Type Definition nalgebra::base::Matrix3

type Matrix3<N> = Matrix<N, U3, U3, Owned<N, U3, U3>>;

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<N: RealField> Matrix3<N>

2D transformations as a Matrix3

pub fn new_rotation(angle: N) -> Self

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

pub fn new_nonuniform_scaling_wrt_point(
    scaling: &Vector2<N>,
    pt: &Point2<N>
) -> 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.
