Opengl Development For Mac
Posted By admin On 04.03.20. Apple announced during its annual Worldwide Developers Conference that OpenGL, a longtime tool for game developers, will 'no longer be used in active development' on MacOS and instead, encouraged them to adopt Metal, its newer, proprietary tool.
Some video game developers hinted at abandoning support for Macs, while others believed it was a prudent decision. Although Apple offered some relief with a 'grace period' and assured that the old tools will remain usable 'for a reasonable time,' the general consensus amongst developers is OpenGL is in its final death throes. While Apple's annual brought cheers on Monday, many game developers grew uneasy after the company that OpenGL, a longtime tool and open standard, will 'no longer be used in active development' starting with MacOS Mojave, the new version launching later this year.
Some developers were taken aback by the announcement. OpenGL is a widely used graphics application programming interface (API) that allows software to interact with different hardware seamlessly.
It helps to think of OpenGL as the middleman between a game and a PC's graphics card. If you ever installed a video game on a Mac, chances are good that developers used OpenGL. Among its other virtues, using OpenGL can cut time in bringing their games over from Windows or even iPhone, and vice versa.
And without an API like OpenGL, developers would have to start from scratch on every new platform. OpenGL, first developed in the '90s, has a robust following, and is considered the common language for graphics programmers due to it being an open standard that works on most platforms. Now, Apple is saying that they won't be supporting future versions of MacOS to work with OpenGL, and could indeed remove OpenGL support at any time. Apple unveils MacOS Mojave at its WWDC 2018 conference.
Screenshot 'When a deprecation occurs, it’s not an immediate end of life for the specified API,' Apple said in its latest release notes. 'Instead, it is the beginning of a grace period for transitioning from that API and to newer and more modern replacements.' Indeed, Apple will push Metal — its own graphics API, which is only found on the iPhone, iPad and, with the MacOS update, all Mac computers. First released in 2014, Apple's Metal is certainly 'more modern' than OpenGL, which has its roots in the early days of 3D gaming. The decision has split the developer community. Some game developers hinted at abandoning support for Macs entirely over the change, while others believed it was a prudent decision. Still, the consensus opinion seems to be that while the move was surprising, OpenGL was likely on its last legs regardless of what Apple did or didn't do.
'It's a pretty smart move,' startup game developer Sam Loeschen said to Business Insider. 'It kind of sucks because most people using OpenGL are a lot of indie teams, but unfortunately, they're in the fair minority.'
And major games, such as Epic Games' 'Fortnite,' already to be compatible with Metal in order to run, indicating that major developers have already began adopting the API. It could still pose an increased challenge for smaller teams and indie games, who may have to update all of their games to use Metal instead of OpenGL. Apple, for its part, seems to understand the hassle this change could cause. To that end, it's hyping up the benefits of Metal to developers over its alternatives. 'Fortnite: Battle Royale' on a PlayStation 4. The Mac version uses Metal to power its graphics. Dave Smith/Business Insider 'Games and graphics-intensive apps that use OpenGL should now adopt Metal,' Apple said in its release notes.
'Metal avoids the overhead inherent in legacy technologies and exposes the latest graphics processing functionality.' Developers familiar with Metal agreed with Apple's assessment: 'I can write a Metal application that will run on an iPhone and it will look the same on my Mac computer without having to do much internal plumbing,' Loeschen said. 'I can do multiple commands all in the same area. It's just all there.' And Apple offered some relief with a 'grace period' and assured that OpenGL will remain usable 'for a reasonable time.' Dan Omachi, a Metal developer liaison, noted to that Apple provides several tools for developers not proficient in Metal to ease the transition. Here's a glimpse at the conversation, via developers on Twitter.
Welp, it's not like anyone used OpenGL for their OSX ports, right?.nervous laugh. — Rami Ismail (@tharami) Ultimately, Apple's move could end up having a profound impact for Mac game developers. While Windows PCs have been synonymous with video games for decades now, Apple's Macs have long been a punchline among gamers — while there are a handful of big-ticket games available for MacOS, like 'Diablo III' and 'ARK: Survival Evolved,' Apple has rarely given Macs the hardware to compete graphically with a similarly-priced Windows PC, and most game developers don't even bother.
Indeed, many, if not most, of the best-selling Mac games are independent titles, made by relatively small teams: 'Stardew Valley,' 'Rocket League,' and 'Rust' are all popular on Macs. This problem becomes even more apparent when you take a look at a 'top 10' supported for Macs — nearly every compilation contains indie titles. This means that the focus away from OpenGL and towards Metal could have an outsized impact the smallest developers, who also contribute many of its most popular video games. They may not have the resources or time to update their games to keep up, and thus, gaming on the Mac could be jeopardized even further.

Important OpenGL was deprecated in macOS 10.14. To create high-performance code on GPUs, use the Metal framework instead. OpenGL is an open, cross-platform graphics standard with broad industry support. OpenGL greatly eases the task of writing real-time 2D or 3D graphics applications by providing a mature, well-documented graphics processing pipeline that supports the abstraction of current and future hardware accelerators. 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. Relevant Chapters:, and 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. Relevant Chapters:, and OpenGL Helps Applications Harness the Power of Graphics Processors Graphics processors are massively parallelized devices optimized for graphics operations. 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.
Relevant Chapters:, and 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.
Relevant Chapters: 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. Relevant Chapters:, 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. Critical Mac terminology is defined in that chapter as well as in the. If you already have an OpenGL application running on the Mac, but have not yet updated it for OS X v10.7, read 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.
Once you have OpenGL content in your application, read 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 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 to get an overview of OpenGL on the Mac platform, and then read the following OpenGL programming guide and reference documents:., by Dave Shreiner and the Khronos OpenGL Working Group; otherwise known as 'The Red book.”. OpenGL Shading Language, by Randi J.
Rost, is an excellent guide for those who want to write programs that compute surface properties (also known as shaders). Before reading this document, you should be familiar with Cocoa windows and views as introduced in. See Also Keep these reference documents handy as you develop your OpenGL program for OS X:., and provide a complete description of the classes and methods needed to integrate OpenGL content into a Cocoa application. CGL Reference describes low-level functions that can be used to create full-screen OpenGL applications.

OpenGL Extensions Guide provides information about OpenGL extensions supported in OS X. The OpenGL Foundation website, provides information on OpenGL commands, the Khronos OpenGL Working Group, logo requirements, OpenGL news, and many other topics. It's a site that you'll want to visit regularly. Among the many resources it provides, the following are important reference documents for OpenGL developers:. OpenGL Specification provides detailed information on how an OpenGL implementation is expected to handle each OpenGL command. OpenGL Reference describes the main OpenGL library. OpenGL GLU Reference describes the OpenGL Utility Library, which contains convenience functions implemented on top of the OpenGL API.
OpenGL GLUT Reference describes the OpenGL Utility Toolkit, a cross-platform windowing API. provides code examples for fundamental tasks, such as modeling and texture mapping, as well as for advanced techniques, such as high dynamic range rendering (HDRR).
