Forward enum declaration is a bad idea, especially for C++ which requires
enum specification to dteermine which data type to use to store it.
Alternative would be to not use enum as an arument and pass it as int,
but actually would rather be strict on typing -- using explicit enum
as parameter type helps understanding the code and prevents possible
mistakes when using the function.
Now all add/remove operators for rigid body objects and constraints
automatically add objects to the appropriate groups and create groups if they
don't exist yet.
This makes handling rigid bodies easier but doesn't take away functionality.
If users want to handle groups manually they just need to create them before
adding any objects.
The previous behaviour was confusing and was even considered to be a bug since
clicking on rigid body in the physics tab seemed to do nothing.
Constraints connect two rigid bodies.
Depending on which constraint is used different degrees of freedom
are limited, e.g. a hinge constraint only allows the objects to rotate
around a common axis.
Constraints are implemented as individual objects and bahave similar to
rigid bodies in terms of adding/removing/validating.
The position and orientation of the constraint object is the pivot point
of the constraint.
Constraints have their own group in the rigid body world.
To make connecting rigid bodies easier, there is a "Connect" operator that
creates an empty objects with a rigid body constraint connecting the selected
objects to active.
Currently the following constraints are implemented:
* Fixed
* Point
* Hinge
* Slider
* Piston
* Generic
Note: constraint limits aren't animatable yet).
Add operators to add/remove rigid body world and objects.
Add UI scripts.
The rigid body simulation works on scene level and overrides the
position/orientation of rigid bodies when active.
It does not deform meshes or generate data so there is no modifier.
Usage:
* Add rigid body world in the scene tab
* Create a group
* Add objects to the group
* Assign group to the rigid body world
* Play animation
For convenience the rigid body tools operators in the tools panel of the 3d view
will add a world, group and add objects to the group automatically so you only have
to press one button to add/remove rigid bodies to the simulation.

Things like brush size and strength accessors now take a scene
parameter rather than guessing about which Scene's unified paint
settings to use.
Setting the size/strength through RNA can now be done separately for
the brush or the UnifiedPaintSettings.
The UI python code required updating to check whether the
size/strength controls should use brush or UnifiedPaintSettings RNA.
Radial control also required some updates to switch between the two
RNA sources.
* Object velocity can now be used to determine brush influence and color.
* Brushes can now be set to "smudge" existing paint.
* Added new operators to easily add and remove surface output mesh data layers from Dynamic Paint ui.
* Fixed drip effect algorithm to work properly on forces pointing towards surface.
* Adjusted drip effect speed.
* Drip effect can now use canvas velocity and acceleration to influence drip direction.
* Fixed texture mapping for material enabled brushes.
* "Object Center" type brushes can now use "material color" as well.
* Improved surface partitioning grid generation algorithm.
* Fixed possible invalid brush collision detection when OpenMP enabled.
* Fixed incorrect random sized particle displace/wave influence.
* Fixed "Object Center" brush color ramp falloff.
* Fixed invalid zero alpha sampling when rendering vertex colors.
* Lots of smaller tweaking.
* Canvas and brush can be now enabled simultaneously. This way it's possible for two canvases to interact.
* Added basic anti-aliasing support for vertex surfaces.
* 3D-view color preview now works even when there's subsurf modifier after Dynamic Paint in modifier stack.
* Added a new brush option to use proximity from object center.
* Default surface frame range now use scene's start and end values.
* Improved ray checks for volume brushes.
* Added new "non-closed" option for volume brushes. This way it's possible to use planar meshes as "volume" brushes with predefined ray direction.
* New carrot branch splash image by CGEffex.
* Improved brush affection code.
* Lots of smaller improvements.
* Fixed: Weight paint didn't work with particles.
* Fixed: Point cache didn't work for non-wave surfaces anymore since last commit.
Committed changes from previous weeks, biggest changes are:
* Canvas can now have multiple "surfaces" that each can have specific format, type and settings.
* Renewed UI to support this new system.
* Aside from old "image sequence" output format, Dynamic Paint can now work on vertex level as well. Currently vertex paint and displace are supported.
* Integrated vertex level painting with Point Cache.
* Added viewport preview for Point Cache surfaces.
Due to massive amount of changes, old Dynamic Paint saves are no longer supported. Also some features are temporarily missing or may not work properly.
Patch to make the radial control more generic with RNA. Patch was
reviewed here: http://codereview.appspot.com/4280080/
Prior to this update, the radial control code in trunk had generic
parts of the radial control implemented as an incomplete operator
within WM. Then each different user of the radial control had to
implement a separate operator to actually pass in specific brush data
-- e.g. sculpt's brush size, vpaint's brush size, etc.
