Trait ultraviolet::interp::Lerp
source · [−]pub trait Lerp<T> {
fn lerp(&self, end: Self, t: T) -> Self;
}
Expand description
Pure linear interpolation, 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
.
