Sébastien Crozet 03eda09084 Some documentation fixes.
Fix #25.
2014-10-12 10:35:56 +02:00
Sébastien Crozet b6090042ac Add a `Axpy` that implements y <- y + ax.
This is very useful for accumulations to compute, e.g. centers.
2014-10-12 09:24:16 +02:00
Sébastien Crozet de2479b70f Do not implement `Transform<Vec*> for Vec*`.
This is error prone as this is a no-op for vectors and a translation for points.
2014-10-11 00:23:10 +02:00
Sébastien Crozet 70de340498 Remove the `Iso * Vec` overload and the ability to Transform a Vector with an Iso.
This is too error prone as the user has to remember if he is using a vector or a point.
Istead, to transform a vector with an Isometry, use the internal rotation matrix of the isometry:
`iso.rotation * vector` instead of `iso * vector`.

The `Rotation` trait can also be used.

Sébastien Crozet bf67f079e7 Add a function `nalgebra::center(a, b)` that computes the center of two points. 2014-10-10 21:24:18 +02:00
Sébastien Crozet b3e7540b3c Delete the deprecated `na::` module. 2014-10-10 20:57:20 +02:00
Sébastien Crozet 6fb6d35980 Documentation fixes. 2014-10-10 20:56:40 +02:00
Sébastien Crozet e852eb4783 Fix the implementation of `ToHomogeneous` for `Iso*`. 2014-10-10 20:56:24 +02:00
Sébastien Crozet 7e9bb98823 Add `to_pnt` and `to_vec` methods. 2014-10-10 12:19:37 +02:00
Sébastien Crozet 924d8269d8 Add points.
This adds the Pnt{1,2,3,4,5,6} structures.
This adds the traits:
  − AnyPnt
  − FloatPnt
  − PntExt
  − FloatPntExt
  − Orig (to return the zero point)
  − PntAsVec
  − VecAsPnt
This adds operator overloading:
  − Pnt + Vec
  − Pnt - Vec
  − Pnt * Scalar
  − Pnt / Scalar
  − Pnt + Scalar
  − Pnt - Scalar
  − Iso * Pnt
  − Rot * Pnt
  − Pnt * Iso
  − Pnt * Rot
This changes some behavior:
  − Iso multiplication with a Vec does not translate the vector any more.
  − ToHomogeneous adds a 0.0 at the end of a Vec and a 1.0 at the end of a Pnt.
  − FromHomogeneous performs w-normalization on a Pnt, but not on a Vec.
  − The Translate<Vec> trait is never implemented (i-e. a Vec is not to be translated).

Sébastien Crozet f6c597f102 Update to the last rust-nightly.
Version of rustc: 0.11.0-pre-nightly (faa7ba7 2014-05-31 01:06:40 -0700).

Main changes:
        * `cmp::Ord` -> `cmp::PartialOrd`
        * `cmp::Eq`  ->  `cmp::PartialEq`

Note that `na::PartialOrd` is not the same as `cmp::PartialOrd`
(which lacks a lot of partial ordering operators).

Vincent Barrielle 76a8bc3cf1 QR factorization for fixed size matrices.
The ColSlice implementation for fixed size matrices returns a DVec,
while this is probably not optimal performance-wise, the dynamic nature
of the result makes this necessary. Using a data type presenting the
ImmutableVector trait would solve this, but it looks like a non-trivial
change.

But static matrices can't use it yet, they need to implement the
Row/Col slicing traits.

Vincent Barrielle 6ad11edf9b more generic QR: generalize the impl of the Indexable trait
This allows the implementation of householder reflection without relying
on knowledge of DVec. This required a new member in the Indexable trait:
the shape() function, which returns the maximum index available.

Vincent Barrielle 2fd880a62d implemented QR factorization
this is a first sketch, the algorithm is not yet initialized and relies
on knowledge of DMat internals. A next step would be to implement this
algorithm in a more generic manner.
2014-05-09 18:59:26 +02:00
Sébastien Crozet 9badebf24c Give access to the traits required for generalized operator overloading.
Those are `Vec3MulRhs`-like traits that allow the simulation of haskellish fundeps to allow multiple
overloads of builtin operators (* / + -).
They are all on the `na::overload` module.

2014-04-25 20:28:29 +02:00
Sébastien Crozet 1eed234e08 Avoid name conflicts with the standard lib.
The `Vec` trait is renamed `AnyVec`.
The `Less`, `Greater`, `Equal` variants are renamed `PartialLess`, `PartialGreater`,
`PartialEqual`.

Those new names are not very good, so they might change in the future.

2013-10-17 22:40:44 +02:00
Sébastien Crozet 90e40aaec0 Make most out-of-place methods static.
This is to make people prefer the functional style.
Things like `a.dot(b)` dont make sense per se (there is no reason for `a` to have a different
status than `b`). Using static methods avoid this.

In-place methods are left unchanged.
2013-10-16 21:44:33 +02:00
Sébastien Crozet dcd1e7719b Add methods to access a DVec<N> as a &[N]. 2013-10-14 15:38:23 +02:00
Sébastien Crozet bb5654d220 Remove free-functions alliasing structures constructors.
Those constructors are not idiomatic. Use e.g. `Vec3::new(0, 0, 0)` instead.
2013-10-14 11:22:38 +02:00
Sébastien Crozet ccbc8b4429 Api change: deal with inplace/out of place methods.
Before, it was too easy to use an out of place method instead of the inplace one since they name
were pretty mutch the same. This kind of confusion may lead to silly bugs very hard to understand.
Thus the following changes have been made when a method is available both inplace and out-of-place:

* inplace version keep a short name.
* out-of-place version are suffixed by `_cpy` (meaning `copy`), and are static methods.

