Finally, here is the basic (functional) prototype of the new animation system which will allow for the infamous "everything is animatable", and which also addresses several of the more serious shortcomings of the old system. Unfortunately, this will break old animation files (especially right now, as I haven't written the version patching code yet), however, this is for the future.
Highlights of the new system:
* Scrapped IPO-Curves/IPO/(Action+Constraint-Channels)/Action system, and replaced it with F-Curve/Action.
- F-Curves (animators from other packages will feel at home with this name) replace IPO-Curves.
- The 'new' Actions, act as the containers for F-Curves, so that they can be reused. They are therefore more akin to the old 'IPO' blocks, except they do not have the blocktype restriction, so you can store materials/texture/geometry F-Curves in the same Action as Object transforms, etc.
* F-Curves use RNA-paths for Data Access, hence allowing "every" (where sensible/editable that is) user-accessible setting from RNA to be animated.
* Drivers are no longer mixed with Animation Data, so rigs will not be that easily broken and several dependency problems can be eliminated. (NOTE: drivers haven't been hooked up yet, but the code is in place)
* F-Curve modifier system allows useful 'large-scale' manipulation of F-Curve values, including (I've only included implemented ones here): envelope deform (similar to lattices to allow broad-scale reshaping of curves), curve generator (polynomial or py-expression), cycles (replacing the old cyclic extrapolation modes, giving more control over this). (NOTE: currently this cannot be tested, as there's not access to them, but the code is all in place)
* NLA system with 'tracks' (i.e. layers), and multiple strips per track. (NOTE: NLA system is not yet functional, as it's only partially coded still)
There are more nice things that I will be preparing some nice docs for soon, but for now, check for more details:
http://lists.blender.org/pipermail/bf-taskforce25/2009-January/000260.html
So, what currently works:
* I've implemented two basic operators for the 3D-view only to Insert and Delete Keyframes. These are tempolary ones only that will be replaced in due course with 'proper' code.
* Object Loc/Rot/Scale can be keyframed. Also, the colour of the 'active' material (Note: this should really be for nth material instead, but that doesn't work yet in RNA) can also be keyframed into the same datablock.
* Standard animation refresh (i.e. animation resulting from NLA and Action evaluation) is now done completely separate from drivers before anything else is done after a frame change. Drivers are handled after this in a separate pass, as dictated by depsgraph flags, etc.
Notes:
* Drivers haven't been hooked up yet
* Only objects and data directly linked to objects can be animated.
* Depsgraph will need further tweaks. Currently, I've only made sure that it will update some things in the most basic cases (i.e. frame change).
* Animation Editors are currently broken (in terms of editing stuff). This will be my next target (priority to get Dopesheet working first, then F-Curve editor - i.e. old IPO Editor)
* I've had to put in large chunks of XXX sandboxing for old animation system code all around the place. This will be cleaned up in due course, as some places need special review.
In particular, the particles and sequencer code have far too many manual calls to calculate + flush animation info, which is really bad (this is a 'please explain yourselves' call to Physics coders!).
*******
- Ported ObData to center, center new and centur cursor
- its currently 1 operator
- no warning or error popups until its figured out how best to do so
- possibly full of ugly code and things done worng way, had a hard time trying to understand this code
- some more house cleaning and removal of unused functions
*******
- Ported show/hide objects as the clear/set restrictview operators (request of kaito)
- clear is not using a context loop as there is none currently available
- set uses a popup menu for hide select and hide unselected
hotkeys are H and Alt-H (set, clear)
- ported the undo calles, to use ED_undo_push where available
********
- added clear location/rotation/scale/origin
- each action is a seperate operator
- Drawing is delayed as the tag_region_redraw does not seem to have an effect perhaps a transformation notifier is needed
- for the view to update just do some transformation, like press G
- changed the shortcut key for area rip to alt-ctrl-r so it dosn't conflict with clear rotation
- Edit mode Mesh undo/redo back
(undo for editmodes needed recode, todo for curve/lattice/etc)
- Added border select for edit mesh
- Added Akey (de)select all for edit mesh
- Added notifiers for mode changes.
This is also the first trial to dynamically add/remove
keymap handlers, based on modes. For that reason the Object
keymap was split in 2, modal and non-modal. On TABkey, the
view3d listener removes and adds maps.
The view3d keymap still handles generic mouse/border selection.
Internally it will verify modes.
The modes are not re-implemented still... have to move this
to scene context.
So, editmode mesh is back! :)
At the moment only TABkey works and mouse select, 1 vertex at a
time. More will follow of course.
Note for the devs:
- G.editMesh has been removed, be careful with old code.
- EditMesh now is property of Mesh itself
Although it means unlimited editmodes, for migration purposes we
better stick to 1 "obedit" per scene, which is in Context too
- G.obedit will get removed soon, so use CTX_data_edit_object(C)
Or if you can't, just scene->obedit for now
- Also removed the CTX_data_edit_mesh(), this has no meaning
anymore. EditMesh is not context senstitive anymore, only the
edit-object for time being is.
- Martin: I've already tucked some EditMesh pointer in T and
removed all G.editMesh there.
******
- ported Make track , and Clear track (ctrl-t, Alt-t)
- make track is a direct port does not use context data loops
- make Track crashes as Constraints have not been ported yet
- added select_extend to mouse select so now you can use shift again
- Still does not use Context data loops as this get all messed up, kaito can you look into it
- currently only works with 1 modifier key at a time so ctrl+alt does not work, until i can figure out how best to achieve this
*******
Small commit, moved selection Operators to Object editor (object_edit.c) as per kaito's request
- normal selection and border/circle select are still in view3d as they depend too much on view3d
Further simplifying making operators with menus;
now you can add an 'invoke' callback:
WM_menu_invoke
which will automatically generate a menu with choices and assign
it to the property 'type'.
What also helps typing is the new RNA_enum_is_equal() function.
Here's a paste of the now committed 'clear parent'. Note the
undo push will become a flag too.
http://pasteall.org/3660
(Brecht; fixed small bug in RNA_enum_is_equal!)
To evaluate: solving dependencies for multipe scenes... probably
will make a more generic flush call.
Object: converted the old horrible editobject.c, now as file:
editors/object/object_edit.c
Still lots of WIP, I've operatorified "Make Parent". Check here
the new API at work: http://pasteall.org/3650/c
IMPORTANT NOTE FOR BRECHT:
game property defines were clashing with RNA, i've renamed game
defines for now.
