At a Glance
OpenGL is an excellent choice for graphics development on the Macintosh platform because it offers the following advantages:
- Reliable Implementation. The OpenGL client-server model abstracts hardware details and guarantees consistent presentation on any compliant hardware and software configuration. Every implementation of OpenGL adheres to the OpenGL specification and must pass a set of conformance tests.
- Performance. Applications can harness the considerable power of the graphics hardware to improve rendering speeds and quality.
- Industry acceptance. The specification for OpenGL is controlled by the Khronos Group, an industry consortium whose members include many of the major companies in the computer graphics industry, including Apple. In addition to OpenGL for OS X, there are OpenGL implementations for Windows, Linux, Irix, Solaris, and many game consoles.
OpenGL Is a C-based, Platform-Neutral API
Because OpenGL is a C-based API, it is extremely portable and widely supported. As a C API, it integrates seamlessly with Objective-C based Cocoa applications. OpenGL provides functions your application uses to generate 2D or 3D images. Your application presents the rendered images to the screen or copies them back to its own memory.
The OpenGL specification does not provide a windowing layer of its own. It relies on functions defined by OS X to integrate OpenGL drawing with the windowing system. Your application creates an OS X OpenGL rendering context and attaches a rendering target to it (known as a drawable object). The rendering context manages OpenGL state changes and objects created by calls to the OpenGL API. The drawable object is the final destination for OpenGL drawing commands and is typically associated with a Cocoa window or view.
Different Rendering Destinations Require Different Setup Commands
Depending on whether your application intends to draw OpenGL content to a window, to draw to the entire screen, or to perform offscreen image processing, it takes different steps to create the rendering context and associate it with a drawable object.

OpenGL on Macs Exists in a Heterogenous Environment
Macs support different types of graphics processors, each with different rendering capabilities, supporting versions of OpenGL from 1.x through OpenGL 3.2. When creating a rendering context, your application can accept a broad range of renderers or it can restrict itself to devices with specific capabilities. Once you have a context, you can configure how that context executes OpenGL commands.
OpenGL on the Mac is not only a heterogenous environment, but it is also a dynamic environment. Users can add or remove displays, or take a laptop running on battery power and plug it into a wall. When the graphics environment on the Mac changes, the renderer associated with the context may change. Your application must handle these changes and adjust how it uses OpenGL.

OpenGL Helps Applications Harness the Power of Graphics Processors
Graphics processors are massively parallelized devices optimized for graphics operations. https://pixelpowerful323.weebly.com/blog/android-sdk-download-file-from-server. To access that computing power adds additional overhead because data must move from your application to the GPU over slower internal buses. Accessing the same data simultaneously from both your application and OpenGL is usually restricted. To get great performance in your application, you must carefully design your application to feed data and commands to OpenGL so that the graphics hardware runs in parallel with your application. A poorly tuned application may stall either on the CPU or the GPU waiting for the other to finish processing.
When you are ready to optimize your application’s performance, Apple provides both general-purpose and OpenGL-specific profiling tools that make it easy to learn where your application spends its time.

Concurrency in OpenGL Applications Requires Additional Effort
Many Macs ship with multiple processors or multiple cores, and future hardware is expected to add more of each. Designing applications to take advantage of multiprocessing is critical. OpenGL places additional restrictions on multithreaded applications. If you intend to add concurrency to an OpenGL application, you must ensure that the application does not access the same context from two different threads at the same time.
Performance Tuning Allows Your Application to Provide an Exceptional User Experience
Once you’ve improved the performance of your OpenGL application and taken advantage of concurrency, put some of the freed processing power to work for you. Higher resolution textures, detailed models, and more complex lighting and shading algorithms can improve image quality. Full-scene antialiasing on modern graphics hardware can eliminate many of the “jaggies” common on lower resolution images.

How to Use This Document
If you have never programmed in OpenGL on the Mac, you should read this book in its entirety, starting with OpenGL on the Mac Platform. Critical Mac terminology is defined in that chapter as well as in the Glossary.
If you already have an OpenGL application running on the Mac, but have not yet updated it for OS X v10.7, read Choosing Renderer and Buffer Attributes to learn how to choose an OpenGL profile for your application.
To find out how to update an existing OpenGL app for high resolution, see Optimizing OpenGL for High Resolution.
Once you have OpenGL content in your application, read OpenGL Application Design Strategies to learn fundamental patterns for implementing high-performance OpenGL applications, and the chapters that follow to learn how to apply those patterns to specific OpenGL problems.
Important: Although this guide describes how to create rendering contexts that support OpenGL 3.2, most code examples and discussion in the rest of the book describe the earlier legacy versions of OpenGL. See Updating an Application to Support the OpenGL 3.2 Core Specification for more information on migrating your application to OpenGL 3.2.
Prerequisites
This guide assumes that you have some experience with OpenGL programming, but want to learn how to apply that knowledge to create software for the Mac. Although this guide provides advice on optimizing OpenGL code, it does not provide entry-level information on how to use the OpenGL API. If you are unfamiliar with OpenGL, you should read OpenGL on the Mac Platform to get an overview of OpenGL on the Mac platform, and then read the following OpenGL programming guide and reference documents:

