• v0.30.1 Changes

  January 09, 2022

  ➕ Added

  • ➕ Add conversion from/to types of glam 0.19 and 0.20.

• v0.30.0 Changes

  January 02, 2022

  💥 Breaking changes

  • The Dim trait is now marked as unsafe.
  • The Matrix::pow and Matrix::pow_mut methods only allow positive integer exponents now. To compute negative exponents, the user is free to invert the matrix before calling pow with the exponent’s absolute value.
  • ✂ Remove the Bounded requirement from RealField. Replace it by methods returning Option<Self> so that they can still be implemented by unbounded types (by returning None).
  • The ComplexField trait derives from FromPrimitive again. We can actually keep this because all its methods return Option<Self>, meaning that it could be implemented by any type.

  Modified

  • 👉 Use more concise debug impls for matrices and geometric transformation types.
  • 0️⃣ The singular values computed by the SVD are now sorted in increasing order by default. Use SVD::new_unordered instead to reproduce the older behavior without the sorting overhead.
  • The UnitDualQuaternion::sclerp method will no longer panic when given two equal rotations.
  • The Matrix::select_rows and Matrix::select_columns methods no longer require the matrix components to implement the trait Zero.
  • The Matrix::pow and Matrix::pow_mut methods will now also work with integer matrices.

  ➕ Added

  • Added the conversion trait From<Vec<T>> and method from_vec_storage for RowDVector.
  • ➕ Added implementation of From and Into for converting between nalgebra types and types from glam 0.18. These can be enabled by enabling the convert-glam018 cargo features.
  • Added the methods Matrix::product, ::row_product, ::row_product_tr, and ::column_product to compute the product of the components, rows, or columns, of a single matrix or vector.
  • 0️⃣ The Default trait is now implemented for most geometric types: Point, Isometry, Rotation, Similarity, Transform, UnitComplex, and UnitQuaternion.
  • ➕ Added the Scale geometric type for representing non-uniform scaling.
  • Added Cholesky::new_with_substitute that will replace diagonal elements by a given constant whenever Cholesky meets a non-definite-positiveness.
  • Re-added the conversion from a vector/matrix slice to a static array.
  • ➕ Added the cuda feature that enables the support of rust-cuda for using nalgebra features with CUDA kernels written in Rust.
  • ➕ Added special-cases implementations for the 2x2 and 3x3 SVDs for better accuracy and performances.
  • Added the methods Matrix::polar, Matrix::try_polar, and SVD::to_polar to compute the polar decomposition of a matrix, based on its SVD.
  • 📜 nalgebra-sparse: provide constructors for unsorted but otherwise valid data using the CSR format.
  • 📜 nalgebra-sparse: added reading MatrixMarked data files to a sparse CooMatrix.

  🛠 Fixed

  • 🛠 Fixed a potential unsoundness with matrix.get(i) and matrix.get_mut(i) where i is an usize, and matrix is a matrix slice with non-default strides.
  • 🛠 Fixed potential unsoundness with vector.perp where vector isn’t actually a 2D vector as expected.
  • 🛠 Fixed linkage issue with nalgebra-lapack: the user of nalgebra-lapack no longer have to add extern crate lapack-src to their main.rs.
  • 🛠 Fixed the no-std build of nalgebra-glm.
  • 🛠 Fix the pow and pow_mut functions (the result was incorrect for some exponent values).

• v0.29.1 Changes

  ➕ Added

  • The conversion trait From<Vec<T>> and method from_vec_storage for RowDVector. See #975
  • ➕ Added implementation of From and Into for converting between nalgebra types and types from glam 0.18. These can be enabled by enabling the convert-glam018 cargo features.
  • Added the methods Matrix::product, ::row_product, ::row_product_tr, and ::column_product to compute the product of the components, rows, or columns, of a single matrix or vector.
  • 0️⃣ The Default trait is now implemented for most geometric types: Point, Isometry, Rotation, Similarity, Transform, UnitComplex, and UnitQuaternion.

• v0.29.0 Changes

  💥 Breaking changes

  • ⚡️ We updated to the version 0.6 of simba. This means that the trait bounds T: na::RealField, na::ComplexField, na::SimdRealField, na:SimdComplexField no imply that T: Copy (they only imply that T: Clone). This may affect generic code.
  • The closure given to apply, zip_apply, zip_zip_apply must now modify the first argument inplace, instead of returning a new value. This makes these methods more versatile, and avoid useless clones when using non-Copy scalar types.
  • The Allocator trait signature has been significantly modified in order to handle uninitialized matrices in a sound way.

  Modified

  • Orthographic3::from_matrix_unchecked is now const fn.
  • Perspective3::from_matrix_unchecked is now const fn.
  • Rotation::from_matrix_unchecked is now const fn.
  • 👯 The Scalar is now automatically implemented for most 'static + Clone types. Type that implement Clone but not Copy are now much safer to work with thanks to the refactoring of the Allocator system.

  ➕ Added

  • The conversion traits form the bytemuck crates are now implemented for the geometric types too.
  • Added operator overloading for Transform * UnitComplex, UnitComplex * Transform, Transform ×= UnitComplex, Transform ÷= UnitComplex.
  • ➕ Added Reflection::bias() to retrieve the bias of the reflection.
  • ➕ Added Reflection1..Reflection6 aliases for 1D to 6D reflections.
  • ➕ Added implementation of From and Into for converting between nalgebra types and types from glam 0.16 and glam 0.17. These can be enabled by enabling the convert-glam016, and/or convert-glam017 cargo features.

• v0.28.0 Changes

  ➕ Added

  • Implement Hash for Transform.
  • Implement Borrow and BorrowMut for contiguous slices.

  Modified

  • The OPoint<T, D> type has been added. It takes the dimension number as a type-level integer (e.g. Const<3>) instead of a const-generic. The type Point<T, const D: usize> is now an alias for OPoint. This changes doesn't affect any of the existing code using Point. However, it will allow the use OPoint in a generic context where the dimension cannot be easily expressed as a const-generic (because of the current limitation of const-generics in Rust).
  • ⚠ Several clippy warnings were fixed. This results in some method signature changes (e.g. taking self instead of &self) but this should not have any practical infulances on existing codebase.
  • The Point::new constructors are no longer const-fn. This is due to some limitations in const-fn not allowing custom trait-bounds. Use the point! macro instead to build points in const environments.
  • Dynamic::new and Unit::new_unchecked are now const-fn.
  • Methods returning Result<(), ()> now return bool instead.

  🛠 Fixed

  • 🛠 Fixed a potential unsoundess issue when converting a mutable slice to a &mut[T].

• v0.27.1 Changes

  🛠 Fixed

  • 🛠 Fixed a bug in the conversion from glam::Vec2 or glam::DVec2 to Isometry2.

• v0.27.0 Changes

  🚚 This removes the convert-glam and convert-glam-unchecked optional features. Instead, this adds the convert-glam013, convert-glam014, and convert-glam015 optional features for conversions targeting the versions 0.13, 0.14, and 0.15 of glam.

  ➕ Added

  • ➕ Add macros matrix!, dmatrix!, vector!, dvector!, point! for constructing matrices/vectors/points in a more convenient way. See #886 and #899.
  • ➕ Add CooMatrix::reserve to nalgebra-sparse.
    
  • ➕ Add basic support for serialization using rkyv. Can be enabled with the features rkyv-serialize or rkyv-serialize-no-std.

  🛠 Fixed

  • 🛠 Fixed a potential unsoundness issue after deserializing an invalid DVector using serde.
