Implementations§

§

impl<T, U> Point3D<T, U>

pub fn origin() -> Point3D<T, U>
where T: Zero,

Constructor, setting all components to zero.

pub fn zero() -> Point3D<T, U>
where T: Zero,

The same as origin().

pub const fn new(x: T, y: T, z: T) -> Point3D<T, U>

Constructor taking scalar values directly.

pub fn from_lengths( x: Length<T, U>, y: Length<T, U>, z: Length<T, U> ) -> Point3D<T, U>

Constructor taking properly Lengths instead of scalar values.

pub fn splat(v: T) -> Point3D<T, U>
where T: Clone,

Constructor setting all components to the same value.

pub fn from_untyped(p: Point3D<T, UnknownUnit>) -> Point3D<T, U>

Tag a unitless value with units.

§

impl<T, U> Point3D<T, U>
where T: Copy,

pub fn to_vector(self) -> Vector3D<T, U>

Cast this point into a vector.

Equivalent to subtracting the origin to this point.

pub fn xy(self) -> Point2D<T, U>

Returns a 2d point using this point’s x and y coordinates

Returns a 2d point using this point’s x and z coordinates

Returns a 2d point using this point’s x and z coordinates

Cast into an array with x, y and z.

Example

let point: Point3D<_, Mm> = point3(1, -8, 0);

assert_eq!(point.to_array(), [1, -8, 0]);

where T: One,

pub fn to_tuple(self) -> (T, T, T)

Cast into a tuple with x, y and z.

Example

enum Mm {}

let point: Point3D<_, Mm> = point3(1, -8, 0);

assert_eq!(point.to_tuple(), (1, -8, 0));

pub fn to_tuple_4d(self) -> (T, T, T, T)
where T: One,

pub fn to_untyped(self) -> Point3D<T, UnknownUnit>

Drop the units, preserving only the numeric value.

Example

enum Mm {}

let point: Point3D<_, Mm> = point3(1, -8, 0);

assert_eq!(point.x, point.to_untyped().x);
assert_eq!(point.y, point.to_untyped().y);
assert_eq!(point.z, point.to_untyped().z);

pub fn cast_unit<V>(self) -> Point3D<T, V>

Cast the unit, preserving the numeric value.

Example

enum Mm {}
enum Cm {}

assert_eq!(point.x, point.cast_unit::<Cm>().x);
assert_eq!(point.y, point.cast_unit::<Cm>().y);
assert_eq!(point.z, point.cast_unit::<Cm>().z);

pub fn to_2d(self) -> Point2D<T, U>

Convert into a 2d point.

pub fn round(self) -> Point3D<T, U>
where T: Round,

Rounds each component to the nearest integer value.

This behavior is preserved for negative values (unlike the basic cast).

enum Mm {}

assert_eq!(point3::<_, Mm>(-0.1, -0.8, 0.4).round(), point3::<_, Mm>(0.0, -1.0, 0.0))

pub fn ceil(self) -> Point3D<T, U>
where T: Ceil,

Rounds each component to the smallest integer equal or greater than the original value.

This behavior is preserved for negative values (unlike the basic cast).

enum Mm {}

assert_eq!(point3::<_, Mm>(-0.1, -0.8, 0.4).ceil(), point3::<_, Mm>(0.0, 0.0, 1.0))

pub fn floor(self) -> Point3D<T, U>
where T: Floor,

Rounds each component to the biggest integer equal or lower than the original value.

This behavior is preserved for negative values (unlike the basic cast).

enum Mm {}

assert_eq!(point3::<_, Mm>(-0.1, -0.8, 0.4).floor(), point3::<_, Mm>(-1.0, -1.0, 0.0))

pub fn lerp(self, other: Point3D<T, U>, t: T) -> Point3D<T, U>
where T: One + Sub<Output = T> + Mul<Output = T> + Add<Output = T>,

Linearly interpolate between this point and another point.

impl<T, U> Point3D<T, U>
where T: PartialOrd,

pub fn min(self, other: Point3D<T, U>) -> Point3D<T, U>

pub fn max(self, other: Point3D<T, U>) -> Point3D<T, U>

pub fn clamp(self, start: Point3D<T, U>, end: Point3D<T, U>) -> Point3D<T, U>
where T: Copy,

Returns the point each component of which clamped by corresponding components of start and end.

Shortcut for self.max(start).min(end).

§

impl<T, U> Point3D<T, U>
where T: NumCast + Copy,

pub fn cast<NewT>(self) -> Point3D<NewT, U>
where NewT: NumCast,

Cast from one numeric representation to another, preserving the units.

When casting from floating point to integer coordinates, the decimals are truncated as one would expect from a simple cast, but this behavior does not always make sense geometrically. Consider using round(), ceil() or floor() before casting.

pub fn try_cast<NewT>(self) -> Option<Point3D<NewT, U>>
where NewT: NumCast,

Fallible cast from one numeric representation to another, preserving the units.

When casting from floating point to integer coordinates, the decimals are truncated as one would expect from a simple cast, but this behavior does not always make sense geometrically. Consider using round(), ceil() or floor() before casting.

pub fn to_f32(self) -> Point3D<f32, U>

Cast into an f32 point.

pub fn to_f64(self) -> Point3D<f64, U>

Cast into an f64 point.

pub fn to_usize(self) -> Point3D<usize, U>

Cast into an usize point, truncating decimals if any.

When casting from floating point points, it is worth considering whether to round(), ceil() or floor() before the cast in order to obtain the desired conversion behavior.

pub fn to_u32(self) -> Point3D<u32, U>

Cast into an u32 point, truncating decimals if any.

When casting from floating point points, it is worth considering whether to round(), ceil() or floor() before the cast in order to obtain the desired conversion behavior.

pub fn to_i32(self) -> Point3D<i32, U>

Cast into an i32 point, truncating decimals if any.

When casting from floating point points, it is worth considering whether to round(), ceil() or floor() before the cast in order to obtain the desired conversion behavior.

pub fn to_i64(self) -> Point3D<i64, U>

Cast into an i64 point, truncating decimals if any.

When casting from floating point points, it is worth considering whether to round(), ceil() or floor() before the cast in order to obtain the desired conversion behavior.

let s = Size3D::new(4.0, -4.0, 12.0);
assert_eq!(p.rem_euclid(&s), point3(3.0, 1.0, 0.0));
assert_eq!((-p).rem_euclid(&s), point3(1.0, 3.0, 0.0));
assert_eq!(p.rem_euclid(&-s), point3(3.0, 1.0, 0.0));

pub fn div_euclid(&self, other: &Size3D<T, U>) -> Point3D<T, U>

use euclid::point3;
use euclid::default::{Point3D, Size3D};

let p = Point3D::new(7.0, -7.0, 0.0);
let s = Size3D::new(4.0, -4.0, 12.0);
