sourcepub fn round(self) -> Selfwhere
T: Round,
pub fn round(self) -> Selfwhere T: Round,

pub fn lerp(self, other: Self, t: T) -> Selfwhere T: One + Sub<Output = T> + Mul<Output = T> + Add<Output = T>,
Linearly interpolate between this point and another point.
Example
use euclid::point3;
use euclid::default::Point3D;
let from: Point3D<_> = point3(0.0, 10.0, -1.0);
let to: Point3D<_> = point3(8.0, -4.0, 0.0);

sourcepub fn cast<NewT: NumCast>(self) -> Point3D<NewT, U>
pub fn cast<NewT: NumCast>(self) -> Point3D<NewT, U>
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.
sourcepub fn try_cast<NewT: NumCast>(self) -> Option<Point3D<NewT, U>>
pub fn try_cast<NewT: NumCast>(self) -> Option<Point3D<NewT, U>>
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.
sourcepub fn to_usize(self) -> Point3D<usize, U>
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.
sourcepub fn to_u32(self) -> Point3D<u32, U>
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.

sourcepub fn rem_euclid(&self, other: &Size3D<T, U>) -> Self
pub fn rem_euclid(&self, other: &Size3D<T, U>) -> Self
Calculates the least nonnegative remainder of self (mod other)
.
Example
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);
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>) -> Self
Calculates Euclidean division, the matching method for rem_euclid
.

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);
assert_eq!(p.div_euclid(&s), point3(1.0, 2.0, 0.0));
assert_eq!((-p).div_euclid(&s), point3(-2.0, -1.0, 0.0));
assert_eq!(p.div_euclid(&-s), point3(-1.0, -2.0, 0.0));