Methods applying transformations (rotation, translation or general transform) are now prefixed by
`append`, and a `prepend` version is available too.

Also, free functions doing in-place modifications dont really make sense. They have been removed.

Here are the naming changes:
* `invert` -> `inv`
* `inverted` -> `Inv::inv_cpy`
* `transpose` -> `transpose`
* `transposed` -> `Transpose::transpose_cpy`
* `transform_by` -> `append_transformation`
* `transformed` -> `Transform::append_transformation_cpy`
* `rotate_by` -> `apppend_rotation`
* `rotated` -> `Rotation::append_rotation_cpy`
* `translate_by` -> `apppend_translation`
* `translate` -> `Translation::append_translation_cpy`
* `normalized` -> `Norm::normalize_cpy`
* `rotated_wrt_point` -> `RotationWithTranslation::append_rotation_wrt_point_cpy`
* `rotated_wrt_center` -> `RotationWithTranslation::append_rotation_wrt_center_cpy`

Note that using those static methods is very verbose, and using in-place methods require an
explicit import of the related trait.

This is a way to convince the user to use free functions most of the time.
2013-10-14 10:42:07 +02:00
Sébastien Crozet 20bdbb6408 Dont re-export std::num::{Zero, One}.

Sébastien Crozet 84212f1449 Huge api change!
Everything changed, hopefully for the best.

* everything is accessible from the `na` module. It re-export
  everything and provides free functions (i-e: na::dot(a, b) instead of
  a.dot(b)) for most functionalities.
* matrix/vector adaptors (Rotmat, Transform) are replaced by plain
  types: Rot{2, 3, 4} for rotation matrices and Iso{2, 3, 4} for
  isometries (rotation + translation).  This old adaptors system was to
  hard to understand and to document.
* each file related to data structures moved to the `structs` folder.
  This makes the doc a lot more readable and make people prefer the
  `na` module instead of individual small modules.
* Because `na` exists now, the modules `structs::vec` and
  `structs::mat` dont re-export anything now.

As a side effect, this makes the documentation more readable.
2013-10-06 18:07:17 +02:00

Sébastien Crozet 7de844b46a Moved some files + use rustdoc_ng to generate the documenatiton.
Trait failes are merged in three files:
    * operations.rs - for low-level matrix/vector operations
    * geometry.rs   - for operations with a clear, broadly known geometric meaning.
    * structure.rs  - for operations to access/alter the object inner structures.

Specialisations are moved to the `spec` folder.

limitations of rust traits system).
2013-09-15 11:18:06 +02:00
Sébastien Crozet 514bf74efe "Replaced" Scalar{Add, Sub, Mul, Div} by operator overloading.
Those traits are not really removed since rust cannot handle those multiple operator overloading
very well yet, making them sometimes unuseable on generic code.
2013-09-14 21:32:38 +02:00
Sébastien Crozet e3a1d56e58 Set up the hack to allow better overloads of the Mul trait.

2013-08-31 11:41:32 +02:00
Sébastien Crozet eb4e4a6aeb Add a PVec3 type, for Padded Vector 3d.
This is the same as Vec3 but with an extra field for padding. This is useful for applications
needing a power-of-two number of arguments (typically mixed CPU/GPU applications).

The corresponding matrix is not yet implemented.
2013-08-31 11:13:17 +02:00
Sébastien Crozet 346a803b7f Improve how the dummy parameter are passed to the Dim::dim function. 2013-08-30 09:53:17 +02:00
Sébastien Crozet 82ddda154f Update to work with the last compiler.
Because of the unfortunate changes on type parameters resolution:
        - the Dim trait now needs an useless parameter to infer the Self type.
        - ApproxEps::epsilon() is broken.
2013-08-28 14:22:12 +02:00

2013-08-23 15:59:26 +02:00
Sébastien Crozet 6999444575 Merge the Rotatable, Translatable, Transformable traits with their corresponding Rotation, Translation, Transformation. 2013-08-22 17:47:37 +02:00
Sébastien Crozet 347883caa1 Rework of the traits for Vectors.
The goal is to make traits less fine-grained for vectors, and reduce the amount of `use`.

- Scalar{Mul, Div} are removed, replaced by Mul<N, V> and Div<N, V>,
- Ring and DivisionRing are removed. Use Num instead.
- VectorSpace, Dot, and Norm are removed, replaced by the new, higher-level traits.

Add four traits:
- Vec: common operations on vectors. Replaces VectorSpace and Dot.
- AlgebraicVec: Vec + the old Norm trait.
- VecExt: Vec + every other traits vectors implement.
- AlgebraicVecExt: AlgebraicVec + VecExt.
2013-08-18 18:33:25 +02:00

Sébastien Crozet 93597f0ef9 Add look_at_z.
Having a look_at which aligns the z-axis with the look_at direction is useful for cameras. It
will exist only in 3d.
2013-07-23 18:41:57 +02:00
Sébastien Crozet 8634b9037d Changed the semantic of the look_at method.
Before, the `look_at` method aligned the `z` axis with the look_at direction.
This will be problematic in the future if we want to generalize that on n-dimension (the z axis
could not axis at all when n < 3).
Now, the `look_at` method aligns the `x` axis with the look_at direction. Thus we have a chance for
it to be generalizable on n-dimension, `n >= 1`.

Sébastien Crozet cf216f9b90 Removed occurences of copy/Copy + improved api.
Now, access to vector components are x, y, z, w, a, b, ... instead of at[i].
The method at(i) has the same (read only) effect as the old at[i].

Now, access to matrix components are m11, m12, ... instead of mij[offset(i, j)]...
The method at((i, j)) has the same effect as the old mij[offset(i, j)].

Automatic implementation of all traits the compiler supports has been added on the #[deriving]
clause for both matrices and vectors.
