This repository is now archived. The algorithms in this Swift package are not performant and it is recommended that you use SIMDExtensions if you are looking for an explicitly typed way of doing vector arithmetic. SIMD is made easy with Apple's framework, and SIMDExtensions is an API that cuts down on the effort of reading through code documentation to figure out what c-style SIMD function will work with what SIMD types. It also includes utilities similar to the ones present in this project. This repository will remain here for educational purposes because it showcases the power of the protocol-oriented nature of Swift.
This swift package defines protocols that provide useful default implementations for various Vector data types. Thanks to Swift's protocol composition, you can apply these protocols and gain incredibly useful vector functions. This package is a dependency of the VectorExtensions package, which is a core component powering FieldFab for iOS.
import VectorProtocol
struct <# Vector Type #>: Vector {
public typealias BFP = <# BinaryFloatingPoint #>
public typealias Axis = <# Axis Enumeration #> // Enum must conform to Axis protocol
public subscript(axis: Axis) -> BFP {
get {
switch axis {
<# Get Accessor Cases #>
}
}
set(v) {
switch axis {
<# Set Accessor Cases #>
}
}
}
}
// Or as an extension of an existing vector type
extension SCNVector3: Vector {
// Same code as above
}
