Aim was to get a total refresh of the animation system. This
is needed because;
- we need to upgrade it with 21st century features
- current code is spaghetti/hack combo, and hides good design
- it should become lag-free with using dependency graphs
A full log, with complete code API/structure/design explanation
will follow, that's a load of work... so here below the list with
hot changes;
- The entire object update system (matrices, geometry) is now
centralized. Calls to where_is_object and makeDispList are
forbidden, instead we tag objects 'changed' and let the
depgraph code sort it out
- Removed all old "Ika" code
- Depgraph is aware of all relationships, including meta balls,
constraints, bevelcurve, and so on.
- Made depgraph aware of relation types and layers, to do smart
flushing of 'changed' events. Nothing gets calculated too often!
- Transform uses depgraph to detect changes
- On frame-advance, depgraph flushes animated changes
Armatures;
Almost all armature related code has been fully built from scratch.
It now reveils the original design much better, with a very clean
implementation, lag free without even calculating each Bone more than
once. Result is quite a speedup yes!
Important to note is;
1) Armature is data containing the 'rest position'
2) Pose is the changes of rest position, and always on object level.
That way more Objects can use same Pose. Also constraints are in Pose
3) Actions only contain the Ipos to change values in Poses.
- Bones draw unrotated now
- Drawing bones speedup enormously (10-20 times)
- Bone selecting in EditMode, selection state is saved for PoseMode,
and vice-versa
- Undo in editmode
- Bone renaming does vertexgroups, constraints, posechannels, actions,
for all users of Armature in entire file
- Added Bone renaming in NKey panel
- Nkey PoseMode shows eulers now
- EditMode and PoseMode now have 'active' bone too (last clicked)
- Parenting in EditMode' CTRL+P, ALT+P, with nice options!
- Pose is added in Outliner now, with showing that constraints are in
the Pose, not Armature
- Disconnected IK solving from constraints. It's a separate phase now,
on top of the full Pose calculations
- Pose itself has a dependency graph too, so evaluation order is lag free.
TODO NOW;
- Rotating in Posemode has incorrect inverse transform (Martin will fix)
- Python Bone/Armature/Pose API disabled... needs full recode too
(wait for my doc!)
- Game engine will need upgrade too
- Depgraph code needs revision, cleanup, can be much faster!
(But, compliments for Jean-Luc, it works like a charm!)
- IK changed, it now doesnt use previous position to advance to next
position anymore. That system looks nice (no flips) but is not well
suited for NLA and background render.
TODO LATER;
We now can do loadsa new nifty features as well; like:
- Kill PoseMode (can be option for armatures itself)
- Make B-Bones (Bezier, Bspline, like for spines)
- Move all silly button level edit to 3d window (like CTRL+I = add
IK)
- Much better & informative drawing
- Fix action/nla editors
- Put all ipos in Actions (object, mesh key, lamp color)
- Add hooks
- Null bones
- Much more advanced constraints...
Bugfixes;
- OGL render (view3d header) had wrong first frame on anim render
- Ipo 'recording' mode had wrong playback speed
- Vertex-key mode now sticks to show 'active key', until frame change

To enable it you will need to download OpenEXR and install it.
For the Makefiles you will need to set WITH_OPENEXR=true
and set NAN_OPENEXR to point to where OpenEXR is installed.
For scons you'll need to remove config.opts to get the new options
so you can enable OpenEXR, I was not able to get blender to link
with scons so the scons stuff may need to be tweaked a little but
I think it should work.
For other platform managers The OpenEXR stuff is similar to QUICKTIME
you need to define WITH_OPENEXR and setup the library stuff and
as you'll notice in this commit there are two extra files.

