* Removing duplicate api functions
* Shuffled around newly added api functions to make the ordering more consistent
* Fixes for a few bugs in the api functions as I checked over them
* Replaced most of the #defines for flags and modes with enums
- renamed .add() to .new() for rna collection functions since they dont add an existing item.
- remove 'name' as an argument from the new driver target function, better to keep the api minimal and let scripters use the data api for editing values after.
- added some api functions to keep rna api from becoming a mess.
eg.
scene.objects.link()
object.constraints.new()
mesh.verts.transform(...)
mesh.faces.active
PropertyRNA stores an StructRNA pointer where these can be defined.
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions
in new code:
http://www.pasteall.org/9052/python
* Removed the hack-functions to set euler rotations from the values set in the other rotation representations, even when euler rotations weren't being used. I pressume that this was added for being able to represent quats in terms of eulers for the UI, but really it would break animation evaluation (i.e. euler curves after quaternion curves would always block the quaternion curves).
* Object rotation values in the transform properties panel now take into account rotation modes, so the appropriate rotations will get converted to quaternions before being drawn.
* Fixed a few bugs with some of the conversion code (minor stuff left out).
Animating rotations using different rotation modes should now work more often than before.
Previously, quaternion and axis-angle values were stored in the same variable in DNA, but that was causing problems with other animation curves overwriting the values and causing the rotations to not work as expected.
There are still some issues, but I'll track those down later tonight
This (biggish) commit generalises the rotation modes functionality added for Bones, allowing Objects to use the various Euler Rotation orders, Axis-Angle, and Quaternion rotation representations.
I've also cleaned up the nomenclature of the rotation-related settings so that the naming styles are more consistent with each other. Unfortunately, this will break all files involving object or bone rotation animation made in 2.5 versions (2.4x will still get correctly converted).
General Notes:
* By default, Objects still default to using Eulers, while Bones will use Quaternions by default still.
* I've fixed all areas that I'm currently aware of to work with these changes. However, there are probably a few places where I've missed a few changes (i.e. auto-keyframing will need attention later).
* Removed the old "IPO-Keys" stuff from Transform code. I'm unlikely to restore this in the near future, and trying to fix that to include support for this commit would have been too much work.
* copied I/O scripts
* copied, modified rna_*_api.c and rna_*.c
I/O scripts not working yet due to slight BPY differences and RNA changes. Will fix them later.
Not merged changes:
* C unit testing integration, because it is clumsy
* scons cross-compiling, can be merged easily later
Note sure what to do with this one, and personally think
we should avoid using macros for this kind of thing:
V_GROW(edges);
source/blender/editors/mesh/loopcut.c:232: warning: value computed is not used
* PROP_NEVER_NULL is now a flag instead of a subtype.
* It works for function parameters too now, so setting
this flag can help avoid NULL checks in the function.
* Renamed LocalLamp to PointLamp, making it consistent
with the UI name.
* Set icons for the different lamp struct types.
* Added Transform Locks panel. The layout for rotation I'm not satisfied with yet, though it is the best alternative so far.
* Rotations can now be locked per-component for quats/axis-angle instead of going through eulers. This is currently enabled by the checkbox for the 'label' of the Lock Rotation column.
- The naming of the property in RNA + the way this is presented in the UI can get some work done.
- The setting for the 'w' component for quats/axis-angle is currently a separate flag in RNA, since I can't figure out how to lump this in under the 'lock_rotation' property instead (i.e. getting that to be either 3 or 4 components, depending on whether per-component locking is enabled).
- Editing values directly should not be possible when these locks are set...
* Fixed some tools which made use of this
* Added a few new methods for axis-angle conversions, and used these instead of manually performing those steps elsewhere
* Axis-angles to other representations now get their axes normalised to make sure that odd scaling doesn't occur.
* Made a few more tools work with axis-angles properly
The support for this is really quite hacky, and I might disable this later if we cannot get some parts to work nicely.
Some notes:
* This is currently stored in the same variable that quaternions are stored in, since they both have 4 components. However, in RNA, I've added 2 properties specially for this.
* There are some shearing issues using certain axes - i.e. (1,1,0) - that will need to be checked on.
* Transform code is really quite temporary for this. Just a quick demo of what can be done...
* Added missing prototype from arithb
* Added define for Axis-Angle rotations. This has not yet been hooked up for actual usage yet, since there are some issues regarding evaluation which I'd like to investigate further first.
* Editing numbuttons for posechannel transforms now updates in realtime. Sending ND_POSE|ND_TRANSFORM was causing confusion for the listeners (which only check for either/or)
* Partial fix for axis drawing on bones. Now the axes are drawn at the tips of the bones again, but unfortunately the texts aren't (since they only use the object matrix, they get drawn at the origin).
* Copy Rotation constraint should now work ok with this new code again. Previously, it was the only thing that really went beserk when the typos were still uncaught.
* Fixed one other case of a potential case where typos would cause problems.
* Made changing the rotation order setting perform conversions of the current rotation to an equivalent representation in the other orders/forms. This is done at RNA level, so maybe not that great for switching representations while animating?
Notifiers
---------
Various fixes for wrong use of notifiers, and some new notifiers
to make things a bit more clear and consistent, with two notable
changes:
* Geometry changes are now done with NC_GEOM, rather than
NC_OBJECT|ND_GEOM_, so an object does need to be available.
