A new release of the OpenGL Samples Pack with OpenGL 4.0 samples is on its way!
Currently, the new pack contains 8 OpenGL 4.0 samples including tessellation, geometry instancing, texture fetch (trilinear filtering), texture gather, transform feedback object, MRT blend state, draw indirect and subroutine.
Next to these samples I choose to add all the OpenGL 3.3 (including new onces: geometry shaders, texture fetch, blend index and MRT blend) and all the OpenGL 2.1 samples for a total of 55 samples so far.
The only trouble in the picture... I still didn't manage to get it working on MacOS X with CMake. :/
