Struct ultraviolet::bivec::Bivec2x8
source · [−]#[repr(C)]pub struct Bivec2x8 {
pub xy: f32x8,
}
Expand description
A bivector in 2d space.
Since in 2d there is only one plane in the whole of 2d space, a 2d bivector has only one component.
Please see the module level documentation for more information on bivectors generally!

sourcepub const fn as_ptr(&self) -> *const f32x8
pub const fn as_ptr(&self) -> *const f32x8
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.
sourcepub fn as_mut_ptr(&mut self) -> *mut f32x8
pub fn as_mut_ptr(&mut self) -> *mut f32x8
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.

sourceimpl Lerp<f32x8> for Bivec2x8
impl Lerp<f32x8> for Bivec2x8
sourcefn lerp(&self, end: Self, t: f32x8) -> Self
fn lerp(&self, end: Self, t: f32x8) -> 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
.

impl Slerp<f32x8> for Bivec2x8
sourcefn slerp(&self, end: Self, t: f32x8) -> Self
fn slerp(&self, end: Self, t: f32x8) -> 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 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!