* Space data now use NC_SPACE|ND_SPACE_*, instead of data
notifiers or even NC_WINDOW in some cases. Note that NC_SPACE
should only be used for notifying about changes in space data,
we don't want to go back to allqueue(REDRAW..).
Depsgraph
---------
The dependency graph now has a different flush call:
DAG_object_flush_update(scene, ob, flag)
is replaced by:
DAG_id_flush_update(id, flag)
It still works basically the same, one difference is that it now
also accepts object data (e.g. Mesh), again to avoid requiring an
Object to be available. Other ID types will simply do nothing at
the moment.
Docs
----
I made some guidelines for how/when to do which kinds of updates
and notifiers. I can't specify totally exact how to make these
decisions, but these are basically the guidelines I use. So, new
and updated docs are here:

This commit is the start of an implementation of (euler) rotation orders for Bones (later to be extended to Objects too).
Technical details and references can be found at:
http://wiki.blender.org/index.php/User:Aligorith/EulerRotationOrder
In short, I've added a new set of Euler conversion functions (EulO... and ...EulO), coexisting with the old functions for now, which can handle different rotation orders.
Changes have only been made to the basic evaluation code. However, the following places will still need modifications:
* Transform code - needs to be made to use functions which take rotation order into account instead of using XYZ only
* Rotation constraints - same story
* Other rotation editing tools for armatures also need a check up, since there might have been some missing code when I ported eulers earlier
* Reviewed subtypes, making them more specific and adding new ones.
* Subtypes now have an associated type of units (length, area, volume,
mass, rotation, time, velocity, acceleration). These are not used
yet anywhere.
* Centralized code that decides the name of array items based on
subtype (XYZ, RGB), was copied in 3 places.
* RNA_def_float etc functions still need to be update, will do this
later together with another change.
* "Pushing down" the action to make a new strip will now make the new strip the 'active' one.
* 'Active Action' field in Animation Data panel is now editable as long as we aren't in "tweakmode"
* Settings for Bones can now be animated properly from UI
* Settings for constraints on bones and objects can now be keyframed properly
* Added missing 'subtarget' property wrapping for StretchTo constraint.
* Added a new UI Template for the 3-colour picker used to visualise + select the custom colours for a bone group.
* Finished wrapping the colour properties for Bone Groups in RNA. Although changing the colour-set used will change the displayed/cached colours, changing the colours via the colour wells will not change the colour set to 'custom' (as per 2.4x) yet. This needs a nice solution...
* Fixed context-related bugs with the Assign/Remove operators for bone groups. These were using context-iterators for selected posechannels, but that was only defined/valid for the 3d view (but not for the buttons window), hence a failure in that case.
* Added Bone Groups UI to 'Armature' context buttons for now. Later, it may be more convenient to have these with bones instead?
* Added operators for the operations that can be performed on these groups. Moved the core adding/removing functions to blenkernel so that they can be used elsewhere in future if need be.
* Properly wrapped bone groups in RNA. Copied the way that Vertex Groups are wrapped, since they share some similarities. Setting colours for bone groups still needs more work though.
Experimenting with cross-compiling my branch with MinGW on Linux:
- tweaked config/linuxcross.py, source/blender/makesdna/intern/SConscript and tools/Blender.py
So far linking fails.
* Bone Transform panel now works, using appropriate EditBone or
PoseChannel properties.
* Bone name and parent are now editable.
* Some other tweaks to the UI layouts for Armature and Bone.
* Notifiers for armature/editbone properties.
- added (uncommented actually) PoseChannel.pose_matrix
- added Object.dag_update that calls DAG_object_flush_update. I'm not sure if it's needed, but FBX exporter uses it.
* Added icon to property and enum property items. The latter is
responsible for the large number of files changed.
* For RNA functions, added PROP_RNAPTR flag to ask for a PointerRNA
as argument instead of a C pointer, instead of doing it implicitly
with the AnyType type.
* Material: properly wrap diffuse/specular param variables, and
rename some things for consistency.
* MaterialTextureSlot: added "enabled" property (ma->septex).
* Image: make animated property editable.
* Image Editor: make some things editable, notifiers, respect state.
* Context: fix issue with screen not being set as ID.
* Added Constraints template and Add Constraint operator.
* Added toggle=True/False parameter to uiItemR, to get a
toggle button (actual button) rather than an "option"
button (checkbox)
* Added OPTION/OPTIONN button type, to distinguish with
TOG/TOGN.
RNA:
* Make all modifier pointers editable, including correct updates.
* Added notifiers and updates to constraints.
* Fix a stack corruption, pointed out by Andrea, and potentially
causing crashes.
* Any Struct can now have ID properties, by creating a callback
function to create/return an IDProperty.
* Wrapped PoseChannel ID properties.
* Note there is still no way to create ID Properties in 2.5, though
the callback to get/create the initial group is now exposed through
RNA_struct_idproperties.
* Allow pointers to be editable, did SpaceTextEditor.text as a test.
* Changed PROP_NOT_EDITABLE to PROP_EDITABLE, and added
RNA_def_property_clear_flag.
* Removed rna_dependency.c test code.
