* #19727: Noise modifier does nothing with size 1.0
When the 'Size' and 'Phase' parameters were both 1.0 exactly, and evaltime was an integer (as is the case when doing animation evaluation but not for Graph Editor drawing), the noise calculation function was bailing out. Now, the 'z' component supplied to this function is a decimal value (hardcoded to 0.1 after experimentation) to try and avoid this situation.
* Graph Editor 'Bake' operator was using wrong poll callback, making it useless when trying to use it on a F-Curve that only has modifiers on it (i.e. the main use case of the operator!)
* The python 'math' library is now included in the py-namespace used to evaluate button expressions. So it is now possible to do 'radians(somevalue)' to get a rotation value that Blender can understand...
* Shapekey path getting function now uses the appropriate wrapper for grabbing the pointer to the ID block for the ShapeKey
* Made the Graph Editor's minimum zoom size finer...
* Submenus displaying the options available for certain operators now will now show the hotkey for the operator on the menu entries.
* Added an option for mirroring keyframes in the Graph Editor which makes use of the new cursor
It is now possible to choose from 'Bounding Box' (default), '2D-Cursor', and 'Individual Centers' as the pivot point(s) that rotation/scaling is performed around.
Moving out a few gl state changes to higher-level calls to improve performance when drawing handles. This already improves the responsiveness a lot on a few files, though a few other tweaks will also help.
I've finally given in, and implemented a '2d-cursor' for the Graph Editor. This is simply represented as an additional horizontal line that meets with the current frame indicator, forming a cross-hair. It can be disabled from the View menu.
Currently, the only tool which takes this into account is the Snapping tools (Shift-S), where I've hooked up a tool I added some time ago.
TODO:
- expose this cursor to the transform tools for scaling/rotation options...
Toggling one of the visibility toggles in the Graph Editor now flushes the new value up/down the hierarchy.
- when enabling a visibility toggle, all the 'higher' up and lower down channels get their visibility turned on
- when disabling a visibility toggle, only the ones lower down get their visibility turned off (since there might still be other channels at the same level which are still enabled.
This makes showing/hiding groups of F-Curves much easier, since previously you'd have to use multiple clicks to isolate particular F-Curves. For example, to isolate only X Location curves, previously, the workflow would have been to select all AKEY, hide all VKEY, then toggle the individual X Location curves in group, then make sure the groups and objects, etc. were also visible. Now, the steps of making sure that the parents were visible too has been eliminated.
---
Also, fixed a few minor bugs with the animation-backend code for Graph Editor.
* Tiny tweak of GL commands used when drawing F-Curves (single GL_LINES instead of multiple GL_LINE_STRIPS) to hopefully improve the performance with heaps of handles drawn a bit
* Spelling fix for initTransDataCurveHandes -> initTransDataCurveHandles
Added a base-template for editing/creating RNA-Paths. This is now used for KeyingSets and Driver UI's, so that when the actual magic gets put in, it will work.
* Converted Drivers UI to mostly use the Layout Engine
* All the buttons that perform actions are not operators yet (the code for that would be quite icky still)
* I've added some (commented out) calls for the property definitions of Driver properties to perform Depsgraph updates. I've left these commented out until we have the option to turn off auto-updates, since with driver editing, that could be very dangerous.
* Drivers can now (in theory) use any ID-block, using the Any-ID template added earlier. However, be warned that the stupid depsgraph won't be able to cope with most of these cases.
TODO:
- more fancy widgets for RNA-Path and Index will come later
belongs here still, but this came up often, it avoids having to
switch tabs a lot when creating things.
Also renamed uiLayoutFreeBlock to uiLayoutAbsoluteBlock.
Keymaps are now saveable and configurable from the user preferences, note
that editing one item in a keymap means the whole keymap is now defined by
the user and will not be updated by Blender, an option for syncing might be
added later. The outliner interface is still there, but I will probably
remove it.
There's actually 3 levels now:
* Default builtin key configuration.
* Key configuration loaded from .py file, for configs like Blender 2.4x
or other 3D applications.
* Keymaps edited by the user and saved in .B.blend. These can be saved
to .py files as well to make creating distributable configurations
easier.
Also, user preferences sections were reorganized a bit, now there is:
Interface, Editing, Input, Files and System.
Implementation notes:
* wmKeyConfig was added which represents a key configuration containing
keymaps.
* wmKeymapItem was renamed to wmKeyMapItem for consistency with wmKeyMap.
* Modal maps are not wrapped yet.
* User preferences DNA file reading did not support newdataadr() yet,
added this now for reading keymaps.
* Key configuration related settings are now RNA wrapped.
* is_property_set and is_property_hidden python methods were added.
* Code for generating 'Object' summary of Keyframes for DopeSheet (which is also used by the TimeLine for getting keyframes to draw) now considers materials, object data, and particles too.
