Appending and Linking
* Linking Operator, invokes filebrowser for Append/Link
* Separated the append/link function into three parts:
** BLO_library_append_begin finds main for appending
** BLO_library_append_named_part appends one Object,Group, Material, ...
** BLO_library_append_end actually reads and expands the libraries
NOTE 1:
I also changed the returned properties for the filebrowser operators to the following convention:
"path" - the full path to a file or directory, means what is in directory + filename buttons in filebrowser
"directory" - the content of the directory button in filebrowser
"filename" - the content of the filename button in filebrowser
Usually only path should be required, but in some cases it might be more convenient to retrieve the parts separately.
Ton, Brecht: If you have time to take a look, let me know if anything needs to be fixed.
- use_radius option, off by default for 2.4x files, on by default on new curves.
- curve deform modifiers (think tentacles)
- follow path (parent mode and constraint)
- curve guides
- added back Alt+S to scale point radius
- Mat3Scale and Mat4Scale arithb.c functions to make a new uniform scale matrix.
- TODO, effectors, looks like they have no way to scale from the radius yet.
* 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
* added new twist method - "Tangent", suggested by Martin.
the nice thing about this is its stable no matter how you rotate the data, rotation is local to each segment.
* added smooth option that smooths the twisting (before applying user twist), to workaround Z-Up and Tangent's ugly curve twisting. Id prefer not to have this however it makes tangent much nicer. Possibly tangent can be improved some other way and this can be removed.
A smooth value of 1.0 will iterate over and smooth the twisting by the resolution value of the spline.
* Minimum-Twist method now corrects for cyclic twist by taking the roll difference between first and last, then increasingly counter rotate each segment over the entire curve. Previously it calculated from both directions and blended them.
details
* BevPoints use quats rather then 3x3 matrix.
* added BevPoint direction "dir" and tangent "tan" used only for 3D curves.
* don't calculate BevPoint->cosa, BevPoint->sina for 3D curves.
* split bevel tilt calculation into functions.
* nurbs curves currently don't generate tangents and wont work with tangent twist method.
* some of the use of quats should be optimized.
* smoothing is not animation safe, the higher the smoothing the higher the likelyhood of flipping.
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...
- Hair dynamics have their own panel in particle settings with the settings from cloth panel that apply to hair.
- Basic internal friction force to quickly emulate self collisions and volume preservation. (Still very early code, but gives some idea of what's possible).
- Softbody simulation is no longer used for hair.
* Old files with sb dynamics should just load the hair without dynamics so new dynamics can be applied.
* Invasion of particles exceptions in sb code is finally over.
- Collisions with other objects are disabled for now and will be worked out in the future.
Other changes/fixes:
- Particle mode editing flag wasn't saved properly.
- Some old files with edited hair didn't load correctly.
- Disabled delete & specials menu in particle mode for non-hair editing.
- Fixed yet one more cloth & softbody pointcache update issue.
- Disconnect/connect hair now uses only the deformed mesh so it works correctly also for subsurfed emitters.
- Hair editing now updates correctly with a moving emitter.
Added RGB space distance matte Node
Added HSV color matte Node
Fixed Image difference matte Node to use image differences instead of RGB space distance
Fixed luminance node for low end values being read wrong
Fixed CMP_util copy/swap functions not accounting for all channels
Fixed UI for difference matte Node
Added RNA for new nodes
Renamed BevPoint's members
* x,y,z -> vec[3]; compatible with other functions.
* f1 -> split_tag; used by displist to set the splitting flag.
* f2 -> dupe_tag; used in curve.c to remove duplicates.
BevList
* flag -> dupe_nr; was being used as a counter for duplicate points.
* use arithb.c functions where possible.
* arrays for coords, tilt and radius were being allocated, then copied into the BevPoint's, now write directly into the values without allocing/freeing arrays.
* Enable cache for high res + new preview
* Bugfix for smoke banding (in cooperation with N_T)
Hint: Work-in-progress regarding collision objects so can be broken, didn't test
Hint2: jahka enabled a general particle panel but
* bake button doesn't work
* step is not supported for cloth
* several other things there ;)
* Split object_edit.c into multiple files:
object_add.c, object_edit.c, object_hook.c, object_relations.c,
object_select.c, object_transform.c.
* Rename files to have consistent object_ and mball_ prefix:
object_shapekey.c, object_lattice.c, object_vgroup.c, mball_edit.c.
* Added operators:
* vertex group menu and set active
* apply location, rotation, scale, visual transform (location is new)
* make local
* make vertex parent
* move to layer
* convert to curve/mesh (not finished yet)
* Many small fixes for marked issues, but still much code to be cleaned
up here...
* Added a new option ('Fixed Position') for Follow Path constraint which allows you to constrain an object/bone to some fixed position along the curve. Unlike the default mode of operation, this doesn't depend on time unless you explicitly animate the offset percentage parameter associated with this.
* Made old (pre 2.5) files saved with armatures in pose mode load in pose mode again.
moved CU_2D to Nurb->flag in do_versions
This made simple type checks confusing to read.
many... if( (nu->type & 7)==CU_BEZIER)
replaced with ... if(nu->type == CU_BEZIER)
made setting rna curve_2d clamp the Z values. still more RNA/UI changes to do.
