Trait bspline::Interpolate

source · [−]
pub trait Interpolate<F> {
    fn interpolate(&self, other: &Self, t: F) -> Self;
}
Expand description

The interpolate trait is used to linearly interpolate between two types (or in the case of Quaternions, spherically linearly interpolate). The B-spline curve uses this trait to compute points on the curve for the given parameter value.

A default implementation of this trait is provided for all T that are `Mul<f32, Output = T>

  • Add<Output = T> + Copy` as these are the only operations needed to linearly interpolate the values. Any type implementing this trait should perform whatever the appropriate linear interpolaton is for the type.

Required methods

Linearly interpolate between self and other using t, for example with floats:

self * (1.0 - t) + other * t

If the result returned is not a correct linear interpolation of the values the curve produced using the value may not be correct.