* Rearranged the way that keyframing-related settings were presented in the User Preferences. The way the settings were grouped was plain confusing, and based on biased views from the old system. For the record, 'needed'+'visual' are always considered when inserting keyframes, 'always' is for autokeyframing, and default interpolation is only used for newly created F-Curves.
* Fixed bug #19472 - Scroll wheel scrolls in the wrong direction for enum-menus that were flipped (i.e. window type menu and 3d-view mode selector).
This (biggish) commit generalises the rotation modes functionality added for Bones, allowing Objects to use the various Euler Rotation orders, Axis-Angle, and Quaternion rotation representations.
I've also cleaned up the nomenclature of the rotation-related settings so that the naming styles are more consistent with each other. Unfortunately, this will break all files involving object or bone rotation animation made in 2.5 versions (2.4x will still get correctly converted).
General Notes:
* By default, Objects still default to using Eulers, while Bones will use Quaternions by default still.
* I've fixed all areas that I'm currently aware of to work with these changes. However, there are probably a few places where I've missed a few changes (i.e. auto-keyframing will need attention later).
* Removed the old "IPO-Keys" stuff from Transform code. I'm unlikely to restore this in the near future, and trying to fix that to include support for this commit would have been too much work.
* Added missing RNA wrapping for Scene -> AnimData
* Fixed bug (with temp-fix) where sequence strips with no names couldn't be animated properly. Currently, this will just use the index of the strip, although that is likely to be mutable (adding/removing strips will change it).
* Removed some old unused code from action.c
Main Feature:
* It is now possible to choose which AnimData block is the 'active' one for editing, and/or select them too. AnimData blocks are generally the dark blue and lighter-blue expanders (i.e. Scene, Object, Camera, Lamp, Curve, Armature, etc.)
* Objects are no longer selected/deselected when AKEY is used to toggle selection of channels. This was getting a bit annoying.
* Following on from selection of AnimData blocks, it is now possible to select/make active an AnimData block in the animation editors, and change the active action for that block via the 'Animation Data' panel in NLA Editor's properties region.
--> Be aware that user-counts are not totally handled correctly there yet, so some funky behaviour might be seen...
--> It is possible to assign a new action, or to assign an existing one, allowing to switch between actions as in the past with Actions/IPO Editors...
Other tweaks:
* Some code tweaks towards making the 'Euler Filter' feature for Graph Editor working sometime soon
* Added some backend code for snapping the values of keyframes to a single value. Still need to work out some UI for it though.
* Shuffled the code for ACT_OT_new() around, and removed the poll() callback so that it worked in NLA too.
* Fixed some more notifier bugs with deleting bones and a few other editmode operations for Armatures.
* All the selected F-Curves will get the same type of F-Modifier added.
* The button in the properties region will still only added the F-Modifier to the active F-Curve though
* For now, there must be an active F-Curve in either case, otherwise the poll() callback fails.
* Deselect all now selects/deselects F-Curves too
* Tangents of unselected F-Curves now draw 'faded' like the curves they belong to. This experimental change is quite subtle, but can be made stronger still if people want.
* Cleaned up some old comments in the code too...
* Updating Preview Range settings results in correct updates for Animation Editors
* Compositing nodes now correctly animate when the values were set by IKEY/RMB on suitable node parameters. Beware that these nodes are not relinkable node-trees, hence the standard code not working.
* Ctrl-P to parent objects to bones now works in Pose Mode too. I needed to add a special keymap entry for this, though I thought this would have been better to be automatically inherited/present from Object keymap already?
* Ctrl-P -> Parent to Bone option now works correctly again. 1.5 lines of code missing here...
* Breakdowns tool now shows custom cursor during 'modal' phase so that it's not that confusing what's going on.
their handlers based on notifiers, which is simpler and more
reliable.
This fixes for example editmode or uv edit keymaps not working
when creating a new 3dview or image space.
* Removed some legacy code which is not needed anymore now.
* Move some test_*poin_but functions to logic space code,
since that's the only place using it still.
* uiIconFromID now uses RNA info to lookup the icon, to avoid
code duplication, and means it works for more ID types.
#19345: can't get out of grayed out pointer field.
#19342: item_pointerR fields can't be cleared with one item.
#19341: fix hanging tooltips when manipulating regions.
#19339: context panel still allowed tabbing, but it has no header.
#19334: editing SSS settings crashed previewrender.
#19330: object mode could not be switched on from the header menu.
* Mesh Deform modifier now correctly shows Bind/Unbind buttons. Previously, only Bind got shown...
* Selecting keyframes in the Graph Editor using Border Select now allows the keyframes to be editable afterwards. Previously, the curves weren't getting selected afterwards, therefore, the poll operators would skip those curves.
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
* 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.
It is now possible to tag certain keyframes as being 'breakdowns' in the DopeSheet. Breakdown keyframes are drawn as slightly smaller blue diamonds.
