Creates an affine transform from four column vectors.

Creates an affine transform from a [S; 12] array stored in column major order. If your data is stored in row major you will need to transpose the returned matrix.

Creates a [S; 12] array storing data in column major order. If you require data in row major order transpose the matrix first.

Creates an affine transform from a [[S; 3]; 4] 2D array stored in column major order. If your data is in row major order you will need to transpose the returned matrix.

Creates a [[S; 3]; 4] 2D array storing data in column major order. If you require data in row major order transpose the matrix first.

Creates an affine transform from the first 12 values in slice.

Panics

Panics if slice is less than 12 elements long.

Writes the columns of self to the first 12 elements in slice.

Panics

Panics if slice is less than 12 elements long.

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

Creates an affine transform from the given rotation quaternion.

Creates an affine transform containing a 3D rotation around a normalized rotation axis of angle (in radians).

Creates an affine transform containing a 3D rotation around the x axis of angle (in radians).

Creates an affine transform containing a 3D rotation around the y axis of angle (in radians).

Creates an affine transform containing a 3D rotation around the z axis of angle (in radians).

Creates an affine transformation from the given 3D translation.

Creates an affine transform from a 3x3 matrix (expressing scale, shear and rotation)

Creates an affine transform from a 3x3 matrix (expressing scale, shear and rotation) and a translation vector.

Equivalent to Affine3::from_translation(translation) * Affine3::from_mat3(mat3)

Creates an affine transform from the given 3D scale, rotation and translation.

Equivalent to Affine3::from_translation(translation) * Affine3::from_quat(rotation) * Affine3::from_scale(scale)

Creates an affine transform from the given 3D rotation and translation.

Equivalent to Affine3::from_translation(translation) * Affine3::from_quat(rotation)

The given Mat4 must be an affine transform, i.e. contain no perspective transform.

Extracts scale, rotation 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.matrix3 is zero or if the resulting scale vector contains any zero elements when glam_assert is enabled.

Creates a left-handed view transform using a camera position, an up direction, and a focal point.

For a view coordinate system with +X=right, +Y=up and +Z=forward.

Panics

Will panic if up is not normalized when glam_assert is enabled.

Creates a right-handed view transform using a camera position, an up direction, and a focal point.

For a view coordinate system with +X=right, +Y=up and +Z=back.

Panics

Will panic if up is not normalized when glam_assert is enabled.

Transforms the given 3D points, applying shear, scale, rotation and translation.

Transforms the given 3D vector, applying shear, scale and rotation (but NOT translation).

To also apply translation, use Self::transform_point3 instead.

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

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

Returns true if any elements are NaN.

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 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.

Return the inverse of this transform.

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