Trait Rotation

    // Required methods

Expand description

Subgroups of the n-dimensional rotation group SO(n).

Required Methods§

Source

fn powf(&self, n: E::RealField) -> Option<Self>

Raises this rotation to a power. If this is a simple rotation, the result must be equivalent to multiplying the rotation angle by n.

Source

fn rotation_between(a: &E::Coordinates, b: &E::Coordinates) -> Option<Self>

Computes a simple rotation that makes the angle between a and b equal to zero, i.e., b.angle(a * delta_rotation(a, b)) = 0. If a and b are collinear, the computed rotation may not be unique. Returns None if no such simple rotation exists in the subgroup represented by Self.

Source

fn scaled_rotation_between( a: &E::Coordinates, b: &E::Coordinates, s: E::RealField, ) -> Option<Self>

Computes the rotation between a and b and raises it to the power n.

This is equivalent to calling self.rotation_between(a, b) followed by .powf(n) but will usually be much more efficient.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
