#[repr(transparent)]pub struct Euler { /* private fields */ }
Expand description
Describe a rotation using Euler angles.
The contents of the Euler
structure are private
and should never be accessed directly.
Implementations§
source§impl Euler
impl Euler
sourcepub fn order(&self) -> EulerOrder
pub fn order(&self) -> EulerOrder
Retrieves the order used to apply the rotations described in the
Euler
structure, when converting to and from other
structures, like Quaternion
and Matrix
.
This function does not return the EulerOrder::Default
enumeration value; it will return the effective order of rotation
instead.
Returns
the order used to apply the rotations
sourcepub fn reorder(&self, order: EulerOrder) -> Euler
pub fn reorder(&self, order: EulerOrder) -> Euler
sourcepub fn to_matrix(&self) -> Matrix
pub fn to_matrix(&self) -> Matrix
Converts a Euler
into a transformation matrix expressing
the extrinsic composition of rotations described by the Euler angles.
The rotations are applied over the reference frame axes in the order
associated with the Euler
; for instance, if the order
used to initialize self
is EulerOrder::Xyz
:
- the first rotation moves the body around the X axis with an angle φ
- the second rotation moves the body around the Y axis with an angle of ϑ
- the third rotation moves the body around the Z axis with an angle of ψ
The rotation sign convention is right-handed, to preserve compatibility between Euler-based, quaternion-based, and angle-axis-based rotations.
Returns
res
return location for a Matrix

sourcepub fn from_quaternion(q: Option<&Quaternion>, order: EulerOrder) -> Self
pub fn from_quaternion(q: Option<&Quaternion>, order: EulerOrder) -> Self
Initializes a Euler
using the given normalized quaternion.
If the Quaternion
q
is None
, the Euler
will
be initialized with all angles set to 0.
q
a normalized Quaternion
order
the order used to apply the rotations
