* Added separate menu items for Link and Append.
* Change some OPERATOR_FINISHED to OPERATOR_CANCELLED.
* Remove some IPO specific hacks, these are no longer ID blocks,
so not necessary to take into account.
* Some comment and code formatting tweaks.
* Move function to compute visible screen layers to BKE.
* Use this now in the depsgraph, was still using this all layers
to flush. Still missing a way to get the current scene in
background mode..
* Also two more function to not require a scene pointer anymore:
* DAG_object_update_flags is now DAG_id_update_flags.
* DAG_ids_flush_update is now available next to DAG_scene_flush_update.
* Totally new try to get cache running
* Didn't try "bake" and such things yet
Hint
* Very verbose yet
* Please do only test new blend files, not old ones!
Please give me feedback on my blog about the old crashers.
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.
- rename "Nurb" to "Spline" in RNA, eg. bpy.data.curves[0].splines[2].type == 'NURBS'
from a user perspective spline is a more generic term while Nurb is misleading when used for beziers and poly lines.
- added curve.active_spline property so the python UI can display the last selected curve.
- set the active spline when entering editmode (uses first selected spline)
- added back Hide Handles as a curve property (removed the global flag), access from the view panel in editmode.
- added hide normal option for curve, normal size access for curve and mesh display.
- changing orderU/V, endpoints, cyclic, bezierU/V now work in editmode and calls update functions.
- entering editmode was crashing with text objects
- curve.switch_direction() crashed (own fault from last commit)
- Tkey for tilt was overridden by Toolbar, made Tilt Ctrl+T.
- OBJECT_OT_mode_set check for compatible modes before running - so curves dont try go into paint mode with V key for eg.
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.
