# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog], and this project adheres to
[Semantic Versioning].
## [Unreleased]
## [0.8.7] - 2020-04-28
### Added
* Added `Quat::slerp` - note that this uses a `sin` approximation.
* Added `angle_between` method for `Vec2` and `Vec3`.
* Implemented `Debug`, `Display`, `PartialEq`, `Eq`, `PartialOrd`, `Ord`,
`Hash`, and `AsRef` traits for `Vec2Mask`, `Vec3Mask` and `Vec4Mask`.
* Added conversion functions from `Vec2Mask`, `Vec3Mask` and `Vec4Mask` to an
array of `[u32]`.
* Added `build.rs` to simplify conditional feature compilation.
### Changed
* Removed `cfg-if` dependency.
* Increased test coverage.
## [0.8.6] - 2020-02-18
### Added
* Added the `packed-vec3` feature flag to disable using SIMD types for `Vec3`
and `Mat3` types. This avoids wasting some space due to 16 byte alignment at
the cost of some performance.
* Added `x_mut`, `y_mut`, `z_mut`, `w_mut` where appropriate to `Vec2`, `Vec3`
and `Vec4`.
* Added implementation of `core::ops::Index` and `core::ops::IndexMut` for
`Vec2`, `Vec3` and `Vec4`.
### Changed
* Merged SSE2 and scalar `Vec3` and `Vec4` implementations into single files
using the `cfg-if` crate.
## [0.8.5] - 2020-01-02
### Added
* Added projection functions `Mat4::perspective_lh`,
`Mat4::perspective_infinite_lh`, `Mat4::perspective_infinite_reverse_lh`,
`Mat4::orthgraphic_lh` and `Mat4::orthographic_rh`.
* Added `round`, `ceil` and `floor` methods to `Vec2`, `Vec3` and `Vec4`.
## [0.8.4] - 2019-12-17
### Added
* Added `Mat4::to_scale_rotation_translation` for extracting scale, rotation and
translation from a 4x4 homogeneous transformation matrix.
* Added `cargo-deny` GitHub Action.
### Changed
* Renamed `Quat::new` to `Quat::from_xyzw`.
## [0.8.3] - 2019-11-27
### Added
* Added `Mat4::orthographic_rh_gl`.
### Changed
* Renamed `Mat4::perspective_glu_rh` to `Mat4::perspective_rh_gl`.
* SSE2 optimizations for `Mat2::determinant`, `Mat2::inverse`,
`Mat2::transpose`, `Mat3::transpose`, `Quat::conjugate`, `Quat::lerp`,
`Quat::mul_vec3`, `Quat::mul_quat` and `Quat::from_rotation_ypr`.
* Disabled optimizations to `Mat4::transform_point3` and
`Mat4::transform_vector3` as they are probably incorrect and need
investigating.
* Added missing `#[repr(C)]` to `Mat2`, `Mat3` and `Mat4`.
* Benchmarks now store output of functions to better estimate the cost of a
function call.
### Removed
* Removed deprecated functions `Mat2::new`, `Mat3::new` and `Mat4::new`.
## [0.8.2] - 2019-11-06
### Changed
* `glam_assert!` is no longer enabled by default in debug builds, it can be
enabled in any configuration using the `glam-assert` feature or in debug
builds only using the `debug-glam-assert` feature.
### Removed
* `glam_assert!`'s checking `lerp` is bounded between 0.0 and 1.0 and that
matrix scales are non-zero have been removed.
## [0.8.1] - 2019-11-03
### Added
* Added `Display` trait implementations for `Mat2`, `Mat3` and `Mat4`.
### Changed
* Disabled `glam`'s SSE2 `sin_cos` implementation - it became less precise for
large angle values.
* Reduced the default epsilon used by the `is_normalized!` macro from
`std::f32::EPSILON` to `1e-6`.
## [0.8.0] - 2019-10-14
### Removed
* Removed the `approx` crate dependency. Each `glam` type has an `abs_diff_eq`
method added which is used by unit tests for approximate floating point
comparisons.
* Removed the `Angle` type. All angles are now `f32` and are expected to
be in radians.