This patch removes all the extra operators and makes the WM operator
do everything. It now takes several RNA path strings as its properties
-- the only required property is data_path, which specifies the data
to be modified by the radial control. The other paths affect display
in various ways, e.g. rotation, color, etc.
In addition to decreasing some duplicate paint brush code, these
updates make it pretty easy to enable radial control for other
purposes (and it can be set up entirely though python or keymaps, no
extra C code needed.)
Only source/blender/editors/ dir, should not give errors on different platforms
Only removing: UI_*.h, ED_*.h, WM_*.h, DNA_*.h, IMB_*.h, RNA_*.h, PIL_*.h
- particle set weight operator (Shift + K) and from the menu.
- mirror vertex groups operator can also flip weight group names.
a number of utility functions for weight groups added
int *get_defgroup_flip_map(struct Object *ob);
void flip_vertexgroup_name (char *name_r, const char *name, int strip_number); // moved from modifier.c
void copy_defvert (struct MDeformVert *dvert_r, const struct MDeformVert *dvert);
void flip_defvert (struct MDeformVert *dvert, int *flip_map);
2. Add action parameter to Select_All_Toggle operators, rename to Select_All.
Options are Toggle (default), Select, Deselect, Invert (same as select swap). This makes it possible to map separate hotkeys for select all and deselect all.
NOTE for Aligorith: I didn't change animation operators for select_all which already had an Invert operator. These should be fixed eventually.
Keymaps are now saveable and configurable from the user preferences, note
that editing one item in a keymap means the whole keymap is now defined by
the user and will not be updated by Blender, an option for syncing might be
added later. The outliner interface is still there, but I will probably
remove it.
There's actually 3 levels now:
* Default builtin key configuration.
* Key configuration loaded from .py file, for configs like Blender 2.4x
or other 3D applications.
* Keymaps edited by the user and saved in .B.blend. These can be saved
to .py files as well to make creating distributable configurations
easier.
Also, user preferences sections were reorganized a bit, now there is:
Interface, Editing, Input, Files and System.
Implementation notes:
* wmKeyConfig was added which represents a key configuration containing
keymaps.
* wmKeymapItem was renamed to wmKeyMapItem for consistency with wmKeyMap.
* Modal maps are not wrapped yet.
* User preferences DNA file reading did not support newdataadr() yet,
added this now for reading keymaps.
* Key configuration related settings are now RNA wrapped.
* is_property_set and is_property_hidden python methods were added.
The goodies:
* Curves can be used as normal dynamic effectors too with
the new "curve" field shape.
* Group visualization has optional duplication counts for
each object in the specified group.
* Object & group visualizations, which are done without
taking the dupliobject's global position into account
(unless the whole group is used). This is much nicer than
the previous behavior, but I added a "Use Global Location"
option for those who want to use it the old way.
* The active particle system's particles are now drawn a
with theme coloured outline instead of pure white.
* Added object aligned velocity factors (buttons categorized
and re-organized too).
Bug fixes:
* Absorption didn't work as the ui toggle button was forgotten.
* Some other force field ui tweaks.
* Crash after adding children and changing trails count.
* Display types "cross" and "axis" crashed.
* Particles weren't drawn with correct coloring.
* Billboards didn't update properly in viewport to camera
location changes.
* Particle rotation wasn't recreated correctly from point cache.
* Changing particles amount crashed sometimes.
* Some files with child hair crashed on loading.
* Compiler warning fixes.
* Adding boids crashed on frame 1;
Editors Modules
* render/ module added in editors, moved the preview render code there and
also shading related operators.
* physics/ module made more consistent with other modules. renaming files,
making a single physics_ops.c for operators and keymaps. Also move all
particle related operators here now.
* space_buttons/ now should have only operators relevant to the buttons
specificially.
Updates & Notifiers
* Material/Texture/World/Lamp can now be passed to DAG_id_flush_update,
which will go back to a callback in editors. Eventually these should
be in the depsgraph itself, but for now this gives a unified call for
doing updates.
* GLSL materials are now refreshed on changes. There's still various
cases missing,
* Preview icons now hook into this system, solving various update cases
that were missed before.
* Also fixes issue in my last commit, where some preview would not render,
problem is avoided in the new system.
Icon Rendering
* On systems with support for non-power of two textures, an OpenGL texture
is now used instead of glDrawPixels. This avoids problems with icons get
clipped on region borders. On my Linux desktop, this gives an 1.1x speedup,
and on my Mac laptop a 2.3x speedup overall in redrawing the full window,
with the default setup. The glDrawPixels implementation on Mac seems to
have a lot of overhread.
* Preview icons are now drawn using proper premul alpha, and never faded so
you can see them clearly.
* Also tried to fix issue with texture node preview rendering, globals can't
be used with threads reliably.
