Struct cgmath::Basis3

pub struct Basis3<S> { /* fields omitted */ }

A three-dimensional rotation matrix.

The matrix is guaranteed to be orthogonal, so some operations, specifically inversion, can be implemented more efficiently than the implementations for math::Matrix3. To ensure orthogonality is maintained, the operations have been restricted to a subset of those implemented on Matrix3.

Methods

impl<S: BaseFloat> Basis3<S>

pub fn from_quaternion(quaternion: &Quaternion<S>) -> Basis3<S>
