Angle running on top of MoltenVK , implemented for iOS and Mac

[Eli X]

Hi all , just F.Y.I

I have implemented  "Angle running on top of MoltenVK" solution as part of an game engine.

You can read about it and try it out  :

https://discourse.urho3d.io/t/metal-moltenvk-support-for-ios-an-mac-devices/4845

The branch with the code :

https://github.com/elix22/Urho3D/tree/angle-vulkan 

git clone -b angle-vulkan https://github.com/elix22/Urho3D.git

I have created 4 scripts that will create for you the Xcode projects  with all the samples:

cmake_ios-metal.sh - will create an iOS Xcode project using the metal backend (my work)
cmake_ios-gles.sh - will create an iOS Xcode project using the default OpenGL-ES backend
cmake_xcode-metal.sh - will create an Mac Xcode project using the metal backend (my work)
cmake_xcode-gl.sh - will create an Mac Xcode project using the default OpenGL-ES backend

For the Metal projects , In order to get the best performance you will have to modify the scheme to release build configuration and also disable metal API validation .

Everyone is free to use it for any purpose

Enjoy!

Very cool Eli. Thanks for sharing. How is the performance?

Performance is very good , 

On 99 % of the samples I am getting stable 60 FPS on my iPad , scheme configured to build release and Metal Api validation disabled.

Only 1 sample shows poor performance , 20_HugeObjectCount  , simulating 62500 draw-calls every frame.

Angle/Vulkan/MoltenGL : 7-9 FPS

GLES2 : 19 - 33 FPS

I added also Angle-Vulkan support for Windows , to be used as reference/test-bed   (my main objective is supporting MoltenVK)

You can use it If you wish to see how Angle-Vulkan performs while rendering complex scenes (and not only rendering of a simple cube) ,

You can read my Wiki on how to use it (both on Window-Vulkan and Mac/iOS-MoltenVK)

Hey Eli,

Following up on this message from February 2019.

You've done some really great work here. Would you be willing to contribute this work to ANGLE? Either via contributing it yourself or an ANGLE developer integrating it upstream?

[Eli X]

Hey Jamie ,

Feel free to integrate my stuff into ANGLE upstream , you have my consent.

Please look at this branch , it's the most recent one .

Hey, just wanted to check if this has been committed upstream yet (and if so, how to "enable" it) as I was interested in its GLES2 performance compared to the standard Metal backing renderer.

This was more a Game Engine centric implementation 

However you can use the excellent "Angle (GLES2/GLES3) On top of Metal" implementation created by @kakashidinho

You can find it here 

https://github.com/kakashidinho/metalangle

I guess some of it already made into upstream  (not all of it)

I personally find it to be more performant  than Angle on MoltenVK 

[Hamish Arblaster]

Okay, thanks.

I'll be sure to give it a go!

[Jamie Madill]

Most of the work in that repo has also been integrated upstream, thanks to Quyen.