* 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?
- Moves hair from face-space to global space and back.
- Allows for editing of emitter mesh after hair combing.
- Disconnect hair before doing topology changing changes in mesh edit mode, connect after changes.
- Notes:
* The closest location on emitter surface to the hair root is used to connect the hair.
* Emitter deflection, sticky roots and add brush don't apply for disconnect hair in particle mode.
- Todo for future:
* Copy disconnected hair from object to another (when 2.5 has proper copy operators again).
* Possible automatic disconnect/connect with topology changing operations in mesh edit mode.
Other changes/fixes:
- Proper subtypes for some particle mode notifiers.
- Particle mode selections didn't draw correctly because of using lighting for the paths.

Access next to the "3D" edit button.
details...
- open curves use the first points orientation and minimize twist for each new segment.
- cyclic curves calculate the least twist in both directions and blend between them
- AxisAngleToQuat replaced inline code.
- Notice the model on the right now has more even corners. added Vec3ToTangent to arithb.c.
- Some big refresh issues with softbody & cloth point cache usage should now be fixed.
- Removed sticky objects from particles (better stuff will come back when I get to updating reactor particles).
- Some initial easy memory efficiency cleanup for ParticleData struct. The ultimate goal is to get particles less memory hungry -> more particles possible in single scene.
- Wrong path timing clamping caused hair particles to seem disappeared when changing between normal<->hair particles.
- "Calculate to current frame" in cache buttons baked instead of the intended function.
- Boids particle data is now a bit better organized.
Make local and make single user are back for ID template.
Internally these calls got unified, id_make_local and
id_copy are now used to do these operations for all types
that support it. Also reveals that for some ID types the
implementation is still missing.
Further, some small changes:
* unlink_text is now in blenkernel.
* copy_group was implemented.
* ID template now has an open operator again.
* fix preview to not change material reference count,
even if temporary it shows up with threaded preview.
* id_unlink unifies unlink for text, object and group.
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:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/NotifiersUpdateshttp://wiki.blender.org/index.php/BlenderDev/Blender2.5/DataNotifiers
* Added a 'rotOrder' parameter for constraint evaluation objects and constraint targets, which describes the rotation mode used for the matrices there.
Todos:
* Constraint targets default to using XYZ only for now. This will need be be addressed eventually.
* Copy Rotation constraint currently cannot use the new rotation order code for the target matrix. What's surprising is that even though it's just using XYZ as the old code did, it doesn't work, and yet everything else works nicely. Silly constraint! (it is almost impossible to improve this constraint further without breaking a rig out there)
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
* Convert operator - can currently be used to convert active Grease Pencil layer to curves. I had a look at making this part of a special "curve sketching" macro, though it seems that we cannot have modal operators coming first in a macro (and also cannot specify operator calling modes)
* Delete Active Frame operator - does what its name say it does. It deletes the active frame for the active layer of Grease Pencil sketches.
* Restored option to have strokes aligned to screen space. By default, this is not enabled (the setting for view-space is the default instead).
* Fixed bugs related to drawing/erasing in screen space.
- Baked point caches for particles, cloth and softbody can now be edited in particle mode.
* This overwrites the old cloth/sb cache editmode editing.
* The type of editable system is chosen from a menu.
* For particles the current particle system and it's current cache are used.
- Currently this only works for caches that are in memory, but some automatic conversion from disk to memory and back can be implemented later.
- All tools from hair editing can't be applied to point caches and are hidden in the tool panel and specials menu. Some functionality like subdividing paths can be later implemented in a slightly different way from how it works for hair.
- Code is not yet optimized for speed, so editing might be slow sometimes.
Known issues:
- Cloth doesn't update properly while in particle mode, due to the way cloth modifier currently works. Daniel can you check on this?
- As "particle mode" is not only for particles any more some other name would be in place?
- Better icons are needed for the path, point, and tip-modes as the current icons from mesh edit mode are quite misleading.
- Direct editing of point velocities is not yet implemented, but will be in the future.
Other changes:
- Hair editing doesn't require a "make editable" button press any more.
- Multiple caches in single particle system disables changing emission properties.
- Unified ui code for all point cache panels.
* Defined in buttons_particle.py and imported for cloth, smoke & softbody.
- Proper disabling of properties in ui after baking point caches. (Daniel could you please make needed disable code for smoke panels as their functionality is not familiar to me.)
- Hair weight brush has been removed. Once hair dynamics is re-implemented I'll code a more useable alternative to the functionality.
Bug fixes:
- Unlinking particle settings crashed.
- Deleting the active object with particles in the scene crashed.
- Softbody didn't write point caches correctly on save.
* Shuffled some code around, and renamed some functions used for getting context info
- Split UI-buttons into a separate file from stroke-drawing code
- Removed some obsolete code (i.e. old paint code that used to be in _edit, but which has been moved to _paint).
* Made drawing in 3D-View default to using the active object as the owner of the Grease Pencil data. For now, the drawing code will therefore only show the GP data for the active object only. More work to come on this.
* Fixed freeing code for Objects/Scenes with GP data.
Also, made the Outliner's horizontal scrollbar work better for keymaps view. It's still using an approximation of the width, but at least you can scroll now.
