Change Log

All notable changes to nalgebra, starting with the version 0.6.0 will be documented here.

This project adheres to Semantic Versioning.

[0.7.0]

Points and vectors are now linked to each other with associated types (on the PntAsVec trait).

Announcement: a users forum has been created for nalgebra, ncollide, and nphysics. See you there!

Added a dependency to generic-array. Feature-gated: requires features="generic_sizes".
Added statically sized vectors with user-defined sizes: VecN. Feature-gated: requires features="generic_sizes".
Added similarity transformations (an uniform scale followed by a rotation followed by a translation): Sim2, Sim3.

Removed zero-sized elements Vec0, Pnt0.
Removed 4-dimensional transformations Rot4 and Iso4 (which had an implementation to incomplete to be useful).

Vectors are now multipliable with isometries. This will result into a pure rotation (this is how vectors differ from point semantically: they design directions so they are not translatable).
{Iso3, Rot3}::look_at reimplemented and renamed to ::look_at_rh and ::look_at_lh to agree with the computer graphics community (in particular, the GLM library). Use the ::look_at_rh variant to build a view matrix that may be successfully used with Persp and Ortho.
The old {Iso3, Rot3}::look_at implementations are now called ::new_observer_frame.
Rename every fov on Persp to fovy.
Fixed the perspective and orthographic projection matrices.
