# Change Log
|
|
All notable changes to `nalgebra`, starting with the version 0.6.0 will be
|
|
documented here.
|
|
|
|
This project adheres to [Semantic Versioning](http://semver.org/).
|
|
|
|
## [0.6.0]
|
|
**Announcement:** a users forum has been created for `nalgebra`, `ncollide`, and `nphysics`. See
|
|
you [there](http://users.nphysics.org)!
|
|
|
|
### Added
|
|
* Added a dependency to [generic-array](https://crates.io/crates/generic-array). Feature-gated:
|
|
requires `features="generic_sizes"`.
|
|
* Added statically sized vectors with user-defined sizes: `VecN`. Feature-gated: requires
|
|
`features="generic_sizes"`.
|
|
* Added similarity transformations (an uniform scale followed by a rotation followed by a
|
|
translation): `Sim2`, `Sim3`.
|
|
|
|
### Removed
|
|
* Removed zero-sized elements `Vec0`, `Pnt0`.
|
|
* Removed 4-dimensional transformations `Rot4` and `Iso4` (which had an implementation to incomplete to be useful).
|
|
|
|
### Modified
|
|
* Vectors are now multipliable with isometries. This will result into a pure rotation (this is how
|
|
vectors differ from point semantically: they design directions so they are not translatable).
|
|
* `{Iso3, Rot3}::look_at` reimplemented and renamed to `::look_at_rh` and `::look_at_lh` to agree
|
|
with the computer graphics community (in particular, the GLM library). Use the `::look_at_rh`
|
|
variant to build a view matrix that
|
|
may be successfully used with `Persp` and `Ortho`.
|
|
* The old `{Iso3, Rot3}::look_at` implementations are now called `::new_observer_frame`.
|
|
* Rename every `fov` on `Persp` to `fovy`.
|
|
* Fixed the perspective and orthographic projection matrices.
