As usual the header should work with windows (32- and 64-bit), Mac OSX (at least in FPC, haven’t tested with XE2) and Linux (naturally FPC only). Since I’m on an ATI (AMD) GPU and only NVidia has released OpenGL 4.3 drivers I wasn’t able to test out the new features. Some of the new features are compute shaders (along with shader buffers to feed them with data and to retrieve it from them), new texture compression formats, and some new vendor extensions (like NV_Path for pathrendering, e.g. So if you’re developing cutting-edge 3D stuff with Delphi or Free Pascal you can now use the latest features available, as long as you’ve got the hardware and your vendor released new drivers ( I can’t wait for the first OpenGL 4.3 report to be uploaded to the glCapsViewer database Update : Thanks to end, who has uploaded the first OpenGL 4.3 report to the database!).
By using the graphics processor ( GPU) cores to work on inherently parallel tasks, developers have a shot at adding great effects without killing the application’s performance.Just a quick heads-up to let you know that I’ve updated our “official” OpenGL-Headers for Delphi / Free Pascal to the recently release version of OpenGL 4.3.
There are many more API changes, but Compute Shaders are most likely the most important update for OpenGL 4.3. OpenCL is another way to perform such operations, and although Compute Shader are more limited than OpenGL, they integrate much better within a graphics application and can be called upon at a much higher frequency. While the compute shaders are limited to the instruction available within an OpenGL shader (in the GLSL language), it is complex enough to perform complex physics computations and leave the results available for OpenGL to use in a graphic operation right away. This is a simpler way for programmers to process general data using the graphics processor cores. The most important feature of OpenGL 4.3 is the introduction of Compute Shaders. With this latest release, OpenGL catches up to features that were only available to DirectX 11, namely Compute Shaders. The variant for mobile devices is called OpenGL ES and just got bumped to 3.0. The Khronos group has released the specifications for OpenGL 4.3, the graphics API (Application Programming Interface) for personal computers and workstations.
