Function vec3::cross

pub fn cross<'out, T>(
    out: &'out mut [T; 3], 
    a: &[T; 3], 
    b: &[T; 3]
) -> &'out mut [T; 3] where
    T: Sub<T, Output = T>,
    &'a T: Mul<&'b T, Output = T>, 

Example

let mut v = vec3::new_zero();
vec3::cross(&mut v, &[1, 0, 0], &[0, 1, 0]);
assert_eq!(v, [0, 0, 1]);
