Struct Translation3D

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

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.

Fields

x: T

y: T

z: T

assert_eq!(Translation3D::new(0, 0, 1).is_identity(), false);

pub fn transform_size(self, s: Size2D<T, Src>) -> Size2D<T, Dst>

No-op, just cast the unit.

where T: NumCast + Copy,

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

where NewT: NumCast,

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.

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

where NewT: NumCast,

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.

Cast into an f32 vector.

pub fn to_f64(self) -> Translation3D<f64, Src, Dst>

Cast into an f64 vector.

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.

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