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 * Removed some outdated code behind the __NLA_OLDDEFORM #ifdef.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

TexFace to Material Settings big patch Summary: ======== The idea here is to move the texface options into the material panel. For images with the change please visit: http://code.blender.org/index.php/2011/09/bge-material-texface-changes 1 - Some of the legacy problems 2.49 and 2.5x has with the texface system: ========================================================================== 1.1) Shadow, Bilboard and Halo are mutual exclusive (in the code), yet you can select a face to be more than one mode. 1.2) Sort only works for blend Alpha yet it's an option regardless of the Transparency Blend you pick. 1.3) Shared doesn't affect anything in BGE. 1.4) ObColor only works for Text objects (old bitmap texts) when using Texture Face Materials. (not address yet, I so far ignored obcolor) 2 - Notes: ============ 2.1) Now "Use Face Textures" in material Option panel will work in Multitexture even if there is no texture channel. 2.2) In FaceTexture mode it will use TexFace all the time, even if you don't check the "Use Texture Face" option in the UI. It's a matter of decision, since the code for either way is there. I decided by the solution that makes the creation of a material fast - in this mode the user doesn't need to mess with textures or this "Use Texture Face" option at all. I'm not strong in my opinion here. But I think if we don't have this then what is the point of the Texture Face mode? 2.3) I kept references for tface only when we need the image, UV or the tiling setting. It should help later when/if we split the Image and UV layers from the tface struct (Campbell and Brecht proposal). 3 - Changes in a Nutshell: ========================== 3.1) "Texture Face" panel (in the Mesh/Object Data panel) no longer exists. Those settings are all part of the material properties, visible when Game Render is set. 3.2) "Texture Face" Shading mode (in the Render panel) is now called “Single Texture”, it needs a material for special settings (e.g. Billboard, Alpha Sort, …). 3.3) New options in the Material Panel * Shadeless option in the Material panel is now supported for all three Shading modes. * Physics is now toggleable, this is the old Collision option. * Two Side (on) is now called Back Culling (off). * Alpha Sort is one of the Alpha options, together (and mutually exclusive) to Alpha Blend, Alpha Clip, Add and Opaque (i.e. solid). * Shadow, Billboard and Halo are grouped in the “Face Orientation” property. * "Face Textures" and "Face Textures Alpha" (under Options) can be used for all but GLSL shading mode (to be supported in GLSL eventually). * The backend in the game engine is still the same as before. The only changes are in the interface and in the way you need to think your materials. The bottomline is: It’s no longer possible to share materials between faces that do not share the same game properties. 4 - Acknowledgment: ================== Mike Pan for the design discussions, and testing along the whole development process. Vitor Balbio for the first hands-on code with the interface changes. That helped me a lot to push me into work on that. Benoit Bolsee and Brecht van Lommel for patch review (* no one reviewed the whole patch, or the latest iteractions, so I still hold liability for any problems). Blender artists that gave feedback and helped testing the patch.
