It is now possible to create "scripted expression" drivers by simply
clicking on some property, and typing some short Python expression
prefixed with a '#'. This will result in a scripted expression driver,
with the typed-in text being created.
For example, you can click on X-Location of the default cube, and
type:
#sin(frame)
and a new driver will be created for the x-location of the cube. This
will use the current frame value, and modulate this with a sine wave.
Do note though, that the current frame is a special case here. In the
current implementation, a special "frame" driver variable, which
references the current scene frame is created automatically, so that
this simple and (assumed) common case will work straight out of the
box.
Future improvements:
- Explore possibilities of semi-automated extraction of variables from
such expressions, resulting in automated variable extraction. (Doing
away with variables completely is definitely 100% off the agenda
though)
- Look into some ways of defining some shorthands for referencing
local data (possibly related to variable extraction?)
* Removed frame-number display from NLA strips. Indeed doing so makes
things look cleaner/easier to identify.
* When transforming NLA strips, the "temp-metas" (purple strips) get
their frame extents drawn on either end, like in the sequencer, which
seems to be easier to read than the ones inside the strips.
---
The downside of this tweak is that there is no longer any visual
feedback for which strips run reversed instead of forwards, as that
used to be shown using the frame extents stuff.
Animation Editor toggle tweaks:
* By popular request, curve visibility toggles in the Graph Editor are
now represented using the eyeball icons
* Muting is now represented by a speaker icon (a speaker for this
purpose seems fairly common?)
New icons:
* Keying Sets now have their own icons (as found in a proposal on
jendrzych's "Pixel Sized" blog)
* Drivers also have their own icon now. This is just a hacky one I've
devised which doesn't look that great. Suggestions on this are very
welcome.
Channels can now be used as "animation containers" to be filtered
further to obtain a set of subsidiary channels (i.e. F-Curves
associated with some summary channel).
The main use of this is that object and scene summary channels can now
be defined without defining the filtering logic in three different
places - once for channel filtering, once for drawing keyframes in
action editor, and once for editing these keyframes.
An indirect consequence of this, is that the "Only selected channels"
option in Timeline will now result in only the keyframes for a
selected bones getting shown (when enabled), instead of all keyframes
for the active object. This was requested by Lee during Durian, and is
something which has only become possible as a result of this commit.
* F-Curves no longer show the name of the datablock of the property
they affect if this is an ID-block. For example, transform curves for
a cube won't get the "... (Cube)" suffix anymore. In these cases, it's
relatively clear that these belong to the parent datablock, so doing
this should be fine (and reduces clutter).
However, for non-id data (i.e. subsurf modifier settings) or bones,
this info still gets shown. In these cases, there is some ambiguity.
* "ActiveAct: <...>" is no longer shown for NLA action channels (i.e.
just the name of the action gets shown). This should make it easier to
see at a glance what action is being used.
* Removing the last of the owner/ownertype stuff. The bulk of this
stuff was removed in Part3 of the refactor, but it seems I forgot to
actually remove these struct members at the end of that.
* Texture datablocks without animdata aren't skipped immediately
anymore. This could lead to texture nodetrees on animdata-less
textures getting skipped.
This commit is aimed at cleaning up the filtering code by changing the
filtering idiom/pattern used. While the old code used a "check then
do" approach, the new code does a "grab then assimilate".
The main benefits are that:
* the code duplication that used to exist has now been removed, making
it easier to add new channel types for data
* a recursive "peeking" ability now means that the old problems with
data existing deep in the tree (i.e. figuring out whether a channel
should be shown based on whether it will have any descendents) should
now work much better than before.
In the process, I've found and fixed a few previously unnoticed bugs
with how some channels were constructed, so hopefully things work a
bit better now.
TODO's:
* Action-Group filtering stuff hasn't been refactored yet. This was
causing some grief in the past, so I still need to check this
carefully.
* Material Nodes support (missing in trunk) should be easy to slot in
now :)
* Insert Key on Selected Channels in Action Editor was broken
* Transform/Select All tools in Action Editor were broken as result of
filtering changes.
* Set Visibility operator, when used from Graph Editor now does
similar things to the TabKey lock/unlock operator with regards to the
flags it uses for filtering
the list of animated curves is closed
At long last, this old bludger can be put out to pasture. I figured it
would involve some of the visibility-filtering stuff I added, but this
required a bit extra effort than anticipated.
* This (big) commit is aimed at cleaning up the filtering flags used
by the animation channel filtering code. The list of filtering flags
has been growing a bit "organically" since it's humble origins for use
in the Action Editor some 3 years (IIRC) ago now during a weekend
hackathon. Obviously, some things have ended up tacked on, while
others have been the product of other flag options. Nevertheless, it
was time for a bit of a spring clean!
* Most notably, one area where the system outgrown its original design
for the Action Editor was in terms of the "visibility" filtering flag
it was using. While in the Action Editor the concept of what channels
to include was strictly dictated by whether the channel hierarchy
showed it, in the Graph Editor this is not always the case. In other
words, there was a difference between the data the channels
represented being visible and the channels for that data being visible
in the hierarchy.