* Removed the deprecated `Vec2b`, `Vec3b` and `Vec4b` types and the `mask`
methods on `Vec2Mask`, `Vec3Mask` and `Vec4Mask`.
### Changed
* The `rand` crate dependency has been removed from default features. This was
required for benchmarking but a simple random number generator has been added
to the benches `support` module instead.
* 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`.
## [0.7.2] - 2019-09-22
### Fixed
* Fixed incorrect projection matrix methods `Mat4::look_at_lh`
and `Mat4::look_at_rh`.
### Added
* Added support for building infinite projection matrices, including both
standard and reverse depth `Mat4::perspective_infinite_rh` and
`Mat4::perspective_infinite_rh`.
* Added `Vec2Mask::new`, `Vec3Mask::new` and `Vec4Mask::new` methods.
* Implemented `std::ops` `BitAnd`, `BitAndAssign`, `BitOr`, `BitOrAssign`
and `Not` traits for `Vec2Mask`, `Vec3Mask` and `Vec4Mask`.
* Added method documentation for `Vec4` and `Vec4Mask` types.
* Added missing `serde` implementations for `Mat2`, `Mat3` and `Mat4`.
* Updated `rand` and `criterion` versions.
## [0.7.1] - 2019-07-08
### Fixed
* The SSE2 implementation of `Vec4` `dot` was missing a shuffle, meaning the
`dot`, `length`, `length_squared`, `length_reciprocal` and `normalize`
methods were sometimes incorrect.
### Added
* Added the `glam_assert` macro which behaves like Rust's `debug_assert` but
can be enabled separately to `debug_assert`. This is used to perform
asserts on correctness.
* 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.
* Renamed `Vec2b` to `Vec2Mask`, `Vec3b` to `Vec3Mask` and `Vec4b` to
`Vec4Mask`. Old names are aliased to the new name and deprecated.
* Deprecate `VecNMask` `mask` method, use new `bitmask` method instead
* Made fallback version of `VecNMask` types the same size and alignment as the
SIMD versions.
* Added `Default` support to `VecNMask` types, will add more common traits in
the future.
* Added `#[inline]` to `mat2`, `mat3` and `mat4` functions.
## [0.7.0] - 2019-06-28
### Added
* Added `Mat2` into `[f32; 4]`, `Mat3` into `[f32; 9]` and `Mat4` into
`[f32; 16]`.
### Changed
* Removed `impl Mul<&Vec2> for Mat2` and `impl Mul<&Vec3> for Vec3` as these
don't exist for any other types.
## [0.6.1] - 2019-06-22
### Changed
* `Mat2` now uses a `Vec4` internally which gives it some performance
improvements when SSE2 is available.
## 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.

Thanks for contributing to `glam`! These guidelines will try make the process
painless and efficient.
The short guide to contributing is [open a github issue]. Pull requests are
welcome for bug fixes, documentation improvements and optimizations. For
anything else it would be best to discuss it first.
# Questions
If you have a question about the usage of this library please
[open a github issue]. That's the easiest way to get support right now.
# Bugs
If you find a bug please [open a github issue] or submit a pull request. A unit
test for any bug that slipped through existing coverage would also be greatly
appreciated.
# New functions and methods
If `glam` is missing functionality on existing types, [open a github issue]
describing what feature you would like added and ideally what your use case is
for it just so I have a better understanding of the feature. I'd like to keep
`glam` reasonably light functionality wise initially but commonly used
functionality that is missing is very welcome. If you do submit a pull request
please ensure any new functionality also has a test.
# New types
If you would like to add a new type to `glam` please [open a github issue]. Only
`f32` has been supported for now but long term I'd like to support people with
other needs. I am interested in what types you feel you need and what you would
use them for. Examples might be `i32` or `f64` vectors or generic types. I don't
want to rush to support new types until the API has stabilised a bit more but it
would be good to collect information on functionality people would like to see
in `glam`.
# Optimizations
If you feel some functionality could be optimized please [open a github issue]
or submit a pull request. Any optimization pull request should include a
benchmark if there isn't one already so I can confirm the performance
improvement.
