Implementations§

source§

impl DAffine2

source

pub const ZERO: DAffine2 = _

The degenerate zero transform.

This transforms any finite vector and point to zero. The zero transform is non-invertible.

source

pub const IDENTITY: DAffine2 = _

The identity transform.

Multiplying a vector with this returns the same vector.

source

pub const NAN: DAffine2 = _

All NAN:s.

source

pub const fn from_cols(x_axis: DVec2, y_axis: DVec2, z_axis: DVec2) -> DAffine2

Creates an affine transform from three column vectors.

source

pub fn from_cols_array(m: &[f64; 6]) -> DAffine2

Creates an affine transform from a [f64; 6] array stored in column major order.

source

pub fn to_cols_array(&self) -> [f64; 6]

Creates a [f64; 6] array storing data in column major order.

source

pub fn from_cols_array_2d(m: &[[f64; 2]; 3]) -> DAffine2

Creates an affine transform from a [[f64; 2]; 3] 2D array stored in column major order. If your data is in row major order you will need to transpose the returned matrix.

source

pub fn to_cols_array_2d(&self) -> [[f64; 2]; 3]

Creates a [[f64; 2]; 3] 2D array storing data in column major order. If you require data in row major order transpose the matrix first.

source

pub fn from_cols_slice(slice: &[f64]) -> DAffine2

Creates an affine transform from the first 6 values in slice.

§Panics

Panics if slice is less than 6 elements long.

source

pub fn write_cols_to_slice(self, slice: &mut [f64])

Writes the columns of self to the first 6 elements in slice.

§Panics

Panics if slice is less than 6 elements long.

source

pub fn from_scale(scale: DVec2) -> DAffine2

Creates an affine transform that changes scale. Note that if any scale is zero the transform will be non-invertible.

source

pub fn from_angle(angle: f64) -> DAffine2

Creates an affine transform from the given rotation angle.

source

pub fn from_translation(translation: DVec2) -> DAffine2

Creates an affine transformation from the given 2D translation.

source

pub fn from_mat2(matrix2: DMat2) -> DAffine2

Creates an affine transform from a 2x2 matrix (expressing scale, shear and rotation)

source

pub fn from_mat2_translation(matrix2: DMat2, translation: DVec2) -> DAffine2

Creates an affine transform from a 2x2 matrix (expressing scale, shear and rotation) and a translation vector.

Equivalent to DAffine2::from_translation(translation) * DAffine2::from_mat2(mat2)

source

pub fn from_scale_angle_translation( scale: DVec2, angle: f64, translation: DVec2, ) -> DAffine2

Creates an affine transform from the given 2D scale, rotation angle (in radians) and translation.

Equivalent to DAffine2::from_translation(translation) * DAffine2::from_angle(angle) * DAffine2::from_scale(scale)

source

pub fn from_angle_translation(angle: f64, translation: DVec2) -> DAffine2

Creates an affine transform from the given 2D rotation angle (in radians) and translation.

Equivalent to DAffine2::from_translation(translation) * DAffine2::from_angle(angle)

source

pub fn from_mat3(m: DMat3) -> DAffine2

The given DMat3 must be an affine transform,

source

pub fn to_scale_angle_translation(self) -> (DVec2, f64, DVec2)

Extracts scale, angle and translation from self.

The transform is expected to be non-degenerate and without shearing, or the output will be invalid.

§Panics

Will panic if the determinant self.matrix2 is zero or if the resulting scale vector contains any zero elements when glam_assert is enabled.

source

pub fn transform_point2(&self, rhs: DVec2) -> DVec2

Transforms the given 2D point, applying shear, scale, rotation and translation.

source

pub fn transform_vector2(&self, rhs: DVec2) -> DVec2

Transforms the given 2D vector, applying shear, scale and rotation (but NOT translation).

To also apply translation, use Self::transform_point2() instead.

source

pub fn is_finite(&self) -> bool

Returns true if, and only if, all elements are finite.

If any element is either NaN, positive or negative infinity, this will return false.

source

pub fn is_nan(&self) -> bool

Returns true if any elements are NaN.

source

pub fn abs_diff_eq(&self, rhs: DAffine2, max_abs_diff: f64) -> bool

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

This can be used to compare if two 3x4 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.

source

pub fn inverse(&self) -> DAffine2

Return the inverse of this transform.

Note that if the transform is not invertible the result will be invalid.
