Added

• Added missing Serialize, Deserialize and PartialEq implementations.

• Added Sum<Self> and Product<Self> implementations for all vector, matrix and quaternion types.

• Added 4x4 matrix methods look_to_lh and look_to_rh. These were previously private.

• Added is_negative_bitmask to vector types which returns a u32 of bits for each negative vector lane.

• Added splat method and TRUE and FALSE constants to all BVec types.

• Added from_mat3a methods to Affine2, Mat2, Mat4 and Quat types.

Changed

• Disable serde default features.

0.21.3 - 2022-08-02

Fixed

• Fixed glam_assert being too restrictive in matrix transform point and transform vector methods.

Added

• Added experimental core-simd feature which enables SIMD support via the unstable core::simd module.

Changed

• Derive from PartialEq and Eq instead of providing a trait implementation for all non SIMD types.

0.21.2 - 2022-06-25

Fixed

• Restore missing $crate:: prefix in deprecated const_* macros.

• Fixed some performance regressions in affine and matrix determinant and inverses due to lack of inlining.

0.21.1 - 2022-06-22

Fixed

• Fix compilation when FMA support is enabled.

0.21.0 - 2022-06-22

Breaking changes

• Minimum Supported Version of Rust bumped to 1.58.1 to allow const pointer dereferences in constant evaluation.

• The abs_diff_eq method on Mat2 and DMat2 now takes other by value instead of reference. This is consistent with the other matrix types.

• The AsRef trait implementations were removed from BVec2, BVec3, BVec3A, BVec4 and BVec4A.

Added

• NEG_ONE constant was added to all signed vector types.

• NEG_X, NEG_Y, NEG_Z and NEG_W negative axis vectors were added to signed vector types.

• The from_array const function was added to all vector types.

Changed

• Source code is now largely generated. This removes most usage of macros internally to improve readability. There should be no change in API or behavior other than what is documented here.

Added

• Added from_cols() methods to affine types.
• Added methods for reading and writing affine types from and to arrays and slices, including from_cols_array(), to_cols_array(), from_cols_array_2d(), to_cols_array_2d(), from_cols_slice() and write_cols_to_slice().

Changed

• Disable const_assert_eq! size and alignment checks for SPIR-V targets.

Breaking changes

• Removed PartialOrd and Ord trait implementations for all glam types.
• Removed deprecated zero(), one(), unit_x(), unit_y(), unit_z(), unit_w(), identity() and Mat2::scale() methods.
• Remove problematic Quat From trait conversions which would allow creating a non-uniform quaternion without necessarily realising, including from Vec4, (x, y, z, w) and [f32; 4].

Added

• Added EulerRot enum for specifying Euler rotation order and Quat::from_euler(), Mat3::from_euler() and Mat4::from_euler() which support specifying a rotation order and angles of rotation.
• Added Quat::to_euler() method for extracting Euler angles.
• Added Quat::from_vec4() which is an explicit method for creating a quaternion from a 4D vector. The method does not normalize the resulting quaternion.
• Added Mat3A type which uses Vec3A columns. It is 16 byte aligned and contains internal padding but it generally faster than Mat3 for most operations if SIMD is available.
• Added 3D affine transform types Affine3A and DAffine3. These are more efficient than using Mat4 and DMat4 respectively when working with 3D affine transforms.

0.13.0 - 2021-03-04

Breaking Changes

• The behavior of the 4x4 matrix method transform_point3() was changed to not perform the perspective divide. This is an optimization for use with affine transforms where perspective correction is not required. The project_point3() method was added for transforming points by perspective projections.
• The 3x3 matrix from_scale() method was changed to create a affine transform containing a 2-dimensional non-uniform scale to be consistent with the 4x4 matrix version. The from_diagonal() method can be used to create a 3x3 scale matrix.

• Added quaternion inverse() which assumes the quaternion is already normalized and returns the conjugate.
• Added from_translation() and from_angle() methods to 3x3 matrix types.
• Added project_point3() method to 4x4 matrix types. This method is for transforming 3D vectors by perspective projection transforms.
• Added Eq and Hash impls for integer vector types.

Changed

0.10.0 - 2020-10-31

Breaking Changes

• Changed the return type of Vec4::truncate from Vec3A to Vec3.

Added

• Added From implementations to truncate to narrower vector types, e.g. Vec4 to Vec3A, Vec3 and Vec2 and from Vec3A and Vec3 to Vec2.
• Added swizzles for Vec4, Vec3A, Vec3 and Vec2. These can be used to reorder elements in the same type and also to create larger or smaller vectors from the given vectors elements.
• Added Quat operators Add<Quat>, Sub<Quat>, Mul<f32> and Div<f32. These are used by other crates for interpolation quaternions along splines. Note that these operations will not return unit length quaternions, thus the results must be normalized before performing other Quat operations.
• Added Mat4::transform_point3a and Mat4::transform_vector3a.
• Added AsRef<[f32; 9]> and AsMut<[f32; 9]> trait implementations to Mat3.
• Added optional bytemuck support primarily for casting types to &[u8].

Removed

• Removed deprecated function Mat4::perspective_glu_rh.

0.9.4 - 2020-08-31

• The From trait implementation converting between 1D and 2D f32 arrays and matrix types have been removed. It was ambiguous how array data would map to matrix columns so these have been replaced with explicit methods from_cols_array and from_cols_array_2d.
• Matrix new methods have been renamed to from_cols to be consistent with the other methods that create matrices from data.
• Renamed Mat4::perspective_glu to Mat4::perspective_glu_rh.

• Added is_normalized method to Vec2, Vec3 and Vec4.

Changed

• Replaced usage of std::mem::uninitialized with std::mem::MaybeUninit. This change requires stable Rust 1.36.

0.6.0 - 2019-06-13

Changed

• Switched from row vectors to column vectors
• Vectors are now on the right of multiplications with matrices and quaternions.
