Raw Normal View History

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.

Another attempt for T40981, clipping border does not work with GLSL on ATIs. This is actually a test to see if this can be enabled on ATI cards. According to various sources, newer ATI cards supporting GLSL 3.0 support gl_ClippingDistance in shaders, which is the forward compatible way to do custom clipping. This fix will bind 6 additional varying variables on ATIs, which may lead to some shaders not compiling due to limiting out of those variables, or to performance degradation. Also I do not have an ATI handy to test. Having those in mind, this commit may well be reverted later. Clipping planes are usually 4 (6 is for cube clipping), but making shaders depend on viewport state is really bad, and would lead to recompilation, so I took the worst case here to avoid that. Hopefully driver does some optimization there.

This commit will switch blender to use tangent space generated within the two files mikktspace.h and mikktspace.c. These are standalone files which can be redistributed into any other application and regenerate the same tangent spaces. The implementation is independent of the ordering of faces and the vertex ordering of faces.

Disable clipping on ATI cards not supporting the clipping workaround to avoid software fallback.

// Setting gl_ClipVertex is necessary to get glClipPlane working on NVIDIA
// graphic cards, while on ATI it can cause a software fallback.

OpenGL: implemenation of fixed function lighting as per pixel GLSL shaders. The code is still unused, but the intention is to use this to solve the double sided lighting problem on NVidia, and to make the materials work on OpenGL ES 2.0 eventually. The code works and matches the fixed function lighting pretty much exactly, but still needs optimizations. The actual integration in object draw will be committed later when more fixing & testing, there's lots of different combinations and unclear OpenGL state here.

Revert "Add missing trailing '}' in GLSL files" This reverts commit ebd4a6e0dd3bdd511f3857dc9192df848f388200. Trailing '}' is added in C, also we add some extra code as needed.
