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* Removed some outdated code behind the __NLA_OLDDEFORM #ifdef.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

f63b70635c bugfix, clip alpha wasn't working in the GE, not happy with these functions, they probably need bigger changes not to assume all alpha requires face sorting with a disabled depth buffer, 2008-06-15 09:43:24 +00:00

cf654b44b6 Fix BGE bug in patch #8724 (memory optimization): serious problem with alpha texture when Use Blender Material is active and several objects have same texture. This bug messes up greatly with OpenGL texture. The GE is not usable without this fix. 2008-05-04 21:14:38 +00:00

b73ba9c181 This commit reverts the #include <mesa/glu.h>
stuff used for peach to the standard <GL/glu.h>
the mesa stuff was needed for the machines for peach but its
not the stanard location of the headers, now that its not
needed were switching it back.

7b2e348d4f This is a modified version of this patch:
[#7660] Solaris 10 x86 support (Makefiles)

Hopefully it will not mess up anything for anyone else.  I removed
some hardcoded static libs and made NAN_*_LIB definitions so they could be 
overridden, to allow greater flexability.

Let me know if there are any problems/questions.

c4202fbd43 First commit! Small bug fix for cube map crashing in the player.
Cube maps don't display correctly in the player at the moment too.. something to do with regenerating/loading the images

4a70681ce2 patch by Charlie, related to recent changes of multi-uv/lightmap generation. This fix makes it possible to use lightmaps in the game engine. 2007-01-07 04:39:39 +00:00

e435fbc3c5 Added custom vertex/edge/face data for meshes:
All data layers, including MVert/MEdge/MFace, are now managed as custom
data layers. The pointers like Mesh.mvert, Mesh.dvert or Mesh.mcol are
still used of course, but allocating, copying or freeing these arrays
should be done through the CustomData API.

Work in progress documentation on this is here:
http://mediawiki.blender.org/index.php/BlenderDev/BlenderArchitecture/CustomData


Replaced TFace by MTFace:

This is the same struct, except that it does not contain color, that now
always stays separated in MCol. This was not a good design decision to
begin with, and it is needed for adding multiple color layers later. Note
that this does mean older Blender versions will not be able to read UV
coordinates from the next release, due to an SDNA limitation.


Removed DispListMesh:

This now fully replaced by DerivedMesh. To provide access to arrays of
vertices, edges and faces, like DispListMesh does. The semantics of the
DerivedMesh.getVertArray() and similar functions were changed to return
a pointer to an array if one exists, or otherwise allocate a temporary
one. On releasing the DerivedMesh, this temporary array will be removed
automatically.


Removed ssDM and meshDM DerivedMesh backends:

The ssDM backend was for DispListMesh, so that became obsolete automatically.
The meshDM backend was replaced by the custom data backend, that now figures
out which layers need to be modified, and only duplicates those.


This changes code in many places, and overall removes 2514 lines of code.
So, there's a good chance this might break some stuff, although I've been
testing it for a few days now. The good news is, adding multiple color and
uv layers should now become easy.

85c58bfa8a attempt to fix reported problems with glsl shader on OS X (and other platforms). instead of continuous printing errors, it should just print once, and delete the shaders.
also, disabled the asynchronous logicbrick update, it reportedly causes jitter.

77c4eef90b after much suffering, got GE build and work almost cleanly on Os X
(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.

0002cd63a5 disable game engine and gameplayer for all platforms except windows.
Then after cvs is unfrozen, development can continue.

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
