Thanks for having a look at MetalGL!
Can you clarify what you are asking?
Are you asking whether MetalGL will bring additional graphics technologies (such as DX) from those platforms to iOS & OSX? If so, we’re certainly looking into that!
Or are you asking whether we will port MetalGL to those other platforms, using native enhancement technologies? For now, MetalGL is focused on bringing compatibility and performance to the iOS and OSX platforms, by using Metal as a performance enhancer. Later on, we may use similar performance technologies and expertise on those other platforms, but that will be further down the road.
Or are you asking something else that I haven’t picked up on?
