a3e296fc40 Committing patch #25676 Anisotropic filtering in viewport and BGE by me.
This patch adds anisotropic filtering of textures in the viewport and the BGE. The quality of the filtering is adjustable in the user preferences under System. For more information on anisotropic filtering:
http://en.wikipedia.org/wiki/Anisotropic_filtering

One current limitation of this setup (having the option a user preference) is it makes runtimes more troublesome. Runtimes don't have user preferences set, so for now the blender player defaults to 2x AF. Options will be added later to change this value (probably a command line option).

32eba0898b Reverting revision 33120, which added vram monitoring. The method used had some problems (especially in the freeing function). I will research an alternative solution and submit it to the tracker. 2010-11-24 06:27:07 +00:00

1bb98b4194 Adding monitoring for (approximate) VRAM used by textures. The information is currently only used in the profiling data of the BGE.
Here is a image of it in action:
http://www.pasteall.org/pic/show.php?id=6351

What it monitors:
  * VRAM used by textures created via bf_gpu and BL_Textures

What it does not monitor:
  * VRAM used by the Blender ui
  * VRAM used by 2d filters
  * VRAM allocated by the user via KX_Scene.pre_draw and KX_Scene.pre_draw

8268a4be71 most unused arg warnings corrected.
- removed deprecated bitmap arg from IMB_allocImBuf (plugins will need updating).
- mostly tagged UNUSED() since some of these functions look like they may need to have the arguments used later.

cdec2b3d15 BGE Python API
Use 'const char *' rather then the C++ 'STR_String' type for the attribute identifier of python attributes.

Each attribute and method access from python was allocating and freeing the string.
A simple test with getting an attribute a loop shows this speeds up attribute lookups a bit over 2x.

908337bee1 Game Engine: alpha blending and sorting
=======================================

Alpha blending + sorting was revised, to fix bugs and get it
to work more predictable.

* A new per texture face "Sort" setting defines if the face
  is alpha sorted or not, instead of abusing the "ZTransp"
  setting as it did before.
* Existing files are converted to hopefully match the old
  behavior as much as possible with a version patch.
* On new meshes the Sort flag is disabled by the default, to
  avoid unexpected and hard to find slowdowns.
* Alpha sorting for faces was incredibly slow. Sorting faces
  in a mesh with 600 faces lowered the framerate from 200 to
  70 fps in my test.. the sorting there case goes about 15x
  faster now, but it is still advised to use Clip Alpha if
  possible instead of regular Alpha.
* There still various limitations in the alpha sorting code,
  I've added some comments to the code about this.

Some docs at the bottom of the page:
http://www.blender.org/development/current-projects/changes-since-246/realtime-glsl-materials/

Merged some fixes from the apricot branch, most important
change is that  tangents are now exactly the same as the rest
of Blender, instead of being computed in the game engine with a
different algorithm.

Also, the subversion was bumped to 1.

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.

867e12836b This patch spawns from this game engine issue:
[#7113] GE crash pressing as soon as P on 64 bit


Note:         glext.h has been removed from the source
        If you get errors compiling with it you have 2 options
                download/install 	glext.h        (preferred method)
                or set WITH_BF_GLEXT=false
        If your a user and having problems with game engine try
                setting the env var: WITHOUT_GLEXT 1

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.

3947f9b885 1). Fix for cube maps in the player.
ImBuf pointer was being overridden causing the ibuf->rect to be zero.

2). Added vertex attributes for tangents in in vertex arrays.
This, probably needs the extensions enabled (glEnableVertexAttribArrayARB, glDisableVertexAttribArrayARB), but am a little
weary about enabling them right now.

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.
