(If my below examples (that involve frameworks like Accelerate and SceneKit) are off-topic, perhaps the main question can be answered anyway.)
Now that SE-0229 SIMD has been accepted with modifications, I'd like to know if there are any plans for what the migration process will be like (from existing "
import simd"-types, eg
float3 to the new
SIMD3<Float>). I did a quick search of the forums (review thread here) but couldn't find anything mentioned about it.
In macOS 10.13, iOS 11, tvOS 11, and watchOS 4 (or later), use data types provided by the system SIMD library (such as float3 and float4x4) and the corresponding SceneKit methods (such as simdPosition and simdTransform) instead. These types provide faster performance, offer more concise C, C++, and Swift syntax (such as + and * operators instead of functions), and interoperate better with other technologies (such as Model I/O, GameplayKit, and the Metal Shading Language).
So when the new SIMD vector types have landed, will eg
float3 continue to live on the side of
SIMD4<Float>, and if so, will they be bridged in some way?
Will eg SceneKit's SCNNode's current
be changed to
and if so, what will the types of its
simdPivot properties be?