# Documentation
If you feel any documentation could be added or improved please
[open a github issue] or submit a pull request.

# glam
[![Build Status]][travis-ci] [![Coverage Status]][coveralls.io]
[![Latest Version]][crates.io] [![docs]][docs.rs]
A simple and fast 3D math library for games and graphics.
## Development status
`glam` is in alpha stage. Minimal base functionality has been implemented
and the look and feel of the API has solidified.
## Features
* Only single precision floating point (`f32`) arithmetic is supported
* vectors: `Vec2`, `Vec3`, `Vec4`
* square matrices: `Mat2`, `Mat3`, `Mat4`
* a quaternion type: `Quat`
### SIMD
The `Vec3`, `Vec4` and `Quat` types use SSE2 on x86/x86_64 architectures.
`Mat2`, `Mat3` and `Mat4` also use SSE2 for some functionality. Not everything
has a SIMD implementation yet.
Note that this does result in some wasted space in the case of `Vec3` and `Mat3`
as the SIMD vector type is 16 bytes large and 16 byte aligned.
It is possible to opt out of using SIMD types for Vec3 and Mat3 storage with the
`packed-vec3` feature.
`glam` outperforms similar Rust libraries such as [`cgmath`][cgmath],
[`nalgebra-glm`][nalgebra-glm] and others for common operations as tested by the
[`mathbench`][mathbench] project.
If you are more concerned with size than speed you can build glam with the
feature `scalar-math` enabled to disable SIMD usage.
Due to the use of SIMD, vector elements may only be get and set via accessor
methods, e.g. `Vec3::x()` and `Vec3::x_mut()` or `Vec3::set_x()`. If getting or
setting more than one element it is more efficient to convert from tuples or
arrays:
```
let (x, y, z) = v.into();
let [x, y, z]: [f32; 3] = v.into();
```
### Optional features
* `mint` - for interoperating with other 3D math libraries
* `rand` - implementations of `Distribution` trait for all `glam` types. This
is primarily used for unit testing
* `serde` - implementations of `Serialize` and `Deserialize` for all `glam`
types. Note that serialization should work between builds of `glam` with and
without SIMD enabled
### Feature gates
* `packed-vec3` - disable using SIMD types for `Vec3` and `Mat3` storage. This
avoids wasting space due to 16 byte alignment at the cost of some performance.
* `scalar-math` - compiles with SIMD support disabled
* `glam-assert` - adds assertions which check the validity of parameters passed to
`glam` to help catch runtime errors
## Conventions
### Column vectors
`glam` interprets vectors as column matrices (also known as "column vectors")
meaning when transforming a vector with a matrix the matrix goes on the left,
e.g. `v' = Mv`. DirectX uses row vectors, OpenGL uses column vectors. There
are pros and cons to both.
### Column-major order
Matrices are stored in column major format. Each column vector is stored in
contiguous memory.
### Co-ordinate system
`glam` is co-ordinate system agnostic and intends to support both right handed
and left handed conventions.
Rotations follow the left-hand rule.
## Design Philosophy
The design of this library is guided by a desire for simplicity and good
performance.
* No traits or generics for simplicity of implementation and usage
* Only single precision floating point (`f32`) arithmetic is supported
* All dependencies are optional (e.g. `mint`, `rand` and `serde`)
* Follows the [Rust API Guidelines] where possible
* Aiming for 100% test [coverage][coveralls.io]
* Common functionality is benchmarked using [Criterion.rs]
## Future work
* Experiment with a using a 4x3 matrix as a 3D transform type that can be more
efficient than `Mat4` for certain operations like inverse and multiplies
* `no-std` support
* `wasm` support
## Inspirations
There were many inspirations for the interface and internals of glam from the
Rust and C++ worlds. In particular:
* [How to write a maths library in 2016] inspired the initial `Vec3`
implementation
* [Realtime Math] - header only C++11 with SSE and NEON SIMD intrinsic support
* [DirectXMath] - header only SIMD C++ linear algebra library for use in games
and graphics apps
* `glam` is a play on the name of the popular C++ library `glm`

/*!
