OpenGL The Industry's Foundation for High Performance Graphics

OpenGL® is the most widely adopted 2D and 3D graphics API in the industry, bringing thousands of applications to a wide variety of computer platforms. It is window-system and operating-system independent as well as network-transparent. OpenGL enables developers of software for PC, workstation, and supercomputing hardware to create high-performance, visually compelling graphics software applications, in markets such as CAD, content creation, energy, entertainment, game development, manufacturing, medical, and virtual reality. OpenGL exposes all the features of the latest graphics hardware.

OpenGL 4.5 at a glance

The OpenGL 4.5 and OpenGL Shading Language 4.50 Specifications were released on August 11, 2014.

New features of OpenGL 4.5 include:

  • Direct State Access (DSA)
    object accessors enable state to be queried and modified without binding objects to contexts, for increased application and middleware efficiency and flexibility;
  • Flush Control
    applications can control flushing of pending commands before context switching – enabling high-performance multithreaded applications;
  • Robustness
    providing a secure platform for applications such as WebGL browsers, including preventing a GPU reset affecting any other running applications;
  • OpenGL ES 3.1 API and shader compatibility
    to enable the easy development and execution of the latest OpenGL ES applications on desktop systems;
  • DX11 emulation features
    for easier porting of applications between OpenGL and Direct3D.

New extensions to OpenGL 4.5 include:

  • GL_ARB_clip_control
  • GL_ARB_cull_distance
  • GL_ARB_ES3_1_compatibility
  • GL_ARB_conditional_render_inverted
  • GL_KHR_context_flush_control
  • GL_ARB_derivative_control
  • GL_ARB_direct_state_access
  • GL_ARB_get_texture_sub_image
  • GL_KHR_robustness
  • GL_ARB_shader_texture_image_samples
  • GL_ARB_texture_barrier
