A Lighthouse3D short tutorial on OpenGL atomic buffers is now available in here. The tutorial covers both the OpenGL and GLSL definition and usage. As the official documentation, and demos on the net are not abundant, it is difficult to be too assertive in some issues. Everything on the tutorial has been tested and it works perfectly with recent NVIDIA beta drivers. Unfortunately, a few things seem not to work with AMD catalyst 12.9 drivers. Anyway, check it out, and let me know if I missed something, or if you find any bugs.
