Struct euclid::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 a source and a destination spaces.

Fields

x: T

y: T

z: T