patching versions for UI settings.
Currently four different levels of routines for .blend file reading exist;
/* interface level */
1) BIF_init() -> calls 3
2) BIF_read_file() -> calls 11, optional 4
3) BIF_read_homefile() -> calls 11 or 12, and then 4
4) init_userdef_file()
/* kernel level */
11) BKE_read_file() -> calls 21, and then 14
12) BKE_read_file_from_memory() -> calls 22, and then 14
13) BKE_read_file_from_memfile() -> calls 23, and then 14
14) setup_app_data()
/* loader module level */
21) BLO_read_from_file() -> calls 24
22) BLO_read_from_memory() -> calls 24
23) BLO_read_from_memfile() -> calls 24
/* loader module, internal */
24) blo_read_file_internal()
Note:
- BIF_read_homefile() has additional UI initialize calls, like windows fullscreen and executing commandline options
- Reading from memory (12) only happens for the compiled-in .B.blend
- The "memfile" here is a name I gave to the undo "file" structure. Which is constructed out of memory chunks with basic compression features.
- the kernel function setup_app_data() sets globals like "current screen" and "current scene".
So far, so good. The levels as mentioned here clearly distinguish UI from kernel, and should enable for example game loading (runtime) or background (no UI) loading. In the past years however, 'bad level' dependencies were added, and especially the patches for 'file versions' were added in too many places. The latter is evidently a result of the problem that the "UserDef" struct cannot be initialized/patched if there's not a need for a UI.
Here's how the flow goes in four different cases:
----- Starting up Blender, in foreground with UI --------------------
- creator/creator.c, main() -> calls 1
- If the commandline contains a filename, it calls 11
----- Starting up Blender, in background without UI --------------------
- creator/creator.c, main() -> calls 11 if the commandline has a filename
Note: no Userdef is read, nor initialized. Please note that this was already an existing problem for using Yafray, not setting proper file paths in background mode. The Yafray paths don't belong in the User menu.
----- Starting up Blender as a runtime executable --------------------
This only has calls to 22
----- Loading a file from within the UI (with F1, CTRL+O, using pulldowns) -----
Only calls allowed to 2. It detects if a UserDef has been read too, and in that case the init_userdef_file() will be executed.
Hope this is understandable :)

http://crd.lbl.gov/~xiaoye/SuperLU/
This is a library to solve sparse matrix systems (type A*x=B). It is able
to solve large systems very FAST. Only the necessary parts of the library
are included to limit file size and compilation time. This means the example
files, fortran interface, test files, matlab interface, cblas library,
complex number part and build system have been left out. All (gcc) warnings
have been fixed too.
This library will be used for LSCM UV unwrapping. With this library, LSCM
unwrapping can be calculated in a split second, making the unwrapping proces
much more interactive.
Added OpenNL (Open Numerical Libary):
http://www.loria.fr/~levy/OpenNL/
OpenNL is a library to easily construct and solve sparse linear systems. We
use a stripped down version, as an interface to SuperLU.
This library was kindly given to use by Bruno Levy.
Solaris and a bunch of the others were out of date....
I guess we should change them back for platforms that don't work out
with 2.3 but I'm guessing that things will get updated better this way
then asking everyone to update their own platforms.
Kent
libs. I turned off the automatic building of solid in extern/ for
irix since the vendor supplied build system does not work well.
Note to JW: this can be built with either mipspro 7.3 or 7.4
(I needed to archive solid with "CC -ar ..." for this to work
with 7.3).
I don't want to do this, but the new Open GL extension stuff won't
compile under Irix, and the glext.h from sgi only works under
linux/windows (Kester: can you look into a work around for this?)
or whatever):
NAN_NO_KETSJI: when set to true, disables compilation of the game engine.
NAN_JUST_BLENDERDYNAMIC: when set to true, only dynamic executable is
build (i.e., no plugin, etc).
Note that NAN_NO_KETSJI implies NAN_JUST_BLENDERDYNAMIC.
maintainers really *really* only want to use sdl11-config while not
offering sdl-config as well ...)
This patch was briefly discussed on -committers but still might break
SDL stuff.
* moved references to libSDL out of ifeq($(INTERNATIONAL), true) (win32)
and ifeq($(WITH_FREETYPE2),true) (irix) conditionals in source/Makefile
* look for sdl in $(LCGDIR)/sdl if sdl-config isn't found
thanks to LarstiQ for doing most of the work
I need to get openal working on my machine before I can test it so
if it doesn't work feel free to fix it. Hopefully this will be
the majority of the stuff though.

