Change Log

All notable changes to this project will be documented in this file, following the format defined at keepachangelog.com. This project adheres to Semantic Versioning.

Unreleased

Added

• Implements fmt::Debug for Basis2, Basis3, and AffineMatrix3
• A prelude module for easy importing of common traits.
• Constrained conversion functions for assisting in situations where type inference is difficult.
• An ElementWise trait for non-mathematical element-wise operations.

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}.

Removed

• The non-mathematical operator trait implementations have been removed from the Vector trait, in favor of the ElementWise trait.

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<Rad<S>>.
• 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 Angles. This simplifies the signature of PerspectiveFov from PerspectiveFov<S, A> to PerspectiveFov<S>.
• The following trait constraints were removed from Angle: Debug, ScalarConv, Into<Rad<S>>, Into<Deg<S>>.
• 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 Angles 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.
• Remove Array2 trait, moving methods onto the Matrix trait.
