Questions tagged [opengl-es-3.1]

OpenGL ES is a subset of the OpenGL 3D graphics API designed for embedded devices such as mobile phones and tablets. Version 3.1 follows version 3.0, and is backwards compatible to versions 3.0 and 2.0. The specification was publicly released on March 17, 2014.

OpenGL ES 3.1 is the follow-up version to OpenGL ES 3.0. Key new features relative to 3.0 include:

  • Compute shaders.
  • Separate shader objects.
  • Indirect draw commands.
  • Multisample textures.
  • Stencil textures.
  • New arithmetic and bitfield operations in shader code.
