Enum smallpt::axis::Axis

pub enum Axis {
    X,
    Y,
    Z,
}

An Axis in a three-dimensional coordinate system. Used to access Vector3/Point3 structs via index.

Examples

use bvh::axis::Axis;

let mut position = [1.0, 0.5, 42.0];
position[Axis::Y] *= 4.0;

assert_eq!(position[Axis::Y], 2.0);

nalgebra structures are also indexable using Axis. For reference see [the documentation] (http://nalgebra.org/doc/nalgebra/struct.Vector3.html#method.index).

extern crate bvh;
extern crate nalgebra;

use bvh::axis::Axis;
use nalgebra::Point3;

let mut position: Point3<f32> = Point3::new(1.0, 2.0, 3.0);
position[Axis::X] = 1000.0;

assert_eq!(position[Axis::X], 1000.0);

Variants

X

Index of the X axis.

Y

Index of the Y axis.

Z

Index of the Z axis.
