Struct euclid::Translation3D

source ·
#[repr(C)]
pub struct Translation3D<T, Src, Dst> { pub x: T, pub y: T, pub z: T, /* private fields */ }
Expand description

A 3d transformation from a space to another that can only express translations.

The main benefit of this type over a Vector3D is the ability to cast between source and destination spaces.

impl<T: NumCast + Copy, Src, Dst> Translation3D<T, Src, Dst>

source

pub fn cast<NewT: NumCast>(self) -> Translation3D<NewT, Src, Dst>

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

When casting from floating vector 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.

source

pub fn try_cast<NewT: NumCast>(self) -> Option<Translation3D<NewT, Src, Dst>>

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

When casting from floating vector 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.

source

source

pub fn to_usize(self) -> Translation3D<usize, Src, Dst>

Cast into an usize vector, truncating decimals if any.

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

source

pub fn to_u32(self) -> Translation3D<u32, Src, Dst>

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

source

pub fn to_i64(self) -> Translation3D<i64, Src, Dst>

Cast into an i64 vector, truncating decimals if any.
