Type Definition nalgebra::base::Matrix3

pub type Matrix3<T> = Matrix<T, U3, U3, ArrayStorage<T, 3, 3>>;

A stack-allocated, column-major, 3x3 square matrix.

Because this is an alias, not all its methods are listed here. See the Matrix type too.

Implementations

impl<T: RealField> Matrix3<T>

2D transformations as a Matrix3

pub fn new_rotation(angle: T) -> Self

Builds a 2 dimensional homogeneous rotation matrix from an angle in radian.

pub fn new_nonuniform_scaling_wrt_point(
    scaling: &Vector2<T>,
    pt: &Point2<T>
) -> Self

Creates a new homogeneous matrix that applies a scaling factor for each dimension with respect to point.

Can be used to implement zoom_to functionality.
