Sébastien Crozet 8423286911 Switch to column-major representation.
Matrices are now column-major.
This will be useful to interop with opengl and lapack.

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.

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.

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.

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.

Sébastien Crozet d4ee651305 Move the Basis trait inheritance from VecExt to AlgebraicVecExt.

Sébastien Crozet d12d23d2c7 Add the doc folder to the .gitignore. 2013-09-22 11:09:32 +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.

Sébastien Crozet 6dc8139794 "Remove" the RMul and LMul trait. Use the regular Mul trait.
Those traits are not really removed since they are useful on generic code (to work around curret
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.
