Struct ultraviolet::vec::DVec4

#[repr(C)]
pub struct DVec4 {
    pub x: f64,
    pub y: f64,
    pub z: f64,
    pub w: f64,
}

A set of four coordinates which may be interpreted as a point or vector in 4d space, or as a homogeneous 3d vector or point.

Generally this distinction between a point and vector is more of a pain than it is worth to distinguish on a type level, however when converting to and from homogeneous coordinates it is quite important.

Fields

x: f64

y: f64

z: f64

w: f64

impl Lerp<f64> for DVec4

fn lerp(&self, end: Self, t: f64) -> Self

Linearly interpolate between self and end by t between 0.0 and 1.0. i.e. (1.0 - t) * self + (t) * end.

For interpolating Rotors with linear interpolation, you almost certainly want to normalize the returned Rotor. For example,

let interpolated_rotor = rotor1.lerp(rotor2, 0.5).normalized();

For most cases (especially where performance is the primary concern, like in animation interpolation for games, this ‘normalized lerp’ or ‘nlerp’ is probably what you want to use. However, there are situations in which you really want the interpolation between two Rotors to be of constant angular velocity. In this case, check out Slerp.

fn eq(&self, other: &DVec4) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn serialize<T>(&self, serializer: T) -> Result<T::Ok, T::Error>where T: Serializer,

Serialize this value into the given Serde serializer.

impl Slerp<f64> for DVec4

fn slerp(&self, end: Self, t: f64) -> Self

Spherical-linear interpolation between self and end based on t from 0.0 to 1.0.

self and end should both be normalized or something bad will happen!

The implementation for SIMD types also requires that the two things being interpolated between are not exactly aligned, or else the result is undefined.

Basically, interpolation that maintains a constant angular velocity from one orientation on a unit hypersphere to another. This is sorta the “high quality” interpolation for Rotors, and it can also be used to interpolate other things, one example being interpolation of 3d normal vectors.

Note that you should often normalize the result returned by this operation, when working with Rotors, etc!
