Suposedly usefull for creating trees of objects (where objects have very diferent size-NumFaces and shape-BB)
Altought the implemented costs maybe not be very correct (for now), as i didnt cared about following a specific "corrected" model
* Rename BIF_transform/retopo.h to ED_transform/retopo.h
for consistency.
* Move MESH_OT_duplicate_add to editmesh_add.c.
* Remove some code from BIF_gl.h which is not needed there
anymore.
* Context panel now draws without header, with arrows, no scene name.
* Softbody vertex group search popup.
* Improve names for autogenerated shortcut keys in menus.
* Make most Select menus in the 3D view header work.
* Fix armature border select selection syncing.
* Add POSE_OT_select_constraint_target,
MESH_OT_select_by_number_vertices, MESH_OT_select_vertex_path.
* Merge mesh select similar into one operator.
* Don't give MESH_OT_select_random Space hotkey.
* Add DAG_object_flush_update to many mesh edit tools, not calling this
will crash with modifiers.
* RNA_def_enum_funcs for dynamic enums in operators, but not very useful
without context yet.
* Fix refresh issue with image window header + editmode.
* Fix drawing of shadow mesh for image painting.
* Remove deprecated uiDefMenuButO and uiDefMenuSep functions.
* Remove keyval.c, code is in wm_keymap.c already.
* Rename WM_operator_redo to WM_operator_props_popup.
Brought back the basics for transform manipulators. Martin will
hook it all up to new transform system.
Some notes:
- Still uses G.moving
- BIF_do_manipulator() is called as a View3D Operator
I've tested selecting handles, added a print to confirm
- BIF_GetTransInfo() returns a dummy struct now, just to get
it running.
- Marked some other issues with XXX
* Text labels on NLA-Strips should now draw properly for most short-strips now. Previously, the padding on the text was a bit too extreme, so for very short strips (less than 4 frames or so), the text was often pushed down into the bottom-right corner of view.
* Optimised the keyframe-highlighting code for buttons a bit. Replaced the custom linear-search with the binary-search used when inserting keyframes (and for the 3d-view keyframe-indicator). There should be some theoretical improvements due to this at least...
* base was referenced before NULL check
* ob wasn't checked for NULL
Still broken: Add Mesh doesn't seem to work in Object Mode.
But now it doesn't crash anymore...
* When influence/time for NLA-strips are animated, settings in the other panels which used to control these are now greyed out to show that they won't have any impact over the result.
* NKey panel for Graph Editor now opens on Right-Hand Side, just like for NLA Editor. The small sub-region above the Channels region was too troublesome to work with.
* These settings can now be edited + keyframed (using IKEY over the button only for now... other cases will fail)
* Reshuffled some of the keyframing code to make this sort of thing easier to do. Also, restored corrections for NLA-mapping when inserting/removing keyframes.
TODOS:
* animation editors don't show these keyframes yet
* the buttons don't change colour yet to reflect this state. How to do this efficiently?
* allow keyframing of these in more places
* more robust UI handling for this.
NOTE: transition strips can only be added between two selected action-clips that have a gap (but no other strips) between them, and are in the same track.
I think its something like:
old was: 4*nlogn + 3*(n*6)
new is: (2*nlogn + 3*(n*6)) * f, with f<1
Still missing changing the sorting function to an introsort instead of qsort
Other options like bucketing sort may be worth trying (for very large trees)
- Scrollers now only disappear for regions with a fixed total view, like
lists, buttons, channels. More or less infinite views keep scrollers to
indicate that you can still pan or zoom further.
- Nodes: put back SHIFT+D "Add duplicate"
(Also fixed duplicate objects menu name... it should be a bit more
descriptive)
only for 2childs splits
with "worse case heuristic" means each child is considered to have a cost linear on the number of leafs
no termination criteria
number of BB test/hits expected to "reduced" by some factor
tree building is also expected to be slower as previous split was "object mean", which is quite fast to evaluate
F-Modifiers now work on 'all' types of NLA Strip. To get them working on Meta-strips, F-Modifiers on the Meta strip must be applied on top of those for child strips. For now, this is done by joining the lists of modifiers, and evaluating the joined list.
Currently, Transitions don't work that great with F-Modifiers yet (only the endpoints get evaluated with the F-Modifiers). Solving this is for another time...
Previously, the quick-hack I coded for Meta-strips evaluation didn't really take into account the possibilities to use Meta-Strips as strips in their own right - i.e. reversed, muted, time-mapping-curves, influence-blending - were all unavailable.
This commit makes the aforementioned capabilities of other strips available for Meta-Strips too. The evaluation is now kind-of recursive (as with most of the other methods which take them into account) so that each 'level' of strips get evaluated correctly within their frame-of-reference.
TODO:
* F-Modifier support for Metas...
Strip-sorting code was buggy, as it was trying to access an invalid pointer, so the call to sort strips after transform was temporarily disabled in previous commits.
I needed this to make sure that BKE_copy_images works properly,
probably will be useful in future.
Using Check framework (http://check.sourceforge.net/doc/check.html/index.html).
WITH_BF_UNIT_TEST option builds 'alltest' program under [BUILDDIR]/bin,
which, when executed, runs unit tests, currently only 1.
