This project adheres to [Semantic Versioning](http://semver.org/).
|
||||
|
||||
## [0.11.0]
|
||||
The [website](http://nalgebra.org) has been fully rewritten and gives a good
|
||||
overview of all the added/modified features.
|
||||
|
||||
This version is a major rewrite of the library. Major changes are:
|
||||
* Algebraic traits are now defined by the [alga](https://crates.io/crates/alga) crate.
|
||||
* Methods are now preferred to free functions because they do not require any
|
||||
trait to be used any more.
|
||||
* Most algebraic entities can be parametrized by type-level integers
|
||||
to specify their dimensions. Using `Dynamic` instead of a type-level
|
||||
integer indicates that the dimension known at run-time only.
|
||||
* Statically-sized **rectangular** matrices.
|
||||
* More transformation types have been added: unit-sized complex numbers (for
|
||||
2D rotations), affine/projective/general transformations with `Affine2/3`,
|
||||
`Projective2/3`, and `Transform2/3`.
|
||||
* Serde serialization is now supported instead of `rustc_serialize`.
|
||||
* Matrix **slices** are now implemented.
|
||||
|
||||
### Added
|
||||
Lots of features including rectangular matrices, slices, and Serde
|
||||
serialization. Refer to the brand new [website](http://nalgebra.org) for more
|
||||
details. The following free-functions have been added as well:
|
||||
* `::id()` that returns the universal [identity element](http://nalgebra.org/performance_tricks/#the-id-type)
|
||||
of type `Id`.
|
||||
* `::inf_sup()` that returns both the infimum and supremum of a value at the
|
||||
same time.
|
||||
* `::partial_sort2()` that attempts to sort two values in increasing order.
|
||||
* `::wrap()` that moves a value to the given interval by adding or removing
|
||||
the interval width to it.
|
||||
|
||||
### Modified
|
||||
* `::cast` -> `::convert`
|
||||
* `point.as_vector()` -> `point.coords`
|
||||
* `na::origin` -> `P::origin()`
|
||||
* `na::is_zero` -> `.is_zero()` (from num::Zero)
|
||||
* `.transform` -> `.transform_point`/`.transform_vector`
|
||||
* `.translate` -> `.translate_point`
|
||||
* `::dimension::<P>` -> `::dimension::<P::Vector>`
|
||||
* `::angle_between` -> `::angle`
|
||||
|
||||
The following free-functions are now replaced by methods (with the same names)
|
||||
only:
|
||||
`::cross`, `::cholesky`, `::determinant`, `::diagonal`, `::eigen_qr` (becomes
|
||||
`.eig`), `::hessenberg`, `::qr`, `::to_homogeneous`, `::to_rotation_matrix`,
|
||||
`::transpose`, `::shape`.
|
||||
|
||||
|
||||
The following free-functions are now replaced by static methods only:
|
||||
* `::householder_matrix` under the name `::new_householder_generic`
|
||||
* `::identity`
|
||||
* `::new_identity` under the name `::identity`
|
||||
* `::from_homogeneous`
|
||||
* `::repeat` under the name `::from_element`
|
||||
|
||||
The following free-function are now replaced methods accessible through traits
|
||||
only:
|
||||
* `::transform` -> methods `.transform_point` and `.transform_vector` of the `alga::linear::Transformation` trait.
|
||||
* `::inverse_transform` -> methods `.inverse_transform_point` and
|
||||
`.inverse_transform_vector` of the `alga::linear::ProjectiveTransformation`
|
||||
trait.
|
||||
* `::translate`, `::inverse_translate`, `::rotate`, `::inverse_rotate` ->
|
||||
methods from the `alga::linear::Similarity` trait instead. Those have the
|
||||
same names but end with `_point` or `_vector`, e.g., `.translate_point` and
|
||||
`.translate_vector`.
|
||||
* `::orthonormal_subspace_basis` -> method with the same name from
|
||||
`alga::linear::FiniteDimInnerSpace`.
|
||||
* `::canonical_basis_element` and `::canonical_basis` -> methods with the
|
||||
same names from `alga::linear::FiniteDimVectorSpace`.
|
||||
* `::rotation_between` -> method with the same name from the
|
||||
`alga::linear::Rotation` trait.
|
||||
* `::is_zero` -> method with the same name from `num::Zero`.
|
||||
|
||||
|
||||
|
||||
### Removed
|
||||
* The free functions `::prepend_rotation`, `::append_rotation`,
|
||||
`::append_rotation_wrt_center`, `::append_rotation_wrt_point`,
|
||||
`::append_transformation`, and `::append_translation ` have been removed.
|
||||
Instead create the rotation or translation object explicitly and use
|
||||
multiplication to compose it with anything else.
|
||||
|
||||
* The free function `::outer` has been removed. Use column-vector ×
|
||||
row-vector multiplication instead.
|
||||
|
||||
* `::approx_eq`, `::approx_eq_eps` have been removed. Use the `relative_eq!`
|
||||
macro from the [approx](https://crates.io/crates/approx) crate instead.
|
||||
|
||||
* `::covariance` has been removed. There is no replacement for now.
|
||||
* `::mean` has been removed. There is no replacement for now.
|
||||
* `::sample_sphere` has been removed. There is no replacement for now.
|
||||
* `::cross_matrix` has been removed. There is no replacement for now.
|
||||
* `::absolute_rotate` has been removed. There is no replacement for now.
|
||||
* `::rotation`, `::transformation`, `::translation`, `::inverse_rotation`,
|
||||
`::inverse_transformation`, `::inverse_translation` have been removed. Use
|
||||
the appropriate methods/field of each transformation type, e.g.,
|
||||
`rotation.angle()` and `rotation.axis()`.
|
||||
|
||||
## [0.10.0]