# glam
`glam` is a simple and fast linear algebra library for games and graphics.
## Features
`glam` is built with SIMD in mind. Currently only SSE2 on x86/x86_64 is
supported as this is what stable Rust supports.
* Single precision float (`f32`) support only
* SSE2 implementation for most types, including `Mat2`, `Mat3`, `Mat4`, `Quat`,
`Vec3` and `Vec4`
* Scalar fallback implementations exist when SSE2 is not available
* Most functionality includes unit tests and benchmarks
## Linear algebra conventions
`glam` interprets vectors as column matrices (also known as "column vectors")
meaning when transforming a vector with a matrix the matrix goes on the left.
```
use glam::{Mat3, Vec3};
let m = Mat3::identity();
let x = Vec3::unit_x();
let v = m * x;
assert_eq!(v, x);
```
Matrices are stored in memory in column-major order.
Rotations follow left-hand rule. The direction of the axis gives the direction
of rotation: with the left thumb pointing in the positive direction of the axis
the left fingers curl around the axis in the direction of the rotation.
```
use glam::{Mat3, Vec3};
// rotate +x 90 degrees clockwise around y giving -z
let m = Mat3::from_rotation_y(90.0_f32.to_radians());
let v = m * Vec3::unit_x();
assert!(v.abs_diff_eq(-Vec3::unit_z(), core::f32::EPSILON));
```
## Size and alignment of types
Most `glam` types use SIMD for storage meaning most types are 16 byte aligned.
The only exception is Vec2`. When SSE2 is not available on the target
architecture the types will still be 16 byte aligned, so object sizes and
layouts will not change between architectures.
16 byte alignment means that some types will have a stride larger than their
size resulting in some wasted space.
| Type | f32 bytes | SIMD bytes | Wasted bytes |
|:-----|----------:|-----------:|-------------:|
|`Vec3`| 12| 16| 4|
|`Mat3`| 36| 48| 12|
Despite this wasted space the SIMD version tends to outperform the `f32`
implementation in [**mathbench**](https://github.com/bitshifter/mathbench-rs)
benchmarks.
SIMD support can be disabled entirely using the `scalar-math` feature. This
feature will also disable SIMD alignment meaning most types will use native
`f32` alignment of 4 bytes.
All the main `glam` types are tagged with #[repr(C)], so they are possible
to expose as struct members to C interfaces if desired. Be mindful of Vec3's
extra float though.
## Accessing internal data
The SIMD types that `glam` builds on are opaque and their contents are not
directly accessible. Because of this `glam` types uses getter and setter
methods instead of providing direct access.
```
use glam::Vec3;
let mut v = Vec3::new(1.0, 2.0, 3.0);
assert_eq!(v.y(), 2.0);
v.set_z(1.0);
assert_eq!(v.z(), 1.0);
```
If you need to access multiple elements it is easier to convert the type to a
tuple or array:
```
use glam::Vec3;
let v = Vec3::new(1.0, 2.0, 3.0);
let (x, y, z) = v.into();
assert_eq!((x, y, z), (1.0, 2.0, 3.0));
```
## SIMD and scalar consistency
`glam` types implement `serde` `Serialize` and `Deserialize` traits to ensure
that they will serialize and deserialize exactly the same whether or not
SIMD support is being used.
The SIMD versions implement `core::fmt::Display` traits so they print the same as
the scalar version.
```
use glam::Vec3;
let a = Vec3::new(1.0, 2.0, 3.0);
assert_eq!(format!("{}", a), "[1, 2, 3]");
```
## Feature gates
All `glam` dependencies are optional, however some are required for tests
and benchmarks.
* `std` - the default feature, has no dependencies.
* `rand` - used to generate random values. Used in benchmarks.
* `serde` - used for serialization and deserialization of types.
* `mint` - used for interoperating with other linear algebra libraries.
* `scalar-math` - disables SIMD support and uses native alignment for all
types.
* `debug-glam-assert` - adds assertions in debug builds which check the validity
of parameters passed to `glam` to help catch runtime errors.
* `glam-assert` - adds assertions to all builds which check the validity of
parameters passed to `glam` to help catch runtime errors.
