svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD

Notes:
* Game and sequencer RNA, and sequencer header are now out of date
  a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
  not needed anymore.
  * Fix "duplicate strip" always increase the user count for ipo.
  * IPO pinning on sequencer strips was lost during Undo.

a1bef84ea8 Allow Bullet soft bodies to be created using a AddObject actuator. Added a fake world coordinate system to game soft bodies, although the vertices are already in world space.
Added Bullet/Gimpact concave collision detection to Blender. If your build system isn't updated yet, please add extern/bullet2/src/BulletCollision/Gimpact/*
This allows moving/dynamic concave triangle meshes (decomposing meshes into compound convex shapes, and using 'compound' shapes is still preferred)

9064ed8d6a Fix for bug #4192: game engine armatures that are dynamically added
but don't have an action got the pose of already added armatures, even
though they're not related. This also fixes an issue where the armature
in Blender would end up in the pose from the game after ESC, removes
unneeded copies made during armature evaluation, and also solves the
constraint copying hack.

cb89decfdc Merge of first part of changes from the apricot branch, especially
the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:

* GLSL support in the viewport and game engine, enable in the game
  menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
  gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
  storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.

* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
  An extra texture slot shows up once the last slot is used.

* Memory limit for undo, not enabled by default yet because it
  needs the .B.blend to be changed.
* Multiple undo for image painting.

* An offset for dupligroups, so not all objects in a group have to
  be at the origin.

99fdf27af9 Sync with Apricot Game Engine
=============================

* Clean up and optimizations in skinned/deformed mesh code.
* Compatibility fixes and clean up in the rasterizer.
* Changes related to GLSL shadow buffers which should have no
  effect, to keep the code in sync with apricot.

820c2df12c BGE patch: Add automatic support for armature driven shape keys.
To take advantage of this feature, you must have a mesh with 
relative shape keys and shape Ipo curves with drivers referring
to bones of the mesh's parent armature. 
The BGE will automatically detect the dependency between the 
shape keys and the armature and execute the Ipo drivers during
the rendering of the armature actions.
This technique is used to make the armature action more natural: 
the shape keys compensate in places where the armature deformation 
is uggly and the drivers make sure that the shape correction
is synchronized with the bone position.

Note: This is not compatible with shape actions; BLender does 
not allow to have Shape Ipo Curves and Shape actions at the same
time.

2bece8dcb5 BGE Patch: Add Shape Action support and update MSCV_7 project file for glew.
Shape Action are now supported in the BGE. A new type of actuator "Shape Action" is available on mesh objects. It can be combined with Action actuator on parent armature. Only relative keys are supported. All the usual action options are available: type, blending, priority, Python API. Only actions with shape channels should be specified of course, otherwise the actuator has no effect. Shape action will still work after a mesh replacement provided that the new mesh has compatible shape keys.

272a91f754 Merge of apricot branch game engine changes into trunk, excluding GLSL.
GLEW
====

Added the GLEW opengl extension library into extern/, always compiled
into Blender now. This is much nicer than doing this kind of extension
management manually, and will be used in the game engine, for GLSL, and
other opengl extensions.

* According to the GLEW website it works on Windows, Linux, Mac OS X,
  FreeBSD, Irix, and Solaris. There might still be platform specific
  issues due to this commit, so let me know and I'll look into it.
* This means also that all extensions will now always be compiled in,
  regardless of the glext.h on the platform where compilation happens.

Game Engine
===========

Refactoring of the use of opengl extensions and other drawing code
in the game engine, and cleaning up some hacks related to GLSL
integration. These changes will be merged into trunk too after this.

The game engine graphics demos & apricot level survived my tests,
but this could use some good testing of course.

For users: please test with the options "Generate Display Lists" and
"Vertex Arrays" enabled, these should be the fastest and are supposed
to be "unreliable", but if that's the case that's probably due to bugs
that can be fixed.

* The game engine now also uses GLEW for extensions, replacing the
  custom opengl extensions code that was there. Removes a lot of
  #ifdef's, but the runtime checks stay of course.
* Removed the WITHOUT_GLEXT environment variable. This was added to
  work around a specific bug and only disabled multitexturing anyway.
  It might also have caused a slowdown since it was retrieving the
  environment variable for every vertex in immediate mode (bug #13680).

