Keyframes are now prepared for drawing by being added to a binary-tree structure instead of using insertion-sort on a Double-Linked List. This gives rather significant improvements on a few bad cases (*).
I've implemented a basic Red-Black Tree whose nodes/data-structures can also be used as a simple Double-Linked List (ListBase) for this purpose. The implementation of this tree currently does not have support for removing individual nodes, since such capabilities aren't needed yet.
Stats (using keyframes from an imported .bvh animation file):
* When only the keyframes are drawn (i.e. long keyframes are not identified), the time needed to draw the DopeSheet region 10 times went down from 4000ms to about 300ms.
* When long keyframes are considered as well, the same test has gone from 6000ms to 3000ms. There is still a bottleneck there that I haven't been able to remove yet (an attempt at this made the runtimes go through the roof - 32000 ms for the test done here).
Assorted Notes:
* Added missing headers for some files
* Fixed profiling flags for mingw. There was an extra space which prevented the sound-code from compiling.
* Renamed the 'blend' blending mode to 'replace', since that's what it usually does
* Drawing a darkened rect behind the keyframes shown in the action line
--
* Fixed typo made last night which broke compiling
* Consolidated all the keyframe-shape drawing code to use a single codebase. Even if we don't ultimately go with OpenGL keyframes, there's always a tidy option for that now.
* Removed the glaMapping stuff in favour of remapping the keyframes manually. The old code was causing some mess, and not really working well for the DopeSheet with various mappings being used.
* Fixed NLA-mapped selection in DopeSheet. Clicking on individual keyframes should now work ok. More testing required though.
* Keyframes in DopeSheet are now drawn fully using OpenGL (instead of icons). They look less tactile now, but this may be compensated with in terms of speed? Previously I disabled this type of drawing due to issues with some cards. Enabled again for now, but mainly because I couldn't get the icons to line up nicely in screenspace...
* Borderselect in DopeSheet. I've had a look at issues with it selecting the wrong channel's keyframes. The issues don't seem to be solved yet though... will look again tomorrow.
In TweakMode, the keyframes of the Active Action are now shown (and can be edited) in NLA-mapped time, with appropriate corrections applied when editing. This works in the DopeSheet and Graph Editors :)
To do this, got rid of the old wrappers/API-methods, replacing them with new-style ones. A few methods previously (in this branch) used only for evaluation are now used for this purpose too. As the same code is used for editing + evaluation, this should now be much better to work with.
I've only done a few brief tests now, but I think I might've muddled the invert-flags on one or two cases which I'll need to check out tomorrow. So, beware that there may be some weird and critical bugs for the next few days here...
Also, added proper license headers to new NLA files.
TODO:
- testing + bugfixing due to this commit
- show range of keyframes in NLA Editor active-action line
Grand cleanup:
- removal of FTF and ftfont dir
- removal of text.c which wrapped it
- wrapped old text drawing code temporarily, need to decide how 'style'
will behave per editor when you draw strings outside interface code....
wouldn't be very useful to set fonts locally all over?
* Scene and World AnimDatas are now included in animation editors
* Keyframes for integer-value settings now get the FCURVE_INT_VALUES flag set for their F-Curves, which restricts those curves to only having integer-values. F-Curve displays have been altered accordingly, but some editing tools may still need tweaks to work with this.
* Fixed notifiers for Insert Keyframe -> Active Keying Set.
* Streamlined the filtering code to remove a few redundant options, which required tweaking the code for most tools
* F-Curves are simply displayed using their full paths right now. This should eventually be the UI-string stored in RNA, but right now there are still a few missing things.
* There are a few tools which are not available yet which were available in 2.5 before Animato was added:
- Copy/Paste
- Rearrange channels
Also, the DopeSheet is not totally functional (in terms of displaying animation data for sub-object data yet). That will be added tomorrow.
* Added 'Action Group' pointer to F-Curves, as it will be handy for allowing Bone channels to still remain grouped as they were before with the Action Channels. However, reintroducing such a structure to the data-storage is not anticipated...
* Added the relevant filtering necessary for this to work, into the animation-channel filtering code.
* Updated most of the keyframe-editing tools to respect this
* Renamed keyframe-editing API loopers (added ANIM_ prefix) for consistency
* Added function for mapping keyframes to/from NLA-mapping for Ipo-Curves in addition to the one for IPO blocks. As a result, renamed the latter for consistency.
* Dopesheet - clicking on keyframes in Object channels (if they came from Object-Data such as Lamps, etc.) would crash. I noticed this error in AnimSys2 yesterday
* Action Editor - do versions code now totally reinitialises the Action Editor View2D data (for the timespace), since I found a few files where there appeared to be some weird settings set.
* RNA Browser (Outliner->Datablocks) would crash when the Area was ripped (using Alt-R hotkey) as seen in mfoxdogg's 2.5 Tour 2
It is now possible to select individual keyframes again in the Action Editor.
* Temporarily disabled markers keymap in Action Editor, as it was stealing all the events. Waiting for solution from Ton...
* Fixed a crash and wrong coordinate conversion errors
* Brought back backend for editing keyframes IPO/IPO-Curves. Did some refactoring work here that will still have to be verified when operators using them are added.
* Animation channel filtering code now returns the number of channels filtered (for Action Editor to set totrect of channels - TODO still!)
* View2D - made function to check if mouse is in View2D scrollers an API function
* Renamed keyframe related files. The old names were too clumsy.
* Started porting click-select operators for Action Editor. These don't work currently, as the events are being stolen by the markers. This needs to be fixed ASAP.
