Struct Rotation 

pub struct Rotation { /* private fields */ }

A random orthogonal transform, rebuilt from its seed rather than stored.

Implementations

impl Rotation

pub fn new(dim: usize, seed: u64) -> Rotation

The rotation a collection of dim dimensional vectors uses, from the seed in its catalogue entry.

Panics

If dim is zero. A collection of vectors with no coordinates is a mistake made somewhere further up rather than a case to handle.

pub fn dim(&self) -> usize

How many coordinates a vector this rotates has.

pub fn seed(&self) -> u64

The seed this was built from, which is what a catalogue stores.

pub fn apply(&self, v: &mut [f32])

Rotate a vector where it lies.

Panics

If v is not Rotation::dim long.
