Implementations
sourceimpl Mat2
impl Mat2
sourcepub fn from_cols(x_axis: Vec2, y_axis: Vec2) -> Mat2
pub fn from_cols(x_axis: Vec2, y_axis: Vec2) -> Mat2
Creates a 2x2 matrix from two column vectors.
sourcepub fn from_cols_array(m: &[f32; 4]) -> Mat2
pub fn from_cols_array(m: &[f32; 4]) -> Mat2
Creates a 2x2 matrix from a [f32; 4]
stored in column major order. If
your data is stored in row major you will need to transpose
the
returned matrix.
sourcepub fn to_cols_array(&self) -> [f32; 4]
pub fn to_cols_array(&self) -> [f32; 4]
Creates a [f32; 4]
storing data in column major order.
If you require data in row major order transpose
the matrix first.
sourcepub fn from_cols_array_2d(m: &[[f32; 2]; 2]) -> Mat2
pub fn from_cols_array_2d(m: &[[f32; 2]; 2]) -> Mat2
Creates a 2x2 matrix from a [[f32; 2]; 2]
stored in column major
order. If your data is in row major order you will need to transpose
the returned matrix.
sourcepub fn to_cols_array_2d(&self) -> [[f32; 2]; 2]
pub fn to_cols_array_2d(&self) -> [[f32; 2]; 2]
Creates a [[f32; 2]; 2]
storing data in column major order.
If you require data in row major order transpose
the matrix first.
sourcepub fn from_scale_angle(scale: Vec2, angle: f32) -> Mat2
pub fn from_scale_angle(scale: Vec2, angle: f32) -> Mat2
Creates a 2x2 matrix containing the given scale
and rotation of
angle
(in radians).
sourcepub fn from_angle(angle: f32) -> Mat2
pub fn from_angle(angle: f32) -> Mat2
Creates a 2x2 matrix containing a rotation of angle
(in radians).
sourcepub fn from_scale(scale: Vec2) -> Mat2
pub fn from_scale(scale: Vec2) -> Mat2
Creates a 2x2 matrix containing the given non-uniform scale
.
pub fn set_x_axis(&mut self, x: Vec2)
please use .x_axis
instead
pub fn set_y_axis(&mut self, y: Vec2)
please use .y_axis
instead
pub fn x_axis(&self) -> Vec2
please use .x_axis
instead
pub fn y_axis(&self) -> Vec2
please use .y_axis
instead
pub fn x_axis_mut(&mut self) -> &mut Vec2
please use .x_axis
instead
pub fn y_axis_mut(&mut self) -> &mut Vec2
please use .x_axis
instead
sourcepub fn determinant(&self) -> f32
pub fn determinant(&self) -> f32
Returns the determinant of self
.
sourcepub fn inverse(&self) -> Mat2
pub fn inverse(&self) -> Mat2
Returns the inverse of self
.
If the matrix is not invertible the returned matrix will be invalid.
sourcepub fn mul_scalar(&self, other: f32) -> Mat2
pub fn mul_scalar(&self, other: f32) -> Mat2
Multiplies a 2x2 matrix by a scalar.
sourcepub fn abs_diff_eq(&self, other: Mat2, max_abs_diff: f32) -> bool
pub fn abs_diff_eq(&self, other: Mat2, 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 Mat2
’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.
