The State of Vulkan on Apple 03June 2021
The State of Vulkan on Apple Devices Why you should be developing for the Apple ecosystem with Vulkan, and how to do it. Richard S. Wright Jr., LunarG June 3, 2021 If you are reading this, you likely already know what Vulkan is -- a low-overhead, high-performance, cross-platform, graphics and compute API designed to take maximum advantage of today's highly parallel and scalable graphics and compute hardware. To be sure, there are other APIs with this goal such as Microsoft’s DirectX and Apple’s Metal API. For a long time OpenGL matured to meet the needs of rapidly evolving hardware and met well the challenges of cross-platform development of high-performance graphics applications. OpenGL will remain viable for a very long time for many applications (and can actually be layered on top of Vulkan), but to take maximum advantage of modern hardware, a new and somewhat reinvented approach is called for. Everyone does not need the level of control that Vulkan provides, but if you do, you can think of Vulkan as a lower-level successor to OpenGL in that it attempts to enable highly portable, yet high-performance, application development across desktop and mobile device platforms. Writing platform specific code does have its advantages, and vendors such as Microsoft and Apple certainly adore having best of breed titles available exclusively for their customers as it adds value to their ecosystem. For developers though, it is often in our best interests to make our products available as widely as possible. Aside from gaming consoles with their mostly closed development environments, Windows, Linux, Apple, and Android combined represent most of the market for developers of end user software and games today.
