Khronos Group publishes OpenGL 4.0 specs:

• OpenGL 4.0 is a royalty-free cross-platform standard.
• This was presented at the Game Developers Conference in San Francisco (March 2010).
• This OpenGL version is faster and more efficient than previous iterations.
• Included are 2 new shader stages - advantage of enabling the GPU to offload geometry tessellation from the CPU.
• There is also inclusion of 64-bit double precision floating point shader operations.
• Other performance enhancements include instanced geometry shaders, instanced arrays & also a new timer query.
• This new standard will also help produce improvements to OpenGL ES.
• Note - OpenGL ES is the graphics system used in the majority of smartphones & should help with developing the introduction of smartphone 3D interfaces.
• Interestingly - the company AMD contributes to the Khronos workgroups.
