Struct LookAt

pub struct LookAt(pub Box<[f32; 9]>);

Contains a position and orientation transformation suitable for aiming a camera.

Tuple Fields

0: Box<[f32; 9]>

A list of 9 floating-point values. These values are organized into three vectors as follows:

1. Eye position is given as Px, Py, Pz.
2. Interest point is given as Ix, Iy, Iz.
3. Up-axis direction is given as UPx, UPy, UPz.

Implementations

impl LookAt

pub fn new(eye: [f32; 3], target: [f32; 3], up: [f32; 3]) -> Self

Construct a look-at transform from the given eye position, target position, and up direction.

pub fn eye(&self) -> &[f32; 3]

The eye position for this look-at orientation.

pub fn target(&self) -> &[f32; 3]

The target position (interest point) for this look-at orientation.

pub fn up(&self) -> &[f32; 3]

The up direction for this look-at orientation.