FAQ
Main article: FAQ
This Wiki maintains a FAQ page for OpenGL.
Downloading OpenGL
In all three major desktop platforms (Linux, macOS, and Windows), OpenGL more or less comes with the system. However, you will need to ensure that you have downloaded and installed a recent driver for your graphics hardware.
Windows
Appropriate Windows driver websites:
Some sites also distribute beta versions of graphics drivers, which may give you access to bug fixes or new functionality before an official driver release from the manufacturer:
Without drivers, you will default to a software version of OpenGL 1.1 (on Win98, ME, and 2000), a Direct3D wrapper that supports OpenGL 1.1 (WinXP), or a Direct3D wrapper that supports OpenGL 1.1 (Windows Vista and Windows 7). None of these options are particularly fast, so installing drivers is always a good idea.
If your system does not contain a GPU, or the GPU vendor delivers graphics drivers providing OpenGL support that's so old as to be useless to you, you might want to consider installing the Mesa3D OpenGL library on your system. See this wiki link for details:
Mac Opengl 3.3
Linux
Graphics on Linux is almost exclusively implemented using the X windows system. Supporting OpenGL on Linux involves using GLX extensions to the X Server. There is a standard Application Binary Interface defined for OpenGL on Linux that gives application compatibility for OpenGL for a range of drivers. In addition the Direct Rendering Infrastructure (DRI) is a driver framework that allows drivers to be written and interoperate within a standard framework to easily support hardware acceleration, the DRI is included in of XFree86 4.0 but may need a card specific driver to be configured after installation.These days, XFree86 has been rejected in favor of XOrg due to the change in the license of XFree86, so many developers left Xfree86 and joined the XOrg group. Popular Linux distros come with XOrg now.
Vendors have different approaches to drivers on Linux, some support Open Source efforts using the DRI, and others support closed source frameworks but all methods support the standard ABI that will allow correctly written OpenGL applications to run on Linux.
For more information on developing OpenGL applications on Linux, see Platform specifics: Linux
macOS
Unlike other platforms, where the Operating System and OpenGL implementations are often updated separately, OpenGL updates are included as part of macOS system updates. To obtain the latest OpenGL on macOS, users should upgrade to the latest OS release, which can be found at Apple.com.
Download Opengl For Mac
For developers, a default installation of macOS does not include any OpenGL headers, nor does it include other necessary development tools. These are installed by a separate developer tools package called Xcode. This installer includes the OpenGL headers, compilers (gcc), debuggers (gdb), Apple's Xcode IDE, and a number of performance tools useful for OpenGL application development.
For more information on developing OpenGL applications on macOS, see Platform specifics: macOS.
Writing an OpenGL Application
The first step is to pick your language. Bindings for OpenGL exist in many languages, from C# and Java to Python and Lua. Some languages have multiple sets of OpenGL bindings, none of them being official. All of them are ultimately based on the C/C++ bindings. Secure download manager mac uninstall.
If you are not using C/C++, you must download and install a package or library for your chosen language that includes the OpenGL bindings. Some come pre-installed, but others have separate downloads.
If you are using C/C++, then you must first set up a build environment (Visual Studio project, GNU makefile, CMake file, etc) that can link to OpenGL. Under Windows, you need to statically link to a library called OpenGL32.lib (note that you still link to OpenGL32.lib if you're building a 64-bit executable. The '32' part is meaningless). Visual Studio, and most Windows compilers, come with this library.
On Linux, you need to link to libGL. This is done with a command-line parameter of '-lGL'.
Initialization
Before you can actually use OpenGL in a program, you must first initialize it. Because OpenGL is platform-independent, there is not a standard way to initialize OpenGL; each platform handles it differently. Non-C/C++ language bindings can also handle these differently.
There are two phases of OpenGL initialization. The first phase is the creation of an OpenGL Context; the second phase is to load all of the necessary functions to use OpenGL. Some non-C/C++ language bindings merge these into one.
OpenGL Context Creation
An OpenGL context represents all of OpenGL. Creating one is very platform-specific, as well as language-binding specific.
If you are using the C/C++ language binding for OpenGL, then you are strongly advised to use a window toolkit for managing this task. These libraries create a window, attach an OpenGL context to this window, and manage basic input for that window. Once you are comfortable with OpenGL, you can then start learning how to do this manually.
Most non-C/C++ language bindings will provide you with a language-specific mechanism for creating a context.
Getting Functions
If you are using a non-C/C++ language binding, then the maintainer of that binding will already handle this as part of context creation. If you are using C/C++, read on.
In order to use OpenGL, you must get OpenGL API functions. For most libraries you are familiar with, you simply #include a header file, make sure a library is linked into your project or makefile, and it all works. OpenGL doesn't work that way.
For reasons that are ultimately irrelevant to this discussion, you must manually load functions via a platform-specific API call. This boilerplate work is done with various OpenGL loading libraries; these make this process smooth. You are strongly advised to use one.
If you want to do it manually however, there is a guide as to how to load functions manually. You still should use an extension loader.
Using OpenGL
OpenGL is a rendering library. What OpenGL does not do is retain information about an 'object'. All OpenGL sees is a ball of triangles and a bag of state with which to render them. It does not remember that you drew a line in one location and a sphere in another.
Because of that, the general way to use OpenGL is to draw everything you need to draw, then show this image with a platform-dependent buffer swapping command. If you need to update the image, you draw everything again, even if you only need to update part of the image. If you want to animate objects moving on the screen, you need a loop that constantly clears and redraws the screen.
There are techniques for only updating a portion of the screen. And you can use OpenGL with these techniques. But OpenGL itself doesn't do it internally; you must remember where you drew everything. You must figure out what needs updating and clear only that part of the screen. And so forth.
There are many tutorials and other materials available for learning how to use OpenGL, both on this wiki and online.
OpenGL Viewers
These are programs that you install and run, and they give you information specific to the OpenGL API your system implements, like the version offered by your system, the vendor, the renderer, the extension list, supported viewport size, line size, point size, plus many other details. Some might include a benchmark. Some are standalone benchmarks.
