawing engine has been added the option to handle the Fade object parameter used in armatures to see the strokes while move the bones.
When rename bones, all related data of grease pencil is renamed too. This not only affect new armature code, but also layers parented and hook modifiers.
Thanks @aligorith for his review and help.
The operator allows to copy a complete layer with all frames or only active frame to a new object.
Can be found in edit specials menu (W key) or in Layers specials menu (last button near layer list).
This operator clean any stroke below a defined number of points. This is used because sometimes when use eraser some points keep missing.
Also some changes in the UI menu.
Add tool options to control how select operates (add/sub/set/and/xor).
Note: edit mode armature select still needs to support all options,
this is complicated by how it handles partial end-point selection.
This commit merge the full development done in greasepencil-object branch and include mainly the following features.
- New grease pencil object.
- New drawing engine.
- New grease pencil modes Draw/Sculpt/Edit and Weight Paint.
- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).
- Split of annotations (old grease pencil) and new grease pencil object.
- UI adapted to blender 2.8.

This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible.
Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.
