OpenGL 4.1

The Khronos™ Group announced the release of the OpenGL® 4.1 specification at SIGGRAPH 2010.

New functionality in the core OpenGL 4.1 specification includes:

  • Full compatibility with OpenGL ES 2.0 APIs for easier porting between mobile and desktop platforms;
  • The ability to query and load a binary for shader program objects to save re-compilation time;
  • The capability to bind programs individually to programmable stages for programming flexibility;
  • 64-bit floating-point component vertex shader inputs for higher geometric precision;
  • Multiple viewports for a rendering surface for increased rendering flexibility.

New ARB extensions introduced with OpenGL 4.1 include:

  • OpenGL sync objects linked to OpenCL event objects for enhanced OpenCL interoperability;
  • The ability to set stencil values in a fragment shader for enhanced rendering flexibility;
  • Features to improve robustness, for example when running WebGL applications;
  • Callback mechanisms to receive enhanced errors and warning messages.
