To be specific, support is added for `N op T<N>` where `N` is `f32` or `f64`,
`op` is one of `+` `-` `*`, and `T` is one of the `Vec`, `DVec`, `Mat`, or `DMat`
generic types. These are all cases where `T<N> op N` is already supported.
Rust does not support generic impls in this case, but `f32` and `f64` cover
many common cases.
Fixes#182.
Use associated types for the `Outer` trait.
Add a `Repeat` trait for constructing a multidimensional value by repeating an element.
Split the `Diag` trait into `Diag` and `DiagMut`.
Implement `RustEncodable` for `Identity`.
Mostly related to the `us` → `usize` suffix renaming. It turns out that none of
the suffixes are required any more, as the type inference appears to have
improved in that regard. There were also parantheses around range terms that
are not required any more.
Finally the `[]` syntax has been deprecated and thereby removed.
Fixes#52.
This renames pairs of methods like `normalize_cpy`, `normalize` to `normalize`
and `normalize_mut`. Note that the previous in-place operations had the same
name that now belongs to the copy operations. Therefore this is a breaking
change.
On a similar note, the `Quat::conjugate` method was also renamed to
`conjugate_mut` and a new copying method has taken its place. This appears to
be a similar issue (apart from the lack of the copy operation) and thus was
dealt with here, too.
approx_eq_ulps() allows specification of epsilon as an integer number
of Units in the Last Place (ULPs) difference between the two floating
point values
default approx_ulps() is set to 8.
approx_eq() function continues to use epsilon method, although I
recommend further commits and a migration towards the ULPs method.
Wherever sensible the geometric traits now take `&self` arguments, so that
implementations can be invoked as instance methods instead of static methods.
This makes some idioms easier to express and generally allows for greater
flexibility as the restructured methods can still be invoked like static
methods.
Fixes#39.
This is just a quick-fix so that nalgebra compiles.
This does not fix the deprecation warnings!
Version of rustc: 0.13.0-nightly (d91a015ab 2014-11-14 23:37:27 +0000).
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.
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).