Simply select the relevant keyframes and use the RKEY hotkey (or from the menus, Key->Keyframe Type) to choose between tagging the keyframe as a 'proper' keyframe and a 'breakdown' keyframe.
Notes:
* Please note that this feature does not currently imply anything about breakdowns moving around keyframes or behaving any differently from any other type of keyframe
* In future, if there is any such need, more keyframe types could be added, though this is not really likely at all
The 'Show Sliders' option for DopeSheet and Graph Editors now works again. When this option is enabled (it is disabled by default), a slider (or combobox) is shown beside the mute/lock toggles for F-Curves. Editing the slider will result in a new keyframe being added on the current frame.
So, for all the (ex)-Maya animators out there, you can now animate in a channelbox-like way. :)
Also in this commit:
* Fixed some warnings in modifier.c from previous commits there
* Fixed some refresh problems with DopeSheet channel list (which were only obvious after adding back the sliders)
* Removed the old/unrestored and nasty slider code used in the past by the Action Editor only.
when passing properties=True as argument.
Other changes:
* uiItemR, uiItemFullR, uiItemFullO now accept a flag argument rather
than multiple different "boolean" arguments, but still exposed as
booleans to python.
* Fix RNA to support setting PROP_RNAPTR for return values.
* Fix header menu spacing bug, and make it consistent for all headers.
* For consistency, always put menus first in the header, then any enums
to switch the type of data displayed.
* Node editor header ported to python layout. Still quite a few
operators missing to make the menus complete.
* RNA wrapped node editor, and added use_nodes property to material
and scene.
Alpha for icons wasn't getting set correctly in animation editors anymore. This commit should fix the issues there, though the scrollbars still have a few minor issues still too.
Also, NLA strips with repeats now have the repeat indicators drawn only 80% or so of the height, making it easier to distinguish between strips with repeats and bunches of strips.
Now the mute/protect/expand/etc. toggles are drawn using UI widgets. This means that special event handling code to determine when they were clicked on is no longer needed, and also means that there can now be tooltips for these items too.
Also, added visibility toggles for ID-block expanders, which will cause all the F-Curves in the linked datablock to not get drawn. The backend filtering code to make this work will come later...
* Fixed padding for Graph Editor visibility toggles
* Reverted many of the tweaks to Timeline UI for now (for the reasons outlined in earlier mail)
* NLA Editor now (mostly) uses the new channel-drawing API
Finally started refactoring the drawing code for animation editors so that all the drawing (of the channels/names list) is done using standardised code for all the editors.
A little specialised system for this has been made, and is now used for DopeSheet and Graph Editor drawing. This should make it easier to add new channel types with less effort.
Protect/mute toggles are now always clamped to the right-hand edge of the channels list. So you can now make the list wider to view longer names fully. However, since the mouse-handling hasn't been fixed yet, this won't always work.
TODOs:
* make mouse-click handling code use this system too, simplifying things to 1-2 lines of code there. Maybe this could be made to use UI widgets instead at a later date?
* NLA still needs to be ported to this system
* Tools such as set handle type, etc. were not being called correctly from the menus. There were missing operator-context calls to make sure that the invoke methods would get skipped.
* Hack for loading old files - buttons region for Graph Editor now gets added. Dunno why this didn't work automatically as for NLA despite the two having the same code.
* Animated ShapeKey F-Curves/Drivers are now visible in the Animation Editors.
* As a result of this, the old 'ShapeKeys' mode (which would display all the shapekey channels, even if they had no keyframes yet) in the DopeSheet, no longer works for now. However, it would have been of no use as no sliders were shown anyway.
* Drivers which depended on the rotation of bones now work again. These now point to the right RNA properties, and get some extra 'time' corrections (for degrees -> radians change).
* When resizing the window, the top position is now preserved,
instead of the center position.
* Fix zoom level not being preserved in various cases, when
changing both with and height. This replaces some earlier code
which did this at screen level but wasn't very reliable.
* Different tabs now each preserve their own scroll.
* When switching between tabs, it now scrolls to show as many
buttons as possible, instead of possibly showing empty space.
There is a trade-off here between doing that keeping the
buttons in the same place, no ideal solution exists I think.
* Change zooming in/out to be symmetric, for example doing
numpad + then - did not give the original zoom level back.
* Added some calls to avoid hanging tooltips when manipulating
the view.
Internals:
* Added V2D_KEEPOFS_X and V2D_KEEPOFS_Y to keep the top/bottom
rather than the center.
* Renamed V2D_KEEPZOOM to V2D_LIMITZOOM (seems more appropriate),
and make V2D_KEEPZOOM preserve the zoom level.
* Cleaned up some parts of the code that were unused/could be done a bit nicer
* Added a new option for only showing the keyframes of the selected F-Curves in the Graph Editor, as another way of reducing the clutter.