Example output:
----------------------------------------------------------------------
Running suite(s): Image
0%: Checks: 1, Failures: 1, Errors: 0
tests/alltest.c:74:F:Core:test_copy_images:0: Expected //bar/image.png to be translated to /tmp/bar/image.png, got /tmp/bar/image.pn.
----------------------------------------------------------------------
Spent lots of time (a couple of days actually :) to figure out how to
link the test program with Blender libraries. As it turned out there
are circular dependencies among Blender libraries. GCC by default
doesn't expect circular dependencies - dependant libs should precede
libs they depend on.
The magical --start-group linker option helped to solve this
(http://stephane.carrez.free.fr/doc/ld_2.html#IDX122).
Also:
- added bpy.util module. bpy.sys.* functions will move here later
- added bpy.util.copy_images that uses BKE_copy_images
- export_obj.py uses bpy.util.copy_images
Animations can now be played back in reverse, by clicking on the reversed-playback button in the TimeLine header beside the play button (NEW ICON NEEDED HERE).
I'm not sure how well this works with sound, but from what I gather, this can be quite useful for animators to use.
* Previous/Next Folder browser
* bugfix: "open most recently opened directory".
* Previous and Next functionalities:
- use BACKSPACE to navigate to previous folders
- use SHIFT+BACKSPACE to navigate forward
- once you change the folder by other ways the forward folder list is cleared
* bug fix: the sfile->params->dir set through ED_fileselect_set_params wasn't correct. According to the code taking the settings from the existing (previous) filebrowser is a temp solution. In that case this is a fix for a temp solution :)
(changes in: wm_event_system.c, filesel.c and ED_fileselect.h)
** Andrea(elubie): we can get away of the folderlist_clear_next test if we manually pass a boolean to file_change_dir (e.g. file_change_dir(sfile, true)). I tried not to mess up with your changes here. It's slightly slower (and maybe hacky) but its's more conservative IMHO.
(my first commit to 2.5 ... that was a good reason to put my paper on hold :p)
This commit is quite experimental, and might have to be reverted, but in quite a few places, the cleanups from this commit were already necessary.
* I've left most of the image-handling functions alone, since I'm not sure how well they cope with negative indices.
* Start/End frames cannot be negative for now... any specific reasons why they should be negative?
* The code to move strips between tracks now works (though it can still be a bit too eager to change tracks half-way through some transforms).
Strips are moved up/down one strip at a time, depending on whether there is any space in the next-track in the direction you direct it to move in.
* Auto-snapping works again. Also enabled snap-to-marker option for Graph Editor here.
Recoded the Transform code for NLA-Strips so that they can now be moved between strips and will not get truncated when they get moved into other non-moving strips.
Todos:
* The current code for moving strips between tracks is buggy (only goes up, and has a tendency to move up without being told to)
* Auto-snapping doesn't work yet...
* Chains of selected strips are now converted to meta-strips before transforms begin, and converted back afterwards. This simplifies the transform code needed in later stages...
* Transform-flushing code for Meta-Strips should now work. There seems to be a little bit of numeric inaccuracy problems somewhere, as two strips which met at the same frame can get separated when scaling.
* Meta-strips now draw with proper text identification
* Snapping strips now properly clears meta-strips if a moved strip needs to be moved into a new track to be accomodated.
* Fixed a filter used by a selection-operator.
*"Added" SCE_PASS_RAYHITS to visually see each pixel primitive and BB tests (not-completed for UI)
*Added runtime exchange of tree structure
*Removed FLOAT_EPSILON from BLI_bvhkdop BB's
* Split strip (YKEY) now plays nicely with Transitions and Metas. Meta strips get split up into their child strips, while transitions are ignored.
* Wrapped Meta_Strip->strips in RNA
* Bugfixes in Meta-strip API functions to silence some runtime-errors...
* Added several API functions for Meta-Strips editing. One of these (flush transform) still needs a few tweaks before it does its job well enough for all cases.
* Meta strips are now drawn with a purple-ish colour. The start/end points of the strips they encompass are shown with lines along the length of the strips, with lines starting from the top indicating start-points and lines starting from the bottom indicating end-points.
* Meta strips can be made (i.e. strips can be assigned to meta-strips) by selecting some strips and pressing Shift-G.
Meta strips can be removed by selecting some meta-strips and pressing Alt-G.
* Strips can now be 'snapped' to start from: the current frame, the nearest frame, the nearest second, or the nearest marker; using the Shift-S hotkey.
'Islands' of adjacent selected strips occurring in the same track are moved together as a single strip so that the start-point of the first strip is on the sepcified time, but all the relative lengths of strips stay the same. Internally, temporary meta-strips are created to facilitate this.
Refactored the backend code/API's to support 'meta' strips (i.e. strips containing other strips). These have been implemented to be nested to 'unlimited' depths (in terms of common usages that is, though there is a very remote chance of stack-overflow in theoretrical evil cases only that shouldn't ever be encountered in production).
This paves the way for implementing the necessary tweaks needed for the transform code (in addition to some cool user-level tricks)
* bringing back file numbering operator (PADPLUSKEY, PADMINUS)
* Note: discovered conflicting key with View2D zooming that causes it to not work in panel area.
