metal-cpp-extensions

C++ bindings into Apple's platform SDK to help with using Metal directly from C++. The majority of the code is from Apple, taken from their Learn Metal with C++ example but with some things added by me. This will probably never be an exhaustive set of bindings, I just add what I need when I need them.

Additions to Apple's code

• AppKit
  • NS::GridView
    • only creating from an NS::Array of NS::Arrays of NS::Views.
  • NS::StackView
    • only creating from an NS::Array NS::Views.
    • allows setting orientation.
    • allows setting the distribution.
• MetalKit
  • MTK::TextureLoader
    • only has the MTL::Texture* newTexture( const NS::URL* URL, const NS::Dictionary* options, NS::Error** error ); method, and I haven't tested setting anything other than nullptr for the options.
• Metal Performance Shaders
  • MPS::Image
    • only has creation from MTL::Texture and MPS::ImageDescriptor; and conversion back to MTL::Texture.
  • MPS::ImageGaussianBlur
  • MPS::ImageGaussianPyramid
    • Only the in place encode method works. I think this is an MPS internal thing, see Apple's [documentation for MPSImageGaussianPyramid] (https://developer.apple.com/documentation/metalperformanceshaders/mpsimagegaussianpyramid?language=objc).
  • MPS::ImageSubtract