* Refactored the code to allow drawing skinned meshes with vertex
  arrays too, removing some specific immediate mode drawing functions
  for this that only did extra normal calculation. Now it always splits
  vertices of flat faces instead.
* Refactored normal recalculation with some minor optimizations,
  required for the above change.
* Removed some outdated code behind the __NLA_OLDDEFORM #ifdef.
* Fixed various bugs in setting of multitexture coordinates and vertex
  attributes for vertex arrays. These were not being enabled/disabled
  correct according to the opengl spec, leading to crashes. Also tangent
  attributes used an immediate mode call for vertex arrays, which can't
  work.
* Fixed use of uninitialized variable in RAS_TexVert.
* Exporting skinned meshes was doing O(n^2) lookups for vertices and
  deform weights, now uses same trick as regular meshes.

cc33fcfe7b Commit patch #2439: Mesh replacement in BGE will react properly to armature deform
Changing the mesh of an object that has a deform controller (armature) is now properly handled. The new mesh must have vertex groups matching the armature bones. In simple terms, the new mesh must deform correctly when you assign it to the object in Blender and you test the action. It will deform the same when you replace the object mesh during the game.

12a732fc20 Added a VGroup input to the Armature modifier. This allows the user to specify
a vertex group which will modulate the influence of all bones in the armature.

This commit also tidies up the height of the modifier panels; they should all
have the same size margin now.

433f6c7043 Integration of the Google Summer of Code Modifier Stack Upgrade project. The
main features are:
* Modifiers can now be in any order in the modifier stack
* DerivedMesh now has a standard framework for custom element data to be passed
  through the stack with mesh data (being copied and interpolated as
  appropriate), so modifiers can access whatever data they need
* The modifier stack code has been refactored and a number of bugs have been
  removed
* The EdgeSplit modifier has been added:
  http://mediawiki.blender.org/index.php/BlenderDev/EdgeSplitModifier
* The DerivedMesh modifier has been added:
  http://mediawiki.blender.org/index.php/BlenderDev/DisplaceModifier
* The UVProject modifier has been added:
  http://mediawiki.blender.org/index.php/BlenderDev/UVProjectModifier

be282bdf3f - Charlie fixed some bugs related to copying armature-constraint data (these are different from Bullet rigidbody constraints like the hinge, and point 2 point!)
- fixed a crashing bug related to objects without meshes (tried to get material info from it)

2e6d576182 Sorry to break the cvs-closed status, so if you really need to make a new 2.40 build, just disable the game engine if it doesn't compile for a platform. Again, sorry if this breaks non-windows platforms, but I hope people help to get this amazing fix working for all platforms. Armature-fixing contribution from Snailrose. Also lots of cool things from Snailrose and Lagan.
Armatures are back
Split screen
Double sided lightning
Ambient lighting
Alpha test
Material IPO support (one per object atm)
Blender materials
GLSL shaders - Python access
Up to three texture samplers from the material panel ( 2D & Cube map )
Python access to a second set of uv coordinates

9119b6e8a5 Fixed several bugs: python refcounting related and Bullet related (basic add/remove object support, bounding volume hierarchy). Added a few files, updated the Bullet scons. Vc6/7 Bullet projectfiles need to add a couple of files: 'Bullet/CollisionShapes/BvhTriangleMeshShape.cpp',
'Bullet/CollisionShapes/ConvexTriangleCallback.cpp',
'Bullet/CollisionShapes/EmptyShape.cpp',
'Bullet/CollisionShapes/OptimizedBvh.cpp',
'Bullet/CollisionShapes/TriangleCallback.cpp',
'Bullet/CollisionShapes/TriangleIndexVertexArray.cpp',
'Bullet/NarrowPhaseCollision/ManifoldContactAddResult.cpp'.
Sorry, no armatures fix yet.

0140c36df9 Cleanup & preparation commit for getting Armatures/Poses/Actions working
in the game engine again.

All files in source/gameengine/ I've committed below have a comment like
/* XXX note .... */
where something needs to be done. This is pretty straightforward for Erwin,
who has been notified in person too about this. :)

841ddb4680 A couple of small fixes...
I removed config.h code from the files that had them.
effect.c had nested /* so cleaned that up...

added a newline to vector.c to shut gcc up ;)
buttons_editing.c had a possible unintalized var (height) so I gave
it a default value.

removed an unused var i in interface_draw.c
removed an unused var mti in outliner.c

in BL_SkinDeformer.cpp
commented out a call to bDeformGroup->data which no longer exists so it
compiles again.

28a1e8277b Result of 2 weeks of quiet coding work in Greece :)
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

00291b5cf4 [GameEngine] Commit all Kester's changes made to the gameengine to restore 2.25 like physics.
[SCons] Build with Solid as default when enabling the gameengine in the build process
[SCons] Build solid and qhull from the extern directory and link statically against them

That was about it.

There are a few things that needs double checking:

* Makefiles
* Projectfiles
* All the other systems than Linux and Windows on which the build (with scons) has been successfully tested.

aedf456938 - split the data structures that actually constitute a mesh
(MVert,MFace,etc) off into DNA_meshdata_types.h, to isolate areas
    of source that actually edit mesh *data* vs. areas that just edit
    mesh object information.
