Changelog

[main]

  • Adding TransposableMatrixType protocol to describe matrices that can be transposed into another known matrix type.

  • Added DivisibleRectangleType.subdivided().

  • Fixing NSphere.project(_:Vector) being offset from correct point by -self.center.

  • TakeVector3 has been removed in favor of VectorTakeable protocol.

  • Forcing Vector3- specializing protocols to require the same specialization on its SubVector4, e.g. Vector3FloatingPoint now requires SubVector4: Vector4FloatingPoint.

  • Added Vector3Multiplicative.tripleProduct method.

  • Forcing Vector2- specializing protocols to require the same specialization on its SubVector3, e.g. Vector2FloatingPoint now requires SubVector3: Vector3FloatingPoint.

  • Added Vector2Multiplicative.tripleProduct method.

  • Added NSquare.vertices when NSquare.Vector conforms to VectorAdditive.

  • Added LineCategory bit-flag for LineType conformers that specifies the category of the line type (line, ray, or line segment).

  • Added PlaneIntersectablePlane2Type to generalize line intersection of 1D planes (lines) in 2D spaces.

  • Added PlaneIntersectablePlane3Type to generalize line intersection of 2D planes in 3D spaces.

v0.0.2

  • Added Hyperplane protocol to represent hyperplanes, along with proper type aliases for 2-, 3-, and 4-dimensional hyperplanes.

  • Added VectorTakeable protocol, and making all vector protocols conform to it. With it, it’s possible to index into a vector type to produce different vector types based on combinations of dimensions of a vector:

let vector = Vector3D(x: 3.5, y: 2.1, z: 1.0)

print(vector[.x, .z]) // Prints "(x: 3.5, y: 1.0)"
print(vector[.x, .z, .y]) // Prints "(x: 3.5, y: 1.0, z: 2.1)"
print(vector[.z, .y, .x]) // Prints "(x: 1.0, y: 2.1, x: 3.5)"
print(vector[.z, .y, .x, .z]) // Prints "(x: 1.0, y: 2.1, x: 3.5, w: 1.0)"

  • Added Vector<2/3/4>TakeDimensions to accompany the VectorTakeable protocol and serve as a default conformance to Vector<2/3/4>Type protocols.

  • Added AdditiveRectangle.vertices getter, which is automatically synthesized for any conforming type.
