Improved error messages presented when trying to paste keyframes.
Previously, "No keyframes to paste" would always be displayed, even if
the copy/paste buffer had some contents but couldn't be pasted if
there weren't any F-Curves selected to paste to.

There won't be dangling "empty" actions left behind anymore in the
DopeSheet channel list after you've deleted all their keyframes (and
don't want to add keyframes to them anymore).
Of course, this poses problems with more actions getting created if
you then go and keyframe those objects again. If this does turn out to
be an equally bad problem, then another approach from the channel
filtering code side (probably aided by the restructed code) will help
(though doesn't solve the problem where people complain of having
heaps of "empty" actions dangling from objects they no longer want
animated).

type and data
Recoded Keyframe Smoothing operator to work better for continuous
curves (i.e. ones with monotonically increasing slopes in sections) as
opposed to hypothetically jagged ones.
The old method assumed that handles should be flat as otherwise, you'd
often get unsmooth curves just because you went and tilted some of the
handles for local extrema, causing some unkeyframed overshoots, which
also leads to changes in timing, which in turn often means unsmooth
motion. Hence, the code took advantage of this to do things with less
extra data.
However, now we have a proper "flatten handles" tool (under snap ->
horizontal) so this functionality is not needed in the general case
where it will lead to stair-stepping artifacts.

- Fixed problem where just trying to replace existing keyframes would
result in the intepolation set on that keyframe to get lost. This was
mostly an issue if trying to re-block some animation in the middle of
a shot, with the rest of the keys set to Bezier, but the first
keyframe in this new segment needing to be Constant so that we don't
get sloppy automatic interpolation in the way
- Hooked up Media-Play/Stop/Next/Prev controls to animation playback
and keyframe jumping functionality in default keymap in addition the
existing controls. I'm also considering whether to migrate Next/Prev
Keyframe key mappings off the Ctrl-PageUp/Down keys for a more
ergonomic option (i.e. shift <, shift >)

keyframe pasting code
|
|
|
|
|
|
- Offset, so you can paste at the same time of the original frames, at the current frame or relative to the current frame at time of copying.
- Merge method, so the pasted keys can overwrite keys in their range or the entire curve.
Currently there is no redo panel for these space types so the only way to access these options is with F6 redo popup.
|
|
- Pasting from 1 fcurve to any other fcurve now works (skip index and rna path checking).
- Pasting multiple fcurves between bones now works.
- If path checking fails, pasting matches indices so Scale XYZ can be pasted into Location XYZ for eg.
|
|
- removed deprecated bitmap arg from IMB_allocImBuf (plugins will need updating).
- mostly tagged UNUSED() since some of these functions look like they may need to have the arguments used later.

generic keyframe editing API, allowing more niceties...
|

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

* Made the dotted lines drawn for markers extend all the way to the top of the relevant views
* Shortened the default names for markers
|
|
* Added function for F-Curves to find the F-Curves in a given list which affect some named data, such as bones, nodes, or sequence strips.
* Added a BezTriple offsetting callback to be used with the F-Curve+Keyframe loopers in use for many of the keyframe editing tools.
|
|
This commit fixes #19908 and #20239. Deleting keyframes will now delete the F-Curves they came from too, if the F-Curves don't have any more keyframes and/or F-Modifiers providing any further motion info.
|
|
* 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:

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

* DopeSheet + Graph Editor - 'Sample Keyframes' option now tags newly created keyframes as being breakdowns. Also moved reduced the code duplication here by moving the core code for this to the animation module.
* Keyframing (Standard/Auto) - Added proper 'replace' option
Keyframes can now be rekeyed non-destructively when the INSERTKEY_REPLACE flag is provided to the keyframing API functions, since this option will make sure that only the values of the handles get altered.
For the Auto-Keyframing 'Replace/Edit Keys' option, this means that it truly works as it describes now, since it will now only replace the values of the keyframes on the current frame, and won't create new keyframes in the process or destroy the tangents already created for those keys.
For things like the sliders in animation editors, keyframes changing the value won't destroy existing tangents.

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.

I've gone through all the Animation Editor operators, making sure they send appropriate notifiers, and that these notifiers are handled.
* Added a separate category for animation-related notifiers, since the old-style ones attached to specific datatypes only was turning out to be not too feasible.
* For now, the focus has been on making sure that all Animation Editors update when there have been any potentially suitable changes at all. Later on, we can filter these more carefully to only take the ones we really need (for optimisation purposes)

As was discussed by the team the other day, copying keyframes (to copy/paste buffer) in DopeSheet/Graph Editor no longer relies on the selection status of the F-Curves, but rather on the selected keyframes only. This should be less confusing...
However, pasting keyframes still relies on having F-Curves selected to aid in the channel-matching process. There is still a lot of room for improvement in this area though (as noted in the code!).
|
|
The channel-matching code when pasting still needs improvements to work really nicely...
|
|
* Deleting keyframes should be safer now
* Graph Editor no longer crashes on F-Curves with no keyframes/samples
* Silenced console prints that occurred when an F-Curve had now keyframes.
|
|
* Copy/Paste still needs to be cleaned up to be functional. Auto-set preview range + View All also need some work to become functional...
* Smooth has been moved to Alt-O hotkey, as Shift-O was taken for Sample
* Renamed a few operators for DopeSheet to be more in line with Graph Editor ones, and to be less obscure.
* The 'join' and 'remove doubles' tools are not likely to be restored. I think that a few of the new tools cover this lack anyway. We can restore them if there is a real need.
* Record tool needs a rethink to be genuinely useful, so it's not included here anymore.
A note for anyone wanting to play with implementing this: store the sampled points using the new FPoint type in the FCurve instead of using BezTriples, as FPoints are used for storing sampled/baked data.
|
|
* Added back Auto Preview-Range tool (i.e. set preview-range from keyframe extents)
* Restored delete keyframe tool. For now, this doesn't delete empty F-Curves, even though its keyframe-api counterpart still does. I still need to figure out how to do this in the best way.
* Fixed crashes when selecting keyframes in 'object' summary channels
* Removed prototypes for a few unused/depreceated functions...

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!).

* Brought back clean (OKEY), sample (Shift-OKEY), and delete (XKEY/DELKEY) tools for the Action Editor.
Currently clean uses a predefined threshold (as a rna-prop, though it's still lacking the popup to set this when it is called)
* Added new file for 'destructive' keyframe operations/tools.
* Got keyframing.c compiling. Now, some of these tools need to be operatorised. Also, the API there might change when enough of the system is stable for RNA-IPO work to take place (so that it can be tested).
