Expand description
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.

sourcepub const fn as_ptr(&self) -> *const f64x2
pub const fn as_ptr(&self) -> *const f64x2
Returns a constant unsafe pointer to the underlying data in the underlying type. This function is safe because all types here are repr(C) and can be represented as their underlying type.
Safety
It is up to the caller to correctly use this pointer and its bounds.

pub fn as_mut_ptr(&mut self) -> *mut f64x2
Returns a mutable unsafe pointer to the underlying data in the underlying type. This function is safe because all types here are repr(C) and can be represented as their underlying type.
Safety
It is up to the caller to correctly use this pointer and its bounds.

sourcepub fn blend(mask: m64x2, tru: Self, fals: Self) -> Self
pub fn blend(mask: m64x2, tru: Self, fals: Self) -> Self
Blend two vectors together lanewise using mask
as a mask.
This is essentially a bitwise blend operation, such that any point where
there is a 1 bit in mask
, the output will put the bit from tru
, while
where there is a 0 bit in mask
, the output will put the bit from fals

fn lerp(&self, end: Self, t: f64x2) -> 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 Rotor
s 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 Rotor
s to be of constant angular velocity. In this
case, check out Slerp
.

fn slerp(&self, end: Self, t: f64x2) -> Self
Spherical-linear interpolation between self

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 Rotor
s, 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 Rotor
s, etc!
