# Change Log All notable changes to this project will be documented in this file, following the format defined at [keepachangelog.com](http://keepachangelog.com/). This project adheres to [Semantic Versioning](http://semver.org/). ## [Unreleased] ### Added - Implements `fmt::Debug` for `Basis2`, `Basis3`, and `AffineMatrix3` - A `prelude` module for easy importing of common traits. ### Changed - Improves the `fmt::Debug` impls for `Vector`, `Matrix`, `Point`, `Decomposed`, `Quaternion` and `Angle` to make them easier to derive, and have clearer formatting. - Marks vectors, points, matrices, and angles as `#[repr(C, packed)]`. - Renames the `Vector::{length, length2}` functions to `Vector::{magnitude, magnitude2}`. ## [v0.7.0] - 2015-12-23 ### Added - Add missing by-ref and by-val permutations of `Vector`, `Matrix`, `Point`, `Quaternion` and `Angle` operators. - Ease lifetime constraints by removing `'static` from some scalar type parameters. - Weaken type constraints on `perspective` function to take an `Into>`. - Add `Angle::new` for constructing angles from a unitless scalar. - Implement assignment operators for nightly builds, enabled by the `"unstable"` feature. ### Changed - `Vector`, `Matrix`, `Point`, and `Angle` are now constrained to require specific operators to be overloaded. This means that generic code can now use operators, instead of the operator methods. - Take a `Rad` for `ProjectionFov::fovy`, rather than arbitrary `Angle`s. This simplifies the signature of `PerspectiveFov` from `PerspectiveFov` to `PerspectiveFov`. - The following trait constraints were removed from `Angle`: `Debug`, `ScalarConv`, `Into>`, `Into>`. - `Angle` no longer requires `One`, and the implementations have been removed from `Deg` and `Rad`. This is because angles do not close over multiplication, and therefore cannot have a multiplicative identity. If we were truly accurate, `Angle * Angle` would return an `Angle^2` (not supported by the current api). - Make remainder operators on `Angle`s make sense from the perspective of dimensional analysis. - Moved free trigonometric functions onto `Angle`. ### Removed - Remove redundant `Point::{min, max}` methods - these are now covered by the `Array::{min, max}` methods that were introduced in 0.5.0. - Removed `ToComponents`, `ToComponents2`, and `ToComponents3`. If you were relying on `ToComponents::decompose`, you can produce the same effect by accessing the fields on `Decomposed` directly. To create the scale vector, use: `Vector::from_value(transform.scale)`. - Removed `CompositeTransform`, `CompositeTransform2`, and `CompositeTransform3`. - Remove `Vector::one`. Vectors don't really have a multiplicative identity. If you really want a `one` vector, you can do something like: `Vector::from_value(1.0)`. - Remove operator methods from `Vector`, `Matrix`, `Point`, and `Angle` traits in favor of operator overloading. - Remove `*_self` methods from `Vector`, `Matrix`, `Point`, and `Angle`. The operator methods can be used via the unstable assignment operators. - Remove `#[derive(Hash)]` from `Deg` and `Rad`. This could never really be used these types, because they expect to be given a `BaseFloat` under normal circumstances. ## [v0.6.0] - 2015-12-12 ### Added - This CHANGELOG for keeping track of notable changes. - `Matrix4::{from_scale, from_nonuniform_scale}` for easily constructing homogeneous scale matrices. ### Changed - Renamed `SquareMatrix::one` to `SquareMatrix::identity`. `identity` is easier to search for, and the more common name for the multiplicative identity for matrices. - Matrix impls have now been constrained to `S: BaseFloat`. ## [v0.5.0] - 2015-11-20 ### Changed - Take many point and vector parameters by value. - Take point and vector operator overloads by value. - Divide `Matrix` trait into `Matrix` and `SquareMatrix`, opening the door for non-square matrices in the future. - Make many trait type parameters associated types. - Move element-wise methods from `Vector` and `Point` onto the `Array1` trait, and rename it to `Array`. - Make pointer access methods on `Array` match the naming scheme of those in the standard library. ### Removed - Removed collision types: `Ray`, `Plane`, `Frustum`, `Aabb2`, `Aabb3` `Obb2`, `Obb3` `Sphere`, `Cylinder`. These can now be found at [csherratt/collision-rs](https://github.com/csherratt/collision-rs). - Remove `Array2` trait, moving methods onto the `Matrix` trait. ## [v0.4.0] - 2015-10-25 ## [v0.3.1] - 2015-09-20 ## [v0.3.0] - 2015-09-20 ## [v0.2.0] - 2015-05-11 ## [v0.1.6] - 2015-05-10 ## [v0.1.5] - 2015-04-25 ## [v0.1.4] - 2015-04-24 ## [v0.1.3] - 2015-04-06 ## [v0.1.2] - 2015-04-01 ## [v0.1.1] - 2015-03-25 ## [v0.1.0] - 2015-03-15 ## [v0.0.8] - 2015-03-09 ## [v0.0.7] - 2015-03-01 ## [v0.0.6] - 2015-02-21 ## [v0.0.5] - 2015-02-16 ## [v0.0.4] - 2015-02-11 ## [v0.0.3] - 2015-02-08 ## v0.0.1 - 2014-06-24 [Unreleased]: https://github.com/bjz/cgmath/compare/v0.7.0...HEAD [v0.7.0]: https://github.com/bjz/cgmath/compare/v0.6.0...v0.7.0 [v0.6.0]: https://github.com/bjz/cgmath/compare/v0.5.0...v0.6.0 [v0.5.0]: https://github.com/bjz/cgmath/compare/v0.4.0...v0.5.0 [v0.4.0]: https://github.com/bjz/cgmath/compare/v0.3.1...v0.4.0 [v0.3.1]: https://github.com/bjz/cgmath/compare/v0.3.0...v0.3.1 [v0.3.0]: https://github.com/bjz/cgmath/compare/v0.2.0...v0.3.0 [v0.2.0]: https://github.com/bjz/cgmath/compare/v0.1.6...v0.2.0 [v0.1.6]: https://github.com/bjz/cgmath/compare/v0.1.5...v0.1.6 [v0.1.5]: https://github.com/bjz/cgmath/compare/v0.1.4...v0.1.5 [v0.1.4]: https://github.com/bjz/cgmath/compare/v0.1.3...v0.1.4 [v0.1.3]: https://github.com/bjz/cgmath/compare/v0.1.2...v0.1.3 [v0.1.2]: https://github.com/bjz/cgmath/compare/v0.1.1...v0.1.2 [v0.1.1]: https://github.com/bjz/cgmath/compare/v0.1.0...v0.1.1 [v0.1.0]: https://github.com/bjz/cgmath/compare/v0.0.8...v0.1.0 [v0.0.8]: https://github.com/bjz/cgmath/compare/v0.0.7...v0.0.8 [v0.0.7]: https://github.com/bjz/cgmath/compare/v0.0.6...v0.0.7 [v0.0.6]: https://github.com/bjz/cgmath/compare/v0.0.5...v0.0.6 [v0.0.5]: https://github.com/bjz/cgmath/compare/v0.0.4...v0.0.5 [v0.0.4]: https://github.com/bjz/cgmath/compare/v0.0.3...v0.0.4 [v0.0.3]: https://github.com/bjz/cgmath/compare/v0.0.1...v0.0.3
