Fields
matrix2: DMat2
translation: DVec2
Implementations
impl DAffine2
[src]
impl DAffine2
[src]pub const ZERO: Self
[src]
pub const ZERO: Self
[src]The degenerate zero transform.
This transforms any finite vector and point to zero. The zero transform is non-invertible.
pub const IDENTITY: Self
[src]
pub const IDENTITY: Self
[src]The identity transform.
Multiplying a vector with this returns the same vector.
pub fn from_scale(scale: DVec2) -> Self
[src]
pub fn from_scale(scale: DVec2) -> Self
[src]Creates an affine transform that changes scale. Note that if any scale is zero the transform will be non-invertible.
pub fn from_angle(angle: f64) -> Self
[src]
pub fn from_angle(angle: f64) -> Self
[src]Creates an affine transform from the given rotation angle
.
pub fn from_translation(translation: DVec2) -> Self
[src]
pub fn from_translation(translation: DVec2) -> Self
[src]Creates an affine transformation from the given 2D translation
.
pub fn from_mat2(matrix2: DMat2) -> Self
[src]
pub fn from_mat2(matrix2: DMat2) -> Self
[src]Creates an affine transform from a 2x2 matrix (expressing scale, shear and rotation)
pub fn from_mat2_translation(matrix2: DMat2, translation: DVec2) -> Self
[src]
pub fn from_mat2_translation(matrix2: DMat2, translation: DVec2) -> Self
[src]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)
pub fn from_scale_angle_translation(
scale: DVec2,
angle: f64,
translation: DVec2
) -> Self
[src]
pub fn from_scale_angle_translation(
scale: DVec2,
angle: f64,
translation: DVec2
) -> Self
[src]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)
pub fn from_angle_translation(angle: f64, translation: DVec2) -> Self
[src]
pub fn from_angle_translation(angle: f64, translation: DVec2) -> Self
[src]Creates an affine transform from the given 2D rotation angle
(in radians) and
translation
.
Equivalent to Affine2::from_translation(translation) * Affine2::from_angle(angle)
pub fn transform_point2(&self, other: DVec2) -> DVec2
[src]
pub fn transform_point2(&self, other: DVec2) -> DVec2
[src]Transforms the given 2D point, applying shear, scale, rotation and translation.
pub fn transform_vector2(&self, other: DVec2) -> DVec2
[src]
pub fn transform_vector2(&self, other: DVec2) -> DVec2
[src]Transforms the given 2D vector, applying shear, scale and rotation (but NOT translation).
To also apply translation, use Self::transform_point2
instead.
pub fn is_finite(&self) -> bool
[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 abs_diff_eq(&self, other: Self, max_abs_diff: f64) -> bool
[src]
pub fn abs_diff_eq(&self, other: Self, max_abs_diff: f64) -> 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 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.
