Function mat32::look_at

pub fn look_at<'out, T>(
    out: &'out mut [T; 6], 
    eye: &[T; 2], 
    target: &[T; 2]
) -> &'out mut [T; 6] where
    T: Float + FromPrimitive + Add<T, Output = T>,
    &'a T: Mul<&'b T, Output = T> + Sub<&'b T, Output = T> + Neg<Output = T>, 

Example

let mut m = mat32::new_identity::<f32>();
mat32::look_at(&mut m, &[0f32, 0f32], &[0f32, 1f32]);
assert_eq!(m, [1f32, 0f32, 0f32, 1f32, 0f32, 0f32]);
