Struct glam::f32::Mat2 [−][src]
A 2x2 column major matrix.
Implementations
impl Mat2
[src]
pub const ZERO: Self
[src]
A 2x2 matrix with all elements set to 0.0
.
pub const IDENTITY: Self
[src]
A 2x2 identity matrix, where all diagonal elements are 1
, and all off-diagonal elements are 0
.
pub const fn zero() -> Self
[src]
use Mat2::ZERO instead
Creates a 2x2 matrix with all elements set to 0.0
.
pub const fn identity() -> Self
[src]
use Mat2::IDENTITY instead
Creates a 2x2 identity matrix.
pub fn from_cols(x_axis: Vec2, y_axis: Vec2) -> Self
[src]
Creates a 2x2 matrix from two column vectors.
pub fn from_cols_array(m: &[f32; 4]) -> Self
[src]
Creates a 2x2 matrix from a [S; 4]
array stored in column major order.
If your data is stored in row major you will need to transpose
the returned
matrix.
pub fn to_cols_array(&self) -> [f32; 4]
[src]
Creates a [S; 4]
array storing data in column major order.
If you require data in row major order transpose
the matrix first.
pub fn from_cols_array_2d(m: &[[f32; 2]; 2]) -> Self
[src]
Creates a 2x2 matrix from a [[S; 2]; 2]
2D array stored in column major order.
If your data is in row major order you will need to transpose
the returned
matrix.
pub fn to_cols_array_2d(&self) -> [[f32; 2]; 2]
[src]
Creates a [[S; 2]; 2]
2D array storing data in column major order.
If you require data in row major order transpose
the matrix first.
pub fn from_diagonal(diagonal: Vec2) -> Self
[src]
Creates a 2x2 matrix with its diagonal set to diagonal
and all other entries set to 0.
pub fn from_scale_angle(scale: Vec2, angle: f32) -> Self
[src]
Creates a 2x2 matrix containing the combining non-uniform scale
and rotation of
angle
(in radians).
pub fn from_angle(angle: f32) -> Self
[src]
Creates a 2x2 matrix containing a rotation of angle
(in radians).
pub fn from_scale(scale: Vec2) -> Self
[src]
Use from_diagonal() instead
pub fn col(&self, index: usize) -> Vec2
[src]
pub fn row(&self, index: usize) -> Vec2
[src]
pub fn is_finite(&self) -> bool
[src]
Returns true
if, and only if, all elements are finite.
If any element is either NaN
, positive or negative infinity, this will return false
.
pub fn is_nan(&self) -> bool
[src]
Returns true
if any elements are NaN
.
pub fn transpose(&self) -> Self
[src]
Returns the transpose of self
.
pub fn determinant(&self) -> f32
[src]
Returns the determinant of self
.
pub fn inverse(&self) -> Self
[src]
Returns the inverse of self
.
If the matrix is not invertible the returned matrix will be invalid.
pub fn mul_vec2(&self, other: Vec2) -> Vec2
[src]
Transforms a 2D vector.
pub fn mul_mat2(&self, other: &Self) -> Self
[src]
Multiplies two 2x2 matrices.
pub fn add_mat2(&self, other: &Self) -> Self
[src]
Adds two 2x2 matrices.
pub fn sub_mat2(&self, other: &Self) -> Self
[src]
Subtracts two 2x2 matrices.
pub fn mul_scalar(&self, other: f32) -> Self
[src]
Multiplies a 2x2 matrix by a scalar.
pub fn abs_diff_eq(&self, other: &Self, max_abs_diff: f32) -> bool
[src]
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 matrices 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.
For more see comparing floating point numbers.
