Retired Document Important: OpenGL was deprecated in macOS 10.14. To create high-performance code on GPUs, use the Metal framework instead. 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.
Gl Arb Framebuffer Object Drivers For Mac Os
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 GLARBtextureenvcombine or GLEXTtextureenvcombine 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. Note: It's possible for vendor and ARB extensions to provide similar functionality. As particular functionality becomes widely adopted, it can be moved into the core OpenGL API. As a result, functionality that you want to use could be included as an extension, as part of the core API, or both. You should read the extensions and the core OpenGL specifications carefully to see the differences.
Furthermore, as an extension is promoted, the API associated with that functionality can change. For more information, see. 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.
Qt Opengl Framebuffer
This release only fixes a build error in the radeonsi driver that was introduced. This is a step toward hardware support for the OpenGL 2.0 Shading Language. Divides s,t,r by q - ARB frag prog TEX and TEXP instructions now use LOD=0. Updated GL/glext.h file to version 21 Changes: - changed max framebuffer size to. An API is a set of functions, classes, and tokens used to define a particular set of software tools. OpenGL is an API for graphics. ARB See OpenGL Architecture.
