Vladimír Vondruš	5998f46e12	Added support for glMultiDrawArrays()/glMultiDrawElements(). In OpenGL ES this is implemented in EXT_multi_draw_arrays extension, if it is not available, the functionality is emulated using sequence of normal draw() calls.	12 years ago
Vladimír Vondruš	4e50aeee31	Ability to reset internal state tracker.	12 years ago
Vladimír Vondruš	71a5766594	Added Mesh::addVertexBufferInstanced(). Functionality provided by GL 3.3 and ARB_instanced_arrays, on ES2 this is again implemented in three different extensions -- {ANGLE,EXT,NV}_instanced_arrays. They are disabled until Magnum has proper extension loading on ES.	12 years ago
Vladimír Vondruš	20df20de0f	Support for instanced mesh drawing and base instance. On desktop GL this is provided by ARB_draw_instanced (GL 3.1). Base instance is available only on desktop GL (4.2, ARB_base_instance). In ES2 the instanced functionality is provided by three (!) different extensions (ANGLE_instanced_arrays, EXT_draw_instanced, NV_draw_instanced), the proper implementation is chosen on context creation based on what extension is available. Though we don't have extension loader for ES yet, thus all these extensions are disabled and the implementation has assertion in it. Added blind test which tests only that something has been drawn and no errors were emitted, but not whether the right command is used. I'll probably need to check this later, because the Mesh::draw() behemoth is going slightly out of hand :)	12 years ago
Vladimír Vondruš	1ad8be425f	Moved global data from Mesh class to per-context state.	12 years ago
