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* Removed some outdated code behind the __NLA_OLDDEFORM #ifdef.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.

8bd82d4e36 Some pose action ipo corruptions when using BGE, added some debug printf's when copying to/from the same pose since it should never happen. 2008-06-13 02:20:09 +00:00

5d0a207ecb Patch from GSR that a) fixes a whole bunch of GPL/BL license
blocks that were previously missed; and b) greatly increase my
ohloh stats!

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

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. :)

24c9dc7322 Commented out one more line to make debug version of engine compile, needed
because API for armatures changed.

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
