|
|
|
|
## [v0.10.0] - 2016-05-11
|
|
|
|
### Added
|
|
|
|
- A `MetricSpace` trait for types that have a distance between elements.
|
|
- `EuclideanSpace::{midpoint, centroid}` functions with default
|
|
implementations.
|
|
- `Vector1` and `Point1` structs.
|
|
- Serde support behind the `eders` feature flag.
|
|
- An `ApproxEq` implementation for `Decomposed`.
|
|
|
|
### Changed
|
|
|
|
- Depend on the `num-traits` crate rather than `num`, seeing as we only use the
|
|
traits in `num`. `num_traits` has also been re-exported so that you can more
|
|
easily use these in your project.
|
|
- Use an `Euler` type for euler angle conversions.
|
|
- Constrain `InnerSpace` by `MetricSpace`.
|
|
- Constrain `Rotation` by `One`
|
|
- Implement `Transform` and `Transform3` for `Matrix4`.
|
|
- Implement `Transform`, `Transform2`, and `Transform3` for `Matrix4`.
|
|
- Fix `Euler`-`Quaternion` and `Quaternion`-`Euler` conversions. The axes are
|
|
now correct, and the angles are applied in _x_-_y_-_z_ order. The conversion now
|
|
matches the conversion from axis angle.
|
|
- Fix `Euler`-`{Matrix3, Matrix4}` conversions.
|
|
|
|
## Removed
|
|
|
|
- `Rotation::transform_as_point`
|
|
- `AffineMatrix3`
|
|
- `Rotation::invert_self`
|
|
- `Matrix::invert_self`
|
|
|
|
## [v0.9.1] - 2016-04-20
|
|
|
|
### Changed
|
|
|
|
- Fix angle assignment operators so that they actually mutate `self`.
|
|
|
|
## [v0.9.0] - 2016-04-19
|
|
|
|
### Changed
|
|
|
|
- Assignment operators implementations have been stabilised, to coincide with
|
|
their [stabilisation in Rust 1.8](http://blog.rust-lang.org/2016/04/14/Rust-1.8.html).
|
|
- Renames `Vector` trait to `VectorSpace`.
|
|
- Renames `EuclideanVector` to `InnerSpace`.
|
|
- Renames `Point` to `EuclideanSpace`, and `Point::Vector` to `EuclideanSpace::Diff`.
|
|
- `Quaternion`s now implement `VectorSpace` and `InnerSpace` for the functions
|
|
they share.
|
|
- The `Matrix` trait is now constraint by `VectorSpace`, with `Matrix::Element`
|
|
removed in favor of `VectorSpace::Scalar`.
|
|
|
|
## [v0.8.0] - 2016-04-06
|
|
|
|
### 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.
|
|
- A default implementation for `EuclideanVector::angle`.
|
|
|
|
### 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}`.
|
|
- Move `Angle::new` to be directly implemented on the `Rad` and `Deg` types.
|
|
- Move `Vector::dot` to `EuclideanVector` trait.
|
|
- Move `Vector::from_value` to `Array` trait.
|
|
|
|
### Removed
|
|
|
|
- The non-mathematical operator trait implementations have been removed from
|
|
the `Vector` trait, in favor of the `ElementWise` trait.
|
|
- `Angle::equiv`.
|
|
- Remove `neg_self` method on vectors and matrices.
|
|
|
|
## [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 `Angle`s. 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 `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.