Long story short: this lead to bug report [#27076] (and many like it),
where if you selected an F-Curve, then collapsed the Group it was in,
then even after selecting another F-Curve in another Group, the
original F-Curve's properties would still be shown in the Properties
Region. The good news is that this commit fixes this issue right away!
* More good news will follow, as I start checking on the flag usage of
other tools, but I'm committing this first so that we have a stable
reference (of code similar to the old buggy stuff) on which we can
fall back to later to find bugs (should they pop up).
Anyways, back to the trenches!
* Changed all int's to size_t's, where the int's were used for size of
channel list returned
* Object vs Base is now passed to filtering functions - was relic from
old owner/ownertype code which required access to bases
* Found bug in NLA code where filter was being overwritten and then
used again as input for some other function unintentionally
* Found bug where trying to select a NLA strip would crash if lamp
data was around
* Removed list-expanders for Materials, Textures, and Particles. So
instead of:
Object
Materials
Material 1
... material 1 anim data ...
we now have
Object
Material 1
... material 1 anim data ...
This makes it faster+easier to get to these items. If you don't want
to see all of these, you can still use the data-block filters from the
header to hide these.
* Internal cleanup - removed "owner" and "ownertype" settings from
bAnimListElem. The purpose of these was muddled, and more of a hassle
to maintain than doing anything useful - it was only really used for
the stuff above.
* Removed need for "sa->spacedata.first" casts all over the show for
animation editor tools which needed access to editor data. This can
now be retrieved directly.
I was going to include this change along with support for moving
FModifiers around on the stack, though that looks like it might be a
bit more involved than first though. To be dealt with later...
"entire array" property on by default, making it easier to add
transforms to Keying Sets.
This doesn't affect Keying Set paths added via Python or any other
means.
Following on from my commit to introduce frame ranges for FModifiers,
those frame ranges can now have blend in/out values. By setting a
blendin or blendout value, you're specifying the number of frames for
the modifier's "full influence" to take effect or fade out relative to
the start/end frames.
The "full influence" above needs a little clarification.
When the "use influence" setting is enabled, "full influence" is taken
from the "influence" slider (a new setting). Otherwise, it uses 1.0
(i.e. unmodified influence, same as old behaviour before the
introduction of influence controls). The influence slider basically
says how much the modifier's effects are allowed to contribute to the
final result.
---
Notes:
- This opt-in "Use Influence" approach is really forced upon us
because there are heaps of old files for which we cannot easily
version patch without spending some effort going through all the data
in the file, hunting out the F-Modifiers.
- interpf() seems to use a backwards order compared to everything else
Using this feature, it is now possible to for example have different
noise-profiles for different parts of a curve, which makes it possible
to do animate camera shake for example.
Or perhaps, for having greater control of mixing and matching
different parts of F-Modifier effects, such as combining several
generator modifiers to get multi-case functions for instance.
See http://aligorith.blogspot.com/2011/06/gsoc11-fmodifier-range-
masks.html for details.
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).
Adding/Rename markers (M/Ctrl-M) were restricted to only being
available when the mouse was hovering just over the time scroller at
the bottom of animation editors, as otherwise we'd get nasty keymap
conflicts where markers keymap would block all the primary function
keymaps.
However, in the case of Adding/Renaming markers, there are no other
keys which currently conflict with these in such cases. Hence, it is
fine to let these ones be able to be run from anywhere within the
animation editors, which should make it easier to add markers for
lipsyncing purposes again for example.
blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.

From the patch description:
ValterVB on #blendercoders submitted a long list of missing tooltips in Blender, and I went through the list and added all I knew. After that I crowdsourced the rest by putting a spreadsheet on Google docs and having people fill in the missing ones that I didn't know. So if there's some weird tooltip in there that doesn't make sense, that's why.
Thanks to Wolter, spacetug and others on BlenderArtists for contributing tooltips.
- In Drivers mode of Graph Editor, expanders for sub-object data were
not working at all. This was because they were getting overriden by an
errant ob-level drivers check
- Adding drivers from py-api didn't update Graph Editor
- made EXPANDED_AGRP take bAnimContext as an argument.
- remove unneeded NULL check drawFacesColored functions.
- comment some vars which are set but not used.
- ghost C api, BLI_get_folder_version() could assign garbage values.
- pointcache ptcache_find_frames_around() had a superfluous NULL check which would have crashed anyway if actually NULL.
- remove some warnings
- fix typos
- cmake allow in-source build (when WITH_IN_SOURCE_BUILD is defined)
- cmake, use an explicit list of rna files (don't glob)
Using search for operators showed ambigious names like "Duplicate" or "Delete".
Default names should give at least a descriptive label. In case operators
are collected in a group name-shortening should be handled separaly.
On anim-render, a click in timeline stopped render completely.
The reason for this was a bit wacko code to cope with frame-step
feature (steps of multiple frames).
I thought of fixing that, but instead decided to block any operator
in Blender to change a frame while a render is in progress.
Both render engine and UI are accessing (writing to) the same
data then, which is a bad conflict.
Still a serious weakness of threaded render, but I'll keep
trying to allow this as far as possible :)