size of this;
Finally, the Sequencer audio support and global audio/animation sync stuff!
(See http://intrr.org/blender/audiosequencer.html)
Stuff that has been done:
./source/blender/blenloader/intern/writefile.c
./source/blender/blenloader/intern/readfile.c
Added code to make it handle sounds used by audio strips, and to convert
Scene data from older (<2.28) versions to init Scene global audio settings
(Scene->audio) to defaults.
./source/blender/include/BSE_seqaudio.h
./source/blender/src/seqaudio.c
The main audio routines that start/stop/scrub the audio stream at
a certain frame position, provide the frame reference for the current
stream position, mix the audio, convert the audio, mixdown the audio
into a file.
./source/blender/makesdna/DNA_sound_types.h
Introduced new variables in the bSound struct to accomodate the sample
data after converted to the scene's global mixing format (stream, streamlen).
Also added a new flag SOUND_FLAGS_SEQUENCE that gets set if the Sound
belongs to a sequence strip.
./source/blender/makesdna/DNA_scene_types.h
Added AudioData struct, which holds scene-global audio settings.
./source/blender/makesdna/DNA_sequence_types.h
Added support for audio strips. Some variables to hold Panning/Attenuation
information, position information, reference to the sample, and some flags.
./source/blender/makesdna/DNA_userdef_types.h
./source/blender/src/usiblender.c
Added a "Mixing buffer size" userpref. Made the versions stuff initialize
it to a default for versions <2.28.
./source/blender/makesdna/DNA_space_types.h
./source/blender/src/filesel.c
Added a Cyan dot to .WAV files. Any other suggestions on a better color? :)
./source/blender/src/editsound.c
Changes (fixes) to the WAV file loader, re-enabled some gameengine code that
is needed for dealing with bSounds and bSamples.
./source/blender/src/editipo.c
./source/blender/src/drawseq.c
./source/blender/src/editnla.c
./source/blender/src/space.c
./source/blender/src/drawview.c
./source/blender/src/renderwin.c
./source/blender/src/headerbuttons.c
- Created two different wrappers for update_for_newframe(), one which scrubs
the audio, one which doesn't.
- Replaced some of the occurences of update_for_newframe() with
update_for_newframe_muted(), which doesn't scrub the audio.
- In drawview.c: Changed the synchronization scheme to get the current audio
position from the audio engine, and use that as a reference for setting
CFRA. Implements a/v sync and framedrop.
- In editipo.c: Changed handling of Fac IPOs to be usable for audio strips as
volume envelopes.
- In space.c: Added the mixing buffer size Userpref, enabled audio scrubbing
(update_for_newframe()) for moving the sequence editor framebar.
./source/blender/src/editseq.c
Added support for audio strips and a default directory for WAV files which
gets saved from the last Shift-A operation.
./source/blender/src/buttons.c
Added Scene-global audio sequencer settings in Sound buttons.
./source/blender/src/sequence.c
Various stuff that deals with handling audio strips differently than
usual strips.
Removes ssl from blender.
makes the following directorys not needed anymore:
blender/intern/keymaker
blender/source/blender/src/pub
blender/source/blender/encrypt
blender/source/blender/decrypt
blender/source/blender/sign
blender/source/blender/verify
It works with The Nan Makefiles and autoconf, could whoever is working
on the other build systems update them so we can nuke those directorys?
They won't do anything but I figured I'd leave them in for a week or so
to make things easyer on people.

Florian Eggenburger).
Full instructions are in doc/README.windows-gcc.
Main differences from Florian's patch:
- the 'lib' dir should now be the same level as the 'blender' dir (rather
than being a subdir of 'blender'). This is consistent with the other
platforms that bf-blender supports (tuhopuu will also adopt this convention
hopefully soon).
- the script 'free_windows-env.mk' is no longer needed ... see the
docs about how this is overcome (again, tuhopuu will hopefully
also follow this route soon).
- the dlltool dir has it's own Makefile that builds all of the
needed stub libraries from the dll's in cvs.
#include <QuickTime/Movies.h> instead of #include <Movies.h> on OS X to
avoid having to specify the full path to the QT headers in the Makefiles
#undef NDEBUG on OS X to avoid errors about ID being declared twice
enable support for QuickTime in the original Makefiles on OS X
and there is a block at the very end for platforms not specified above.
(not all of the defintions are in the platform's for example there
is no need for export NAN_IKSOLVER ?= $(LCGDIR)/iksolver
to be repeated all over the place, all of the ones you'll probably
want to change are in the platform specific blocks though)
This allows all platforms to be overridden by env vars...
Kent
lib/ and came from extern/ (which isn't in the new repository at all)
So use stuff like:
ifeq ($(OS),freebsd)
export NAN_OPENSSL ?= /usr
else
export NAN_OPENSSL ?= $(LCGDIR)/openssl
endif
Hans
same thing:
Added the xpcom include and added a flag to use mozilla vs netscape.
Which basically adds some ifdefs to
_Blender3DPlugin_implementation_.cpp
Basically I modified the nan_definitions.mk in the following way
(You'll need to update yours don't forget) ;)
Also updated the makefiles to use the new vars and flushed them out
so they first include whatever nspr is set to and then look in
NAN_MOZILLA_INC
I wasn't sure what the NAN_MOZILLA_INC and _LIB defaults should be
since were assuming they point to a netscape dir by default (or maybe
old mozilla???)
maybe they should be
export NAN_MOZILLA_INC ?= $(LCGDIR)/netscape/include
export NAN_MOZILLA_LIB ?= $(LCGDIR)/netscape/lib/
instead...
Anyone have any opinions on the defaults?
