Retired Document

Important: OpenGL was deprecated in macOS 10.14. To create high-performance code on GPUs, use the Metal framework instead. See Metal.

Legacy OpenGL Functionality by Version

OpenGL functionality changes with each version of the OpenGL API. This appendix describes the functionality that was added with each version. See the official OpenGL specification for detailed information.

The functionality for each version is guaranteed to be available through the OpenGL API even if a particular renderer does not support all of the extensions in a version. For example, a renderer that claims to support OpenGL 1.3 might not export the GL_ARB_texture_env_combine or GL_EXT_texture_env_combine extensions. It's important that you query both the renderer version and extension string to make sure that the renderer supports any functionality that you want to use.

In the following tables, the extensions describe the feature that the core functionality is based on. The core functionality might not be the same as the extension. For example, compare the core texture crossbar functionality with the extension that it's based on.

Version 1.1

**Table A-1** Functionality added in OpenGL 1.1
