Trait bspline::Interpolate [−] [src]

pub trait Interpolate {
    fn interpolate(&self, other: &Self, t: f32) -> Self;
}

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 since the interpolation provided by the trait is expected to be a simple linear interpolation.

Required Methods

fn interpolate(&self, other: &Self, t: f32) -> Self

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.
