d8dfedbf99 Update to the last rust-nightly.

77348f668f Use our own traits instead of the deprecated ones. 
We might switch to bjz/num-rs eventually (#32), but in the mean time we just re-declare the
deprecrated traits in nalgebra.

39b9d20717 Quick update to the last rust-nightly. 
This is just a quick-fix so that nalgebra compiles.
This does not fix the deprecation warnings!

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.

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
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).

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).

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.
