## [0.8.0]
|
|
|
|
|
## Modified
|
|
|
|
|
* Almost everything (types, methods, and traits) now use full names instead
|
|
|
|
|
of abbreviations (e.g. `Vec3` becomes `Vector3`). Most changes are abvious.
|
|
|
|
|
Note however that:
|
|
|
|
|
- `::sqnorm` becomes `::norm_squared`.
|
|
|
|
|
- `::sqdist` becomes `::distance_squared`.
|
|
|
|
|
- `::abs`, `::min`, etc. did not change as this is a common name for
|
|
|
|
|
absolute values on, e.g., the libc.
|
|
|
|
|
- Dynamically sized structures keep the `D` prefix, e.g., `DMat` becomes
|
|
|
|
|
`DMatrix`.
|
|
|
|
|
* All files with abbreviated names have been renamed to their full version,
|
|
|
|
|
e.g., `vec.rs` becomes `vector.rs`.

## [0.7.0]
|
|
|
|
|
### Added
|
|
|
|
|
* Added implementation of assignement operators (+=, -=, etc.) for
|
|
|
|
|
everything.
|
|
|
|
|
### Modified
|
|
|
|
|
* Points and vectors are now linked to each other with associated types
|
2016-04-17 23:26:58 +08:00
|
|
|
(on the PointAsVector trait).

## [0.6.0]
|
|
|
|
|
**Announcement:** a users forum has been created for `nalgebra`, `ncollide`, and `nphysics`. See
|
|
|
|
|
you [there](http://users.nphysics.org)!

### Added
|
2016-04-01 03:46:01 +08:00
|
|
|
* Added a dependency to [generic-array](https://crates.io/crates/generic-array). Feature-gated:
|
|
|
|
|
requires `features="generic_sizes"`.
|
2016-04-17 23:26:58 +08:00
|
|
|
* Added statically sized vectors with user-defined sizes: `VectorN`. Feature-gated: requires
|
2016-04-01 03:46:01 +08:00
|
|
|
`features="generic_sizes"`.
|
|
|
|
|
* Added similarity transformations (an uniform scale followed by a rotation followed by a
|
2016-04-17 23:26:58 +08:00
|
|
|
translation): `Similarity2`, `Similarity3`.
|

|
|
|
|
|
|
|
|
### Removed
|
2016-04-17 23:26:58 +08:00
|
|
|
* Removed zero-sized elements `Vector0`, `Point0`.
|
|
|
|
|
* Removed 4-dimensional transformations `Rotation4` and `Isometry4` (which had an implementation to incomplete to be useful).

### Modified
|
2016-04-01 03:46:01 +08:00
|
|
|
* Vectors are now multipliable with isometries. This will result into a pure rotation (this is how
|
2016-03-25 02:09:32 +08:00
|
|
|
vectors differ from point semantically: they design directions so they are not translatable).
|
2016-04-17 23:26:58 +08:00
|
|
|
* `{Isometry3, Rotation3}::look_at` reimplemented and renamed to `::look_at_rh` and `::look_at_lh` to agree
|
2016-04-01 03:46:01 +08:00
|
|
|
with the computer graphics community (in particular, the GLM library). Use the `::look_at_rh`
|
2016-04-01 03:31:01 +08:00
|
|
|
variant to build a view matrix that
|
|
|
|
|
may be successfully used with `Persp` and `Ortho`.
|
2016-04-17 23:26:58 +08:00
|
|
|
* The old `{Isometry3, Rotation3}::look_at` implementations are now called `::new_observer_frame`.
|
2016-04-01 03:46:01 +08:00
|
|
|
* Rename every `fov` on `Persp` to `fovy`.
|
2016-04-01 03:31:01 +08:00
|
|
|
* Fixed the perspective and orthographic projection matrices.
