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.

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.

BGE: Committing a patch from HG1 to fix [#30262] "bgl.glClipPlane don't work on Nvidia cards," which was also reported by HG1.

// Setting gl_ClipVertex is necessary to get glClipPlane working on NVIDIA graphic cards.
// gl_ClipVertex works only on NVIDIA graphic cards so we have to check with
// __GLSL_CG_DATA_TYPES if a NVIDIA graphic card is used (Cg support).
// gl_ClipVerte is supported up to GLSL 1.20.
