Struct nannou::glam::f64::DAffine2 [−][src]
Expand description
A 2D affine transform, which can represent translation, rotation, scaling and shear.
Fields
matrix2: DMat2
translation: DVec2
Implementations
The degenerate zero transform.
This transforms any finite vector and point to zero. The zero transform is non-invertible.
The identity transform.
Multiplying a vector with this returns the same vector.
Creates an affine transform from three column vectors.
Creates an affine transform from a [S; 6]
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; 6]
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; 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.
Creates a [[S; 2]; 3]
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 6 values in slice
.
Panics
Panics if slice
is less than 6 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 angle
.
Creates an affine transformation from the given 2D translation
.
Creates an affine transform from a 2x2 matrix (expressing scale, shear and rotation)
Creates an affine transform from a 2x2 matrix (expressing scale, shear and rotation) and a translation vector.
Equivalent to Affine2::from_translation(translation) * Affine2::from_mat2(mat2)
Creates an affine transform from the given 2D scale
, rotation angle
(in
radians) and translation
.
Equivalent to Affine2::from_translation(translation) * Affine2::from_angle(angle) * Affine2::from_scale(scale)
Creates an affine transform from the given 2D rotation angle
(in radians) and
translation
.
Equivalent to Affine2::from_translation(translation) * Affine2::from_angle(angle)
Transforms the given 2D point, applying shear, scale, rotation and translation.
Transforms the given 2D vector, applying shear, scale and rotation (but NOT translation).
To also apply translation, use Self::transform_point2
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 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.
