Change Log

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

This project adheres to Semantic Versioning.

[0.9.0] - WIP

Modified

• Renamed:
  • ::from_col_vector -> ::from_column_vector
  • ::from_col_iter -> ::from_column_iter
  • .col_slice -> .column_slice
  • .set_col -> .set_column
  • ::canonical_basis_with_dim -> ::canonical_basis_with_dimension
  • ::from_elem -> ::from_element
• Added:
  • Added .exp() and .pow() for quaternions.

[0.8.0]

Modified

• Almost everything (types, methods, and traits) now use full names instead of abbreviations (e.g. Vec3 becomes Vector3). Most changes are abvious. Note however that:
  • ::sqnorm becomes ::norm_squared.
  • ::sqdist becomes ::distance_squared.
  • ::abs, ::min, etc. did not change as this is a common name for absolute values on, e.g., the libc.
  • Dynamically sized structures keep the D prefix, e.g., DMat becomes DMatrix.
• All files with abbreviated names have been renamed to their full version, e.g., vec.rs becomes vector.rs.

[0.7.0]

Added

• Added implementation of assignement operators (+=, -=, etc.) for everything.

Modified

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

[0.6.0]

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

Added

• Added a dependency to generic-array. Feature-gated: requires features="generic_sizes".
• Added statically sized vectors with user-defined sizes: VectorN. Feature-gated: requires features="generic_sizes".
• Added similarity transformations (an uniform scale followed by a rotation followed by a translation): Similarity2, Similarity3.

Removed

• Removed zero-sized elements Vector0, Point0.
• Removed 4-dimensional transformations Rotation4 and Isometry4 (which had an implementation to incomplete to be useful).

Modified

• 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).
• {Isometry3, Rotation3}::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 {Isometry3, Rotation3}::look_at implementations are now called ::new_observer_frame.
• Rename every fov on Persp to fovy.
• Fixed the perspective and orthographic projection matrices.
