Methods

impl Mat3

pub fn zero() -> Self

pub fn identity() -> Self

pub fn new(x_axis: Vec3, y_axis: Vec3, z_axis: Vec3) -> Self

Deprecated since 0.7.2:

please use Mat3::from_cols instead

pub fn from_cols(x_axis: Vec3, y_axis: Vec3, z_axis: Vec3) -> Self

Creates a new Mat3 from three column vectors.

pub fn from_cols_array(m: &[f32; 9]) -> Self

Creates a new Mat3 from a [f32; 9] stored in column major order. If your data is stored in row major you will need to transpose the resulting Mat3.

pub fn to_cols_array(&self) -> [f32; 9]

Creates a new [f32; 9] storing data in column major order. If you require data in row major order transpose the Mat3 first.

pub fn from_cols_array_2d(m: &[[f32; 3]; 3]) -> Self

Creates a new Mat3 from a [[f32; 3]; 3] stored in column major order. If your data is in row major order you will need to transpose the resulting Mat3.

pub fn to_cols_array_2d(&self) -> [[f32; 3]; 3]

Creates a new [[f32; 3]; 3] storing data in column major order. If you require data in row major order transpose the Mat3 first.

pub fn from_scale_angle_translation(
    scale: Vec2,
    angle: f32,
    translation: Vec2
) -> Self

Creates a new Mat3 that can scale, rotate and translate a 2D vector. angle is in radians.

pub fn from_quat(rotation: Quat) -> Self

pub fn from_axis_angle(axis: Vec3, angle: f32) -> Self

Create a 3x3 rotation matrix from a normalized rotation axis and angle (in radians).

pub fn from_rotation_ypr(yaw: f32, pitch: f32, roll: f32) -> Self

Create a 3x3 rotation matrix from the given euler angles (in radians).

pub fn from_rotation_x(angle: f32) -> Self

Create a 3x3 rotation matrix from the angle (in radians) around the x axis.

pub fn from_rotation_y(angle: f32) -> Self

Create a 3x3 rotation matrix from the angle (in radians) around the y axis.

pub fn from_rotation_z(angle: f32) -> Self

Create a 3x3 rotation matrix from the angle (in radians) around the z axis.

pub fn from_scale(scale: Vec3) -> Self

pub fn set_x_axis(&mut self, x: Vec3)

pub fn set_y_axis(&mut self, y: Vec3)

pub fn set_z_axis(&mut self, z: Vec3)

pub fn x_axis(&self) -> Vec3

pub fn y_axis(&self) -> Vec3

pub fn z_axis(&self) -> Vec3

pub fn transpose(&self) -> Self

pub fn determinant(&self) -> f32

pub fn inverse(&self) -> Self

pub fn mul_vec3(&self, other: Vec3) -> Vec3

pub fn mul_mat3(&self, other: &Self) -> Self

Multiplies two 3x3 matrices.

pub fn add_mat3(&self, other: &Self) -> Self

pub fn sub_mat3(&self, other: &Self) -> Self

pub fn mul_scalar(&self, other: f32) -> Self

pub fn transform_point2(&self, other: Vec2) -> Vec2

pub fn transform_vector2(&self, other: Vec2) -> Vec2

pub fn abs_diff_eq(&self, other: Self, max_abs_diff: f32) -> bool

Returns true if the absolute difference of all elements between self and other is less than or equal to max_abs_diff.

This can be used to compare if two Mat3's contain similar elements. It works best when comparing with a known value. The max_abs_diff that should be used used depends on the values being compared against.
