Changelog

[1.3.2] - 2024-01-11

Fixed

• Fixed math.hash crash when using IL2CPP builds on Arm 32 bit devices.
• Fixed obsolete method usage warnings for MatrixDrawer.CanCacheInspectorGUI and PrimitiveVectorDrawer.CanCacheInspectorGUI in UNITY_2023_2_OR_NEWER.
• Updated minimum editor version to 2021.3

[1.3.1] - 2023-07-12

Added

• Added math.square to compute the square (x * x).
• Added math.orthonormal_basis to compute an orthonormal basis from a single unit length vector.
• Added math.sign for int, int2, int3 and int4.
• Added math.chgsign for float, float2, float3, and float4.
• Added math.Euler to convert a quaternion to Euler angles.
• Added math.angle to compute the angle between two unit quaternions.
• Added math.rotation to extract a quaternion rotation from a float3x3 (that may have scale).
• Added math.mulScale to scale columns of a float3x3 with scaling coefficients in a float3.
• Added math.scaleMul to scale rows of a float3x3 with scaling coefficients in a float3.
• Added AffineTransform type.
• Added PI2, PIHALF, TAU, TODEGREES and TORADIANS constants.

Changed

• asfloat(uint), asuint(float), asint(float) and other related methods are now faster in mono without Burst. Other methods which use these will see a performance improvement.
• Modified quaternion.nlerp to be branchless.
• More descriptive parameter names for many methods in math class.
• Made Il2CppEagerStaticClassConstructionAttribute internal to avoid conflicts with other definitions outside of the package.

[1.2.6] - 2022-02-11

Changed

• Made Il2CppEagerStaticClassConstructionAttribute internal to avoid conflicts with other definitions outside of the package.

[1.2.5] - 2021-11-01

Fixed

• Fixed property drawing when manually drawing a property that was hidden with [HideInInspector].

[1.2.4] - 2021-09-22

Added

• Added [Il2CppEagerStaticClassConstruction] to Unity.Mathematics types to run static constructors at startup. This improves IL2CPP performance slightly for types that have static constructors.

Changed

• License file updated to satisfy Unity's package validation tests.
• Changed noise documentation in comments to xmldoc comments.

Fixed

• Fixed Equals(object) override which did not check type before casting. This could cause exceptions to be thrown when the object did not match the expected type.
• Fixed incorrect math.tzcnt documentation which mentioned leading zero counts instead of trailing zero counts.
• Fixed float2x2.Rotate documentation to mention radians instead of degrees.
• Fixed documentation for methods and properties that were previously undocumented.

[1.2.1] - 2020-08-06

Fixed

• Fixed warnings for meta files existing even though the files they represent did not exist.

Internal (Not ready for production)

[1.2.0] - 2020-08-03

Added

• Added [MethodImpl(MethodImplOptions.AggressiveInlining)] to many static functions to improve IL2CPP performance.
• Added compress() that accepts a float4 and uint4.
• Added math.project() and math.projectsafe() for vector projection.
• Added math.EPSILON, math.INFINITY, math.NAN and their double counterparts.
• Added [Serializable] to RigidTransform.
• Added math.ceillog2().
• Added math.floorlog2().
• Added math.down(), math.forward(), etc for Cartesian coordinate axes that match UnityEngine Vector3 equivalents.
• Added math.ispow2().
• Added half.MinValueAsHalf and half.MaxValueAsHalf to avoid having to explicitly convert from float.
• Added a float3x3 constructor which takes a float4x4 as input.
• Added [Serializable] to half types.
• Added some performance tests which can be run from the Unity test project.
• Added Random.CreateFromIndex() to assist in creating Random instances from loop indices.

Fixed

• Fixed documentation bug where quaternion.RotateX/Y/Z referred to a float4x4 instead of quaternion.
• Fixed code generation bugs which could cause Windows and Mac to generate different test code.
• Fixed some test asserts which used NaNs and signed zeros which failed in IL2CPP builds.
• Updated documentation for math.countbits() to include equivalent names on Intel and ARM architectures to aid in discoverability.

Internal (Not ready for production)

• Added Unity.Mathematics.Geometry.Plane to represent planes in 3D space.
• Added more MinMaxAABB functionality from Unity.Physics.Aabb.
• Added Unity.Mathematics.Geometry.Math to hold static functions like AABB transformations.
• Added MinMaxAABB.

[1.1.0] - 2019-07-08

• Release stable version

[1.1.0-preview.1] - 2019-06-27

• Add new math.bitmask to return a bit mask from a bool4

[1.0.1] - 2019-04-15

• Release stable version
• Modify all math constants (e.g math.PI) to provide float constant by default instead of double. Use for example math.PI_DBL to get the previous double constant.

[1.0.0-preview.1] - 2019-02-28

• Fixed bug where modifications on prefabs could not be reverted for vector properties when using context menu in Inspector.
• Fixed structure of the package for internal validation
