Struct bevy::math::Affine3A [−][src]
Expand description
A 3D affine transform, which can represent translation, rotation, scaling and shear.
The type is composed of a 3x3 matrix containing a linear transformation (e.g. scale, rotation, shear, reflection) and a 3D vector translation.
Fields
matrix3: Mat3A
translation: Vec3A
Implementations
Transforms the given Vec3A
, applying shear, scale, rotation and translation.
Transforms the given Vec3A
, applying shear, scale and rotation (but NOT
translation).
To also apply translation, use Self::transform_point3
instead.
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 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 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.
