Temporarily disabled game engine for scons and Makefiles (nan_definitions?), this to upgrade to Bullet 2.x
scons for Darwin, Linux, BSD3, SunOS5, Win32, and Makefiles should not compile game engine right now.
CMake and MSVC needs still disabling of game engine.
Everyone else was using gzip. On the latest downloads many of them
are using bzip2, (I think everyone using scons)
So I decided to update make release so that everyone is using
gzip2. I don't mean to step on anyones toes, I know at least some of
the platform maintainers do not use make though so feel free to change
it back and or to something different for your platform.
While I was at it I also changed default path of OPENEXR to /usr on linux.
Was suggested on mailing list by Matt.
(I'm pretty sure the linux maintainer is using scons)

- Added a new Brush datablock, only used by image paint, but intended
to be used in texture paint, vertex paint, weight paint and sculpt
mode also.
- Being a datablock, these brushes can be saved, appended and linked.
They have a fake user by default, to make sure they are saved even if
not selected.
Image Painting:
- Replaced the img module with C code in imagepaint.c
- Airbrush is no longer a separate tool, but rather an option that can
be used for soften, smear and clone also.
- Blend modes mix, add, subtract, multiply, darken and lighten have been
added, code taken directly from vertex paint.
Note to project files maintainers:
- The img module was removed from SCons and Makefiles, and this should
be done in other build systems also. I'll wait to remove the module
from cvs, to not break compilation.
- patch from Douglas with endian fixes
- Makefile adds static libiconv.a from lib/
- this version will use OpenEXR libs from lib/ too, and is latest release
with threading support
- openAL is missing, added it as default to not include it
Made internal ffmpeg-libraries link by explicitly specifying the archive-files.
(Thanks GSR for pointing this out)
Otherwise, blender always links to the system-libs.
If "export NAN_USE_FFMPEG_CONFIG=true" is added to user-def.mk,
the system executes the ffmeg-config program to set values
for NAN_FFMPEG (--prefix), NAN_FFMPEGLIBS (--libs avcodec avformat),
and NAN_FFMPEGCFLAGS (--cflags). Only one used so far is the
NAN_FFMPEGLIBS for linking on linux (if requested to do so).
Current default is not to do this.
always statically (you have to force it to build a dynamic library) the
resulting binary is redistributable.
The code is made ffmpeg-version independent using #ifdef's.
Here are my notes on things to look out for as potential problem
spots:
source/blender/blenkernel/intern/displist.c:
+ is initfastshade(void) supposed to be empty? I had
to make it empty to get the merged tree to compile.
source/blender/python/api2_2x/Armature.c:
+ went with the version that had Armature_getLayers()
source/blender/python/api2_2x/Object.c
+ went with the version of Object_getPose() from bf-blender.
(#ifdef 0-ed the other version)
source/blender/python/api2_2x/Pose.[ch]
+ had problems linking due to no Pose_Init() ... copied these
two files straight from bf-blender.
source/blender/src/drawview.c:
+ view3d_panel_properties() had things shifted a few things shifted
a few pixels, otherwise, things were painless
source/blender/src/splash.jpg.c:
+ went with bf-blender version (orange is dead)
source/gameengine:
+ went with bf-blender version -- does not compile due to IMB_rect* stuff,
Ton should look into this.
(with make, need to confirm with scons)
after cleaning the changes are in fact minimal, but the situation
is still quite a bit hackish.
Game engine coders, there is also quite a number of warnings that
need to be fixed.
current situation is that everything seems to work, but GLSL shaders
spew a lot of errors on console and blender may crash on exit when
a GLSL shader was used. ARB stuff works fine.
some strange merging). Unfortunately, Bullet doesn't build correctly
for gcc under cygwin (some private vs public stuff), so it is
important to be able to disable the game engine in these circumstances.
These should make it so that other people can compile with OpenEXR support.
(I also added the OPENAL fix erwin commited to bf-blender since I
need it for my machine, and this syncs up the file)

To enable dynamic tiff support.
I had to fix some of the logic in the fileselect box for icons,
I also expanded the patch to look in various default locations for
a dynamic libtiff.so/libtiff.dll
and look at the env variable BF_TIFF_LIB if it can't find it automatically.
If unable to load the library it prints a message about setting BF_TIFF_LIB
to the console.
I haven't been able to test it on a lot of platforms but hopefully it
will just work ;) I added the files to scons but have not had a chance to
test that as well.

so there will be more files following.
Anyway: NEW BOOLEANS from Google Summer of Code (Courtesy of Marc Freixas)
Known problems:
- Random freezes while using them as a modifier. This may not be directly
related to modifiers though - it's maybe just the huge number of
operations that leads to a higher probability of triggering a bug
- Static booleans (the first 3 entries in the WKEY menu) are borked
anyway, this is not due to this commit.
- Errors when exiting Blender (dupli_alloc stuff), is not related to this
commit, either.
Please test if everything works, and check the other build systems, I only
know that make works.
Also, compare the results of, say, cube-cylinder, in old and new booleans
:)
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).
