ARHeadsetUtil

A conglomeration of utility functions from ARHeadsetKit, brought to every Apple platform. These include extensions to Metal, simd, and other frameworks that improve usability and make optimization easier. In addition, ARHeadsetUtil includes math utility functions that replace the AAPLMathUtilities.m library from Metal sample code.

MTLLayeredBuffer is not included in this package. For more information, check out its repository and article.

Why was ARHeadsetUtil created?

ARHeadsetKit is centered around iOS, but its utility functions aren't. In addition, ARHeadsetKit requires iOS 14, while the utility functions can work on earlier versions of iOS and on all Apple platforms. So, they were copied from ARHeadsetKit into this package.

What projects use ARHeadsetKit/ARHeadsetUtil?

The following open-source projects:

• AR MultiPendulum - the first affordable AR headset experience
• Differentiation iOS Demo - sample of Swift's automatic differentiation working on iOS
• MetalFFT - the Fast Fourier Transforms missing from Metal Performance Shaders

Are ARHeadsetKit and ARHeadsetUtil the same?

No. ARHeadsetUtil is a stripped down version of ARHeadsetKit, omitting all the code related to AR. ARHeadsetKit does not have a Swift package dependency to ARHeadsetUtil, although the utilities from ARHeadsetUtil are the exact same as those in ARHeadsetKit.

Why doesn't ARHeadsetKit depend on ARHeadsetUtil?

DocC documentation doesn't allow linking between separate frameworks within the Xcode documentation viewer. Although one could link to online documentation, DocC can't be hosted online yet. If this problem didn't exist, ARHeadsetKit would have a Swift package dependency to ARHeadsetUtil.
