The Brenwill Workshop Ltd. announces the availability of MetalGL, which seamlessly brings the performance of Metal to OpenGL games and applications on iOS devices.

MetalGL is an implementation of the  OpenGL ES 2.0 API that runs on Apple’s  Metal graphics framework on compatible iOS devices. With MetalGL,  OpenGL developers get many of the performance benefits of  Metal, without having to abandon the proven and familiar  OpenGL ES 2.0 API, or rewrite rendering logic and shaders for a different platform.

MetalGL unleashes the power of  Metal’s low-latency rendering to let OpenGL games and applications perform up to 3x the number of draw calls, all without changing the way the game or app use  OpenGL.

It’s all automatic. Developers can continue to use a single  OpenGL API to build games and applications that run unchanged across multiple devices, platforms, and operating systems, including those that support Metal.  MetalGL automatically detects whether the iOS device supports  Metal, and will use it where available. This automatic portability even extends to shaders, as  MetalGL will convert GLSL shaders to their  Metal Shading Language  equivalents, either automatically and transparently at run time, or at development time using  MetalGL’s shader conversion tools.

“With MetalGL, developers have the opportunity to triple the performance of their  OpenGL ES 2.0 games and apps on iOS devices without having to rewrite a single line of their game logic, OpenGL framework calls, or shaders”, said Bill Hollings, President of The Brenwill Workshop Ltd., the creators of MetalGL.
