What's New

Minor API improvements


A fully generic Swift vector & matrix library

Carthage compatible


Version 4.2.0

  • Default conformance to Hashable
  • Conversion between different types of IntVectors
  • Common aliases for x, y, z, w. For example r, g, b, a.

Version 4.1.0

  • Added IntVector 2, 3, and 4
  • Added bitwise shifts to IntVector
  • Added overflow and underflow operators to IntVector
  • Added conversion initializers between Int and Float vectors

Version 4.0.0

  • Simplified API by removing Integer support, most useful functions require trigonometry or not truncating division.
  • Made functions follow Swift conventions better by making them static methods on the type instead of global functions.
  • Removed the Angle type as it made things more complicated than the benefits it may have provided.
  • Removed the Rectangle type as it was not used in any algorithms and was mostly desinged for use with Integers which were removed.

Version 3.1.2

  • zubco Make sure Float80 is only compiled for Intel

Version 3.1.1

  • zubco added Bounds2 & Bounds3 contains(point:) and intersection(other:) methods.

Version 3.1.0

  • Fix Vector3 xAxis
  • Turn Vector3 axis methods into static properties
  • Simplify Transform3 matrix & inverseMatrix methods to not use conditionals

Version 3.0.0

  • Updated for Swift 4

Version 2.0.0

  • Updated for Swift 3
  • Swift Package Manager support
  • Geometry and intersection tests

Version 1.0.2

  • Forgot to make typealias public
  • Fixed approx to always use <=

Version 1.0.1

  • Started adding tests
  • Added some aliases for common sizes and element types
  • Tightened up the Arithmetic protocols
  • Implemented approximately equal function and operator
  • Made Vector & Matrix classes conform to Printable
  • Verified that a switch statement is the best way to implement subscripting
  • Now have access to the rows of a Matrix
