6b4b25acd4 Basis: add a method to compute the i-th element of the canonical basis. 2014-10-30 09:21:20 +01:00

171576e2a0 Move the eigen_qr function behind the EigenQR trait. 
This simplifies generic programming.

27be1f0651 Add a SquareMat trait for square matrices. 2014-10-30 09:21:20 +01:00

6a194b2b62 Rename: Any{Vec,Pnt} to Num{Vec,Pnt} + do not impl them automatically. 
Instead, implement them manually. This clarifies error messages for the users.

a0fffe93a9 Move the .shape() method to its own trait: Shape. 2014-10-30 09:21:18 +01:00

3354ffc37b Make FloatPnt and FloatVec derive from Index. 
The point it that `Index` provides the i-th element decomposed into the trivial basis of their
associated vector spaces.

2b23446d54 Matrix Index/IndexMut implementation: return an element instead of a column. 
There is no reason why indexing would prefer returning a column instead of a line. Instead, we
return an element, and let the user use the `Col` and `Row` traits istead.

eb24c4063f Remove the {Any,Float}{Pnt,Vec}Ext traits. 
They are meaningless and too hard to implement in an ad-hoc way to be really useful.

074c9356bf Rename: PartialOrd -> POrd, PartialOrdering -> POrdering. 
This avoids name clashes with the standard library.

a960afa4f9 Make AnyVec inherit from Basis. 
Every vector must have a basis.

e2fc8aa764 Deprecate to_pnt, as_pnt and VecAsPnt. 
Those are meaningless. Use `na::orig() + the_vector` instead.

276bf3f999 Update to the last rust-nightly.

b6090042ac Add a Axpy that implements y <- y + ax. 
This is very useful for accumulations to compute, e.g. centers.

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.

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.

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).
