Enum gltf_json::animation::Interpolation

pub enum Interpolation {
    Linear,
    Step,
    CatmullRomSpline,
    CubicSpline,
}

Specifies an interpolation algorithm.

Variants

Linear

Linear interpolation.

The animated values are linearly interpolated between keyframes. When targeting a rotation, spherical linear interpolation (slerp) should be used to interpolate quaternions. The number output of elements must equal the number of input elements.

Step

Step interpolation.

The animated values remain constant to the output of the first keyframe, until the next keyframe. The number of output elements must equal the number of input elements.

CatmullRomSpline

Uniform Catmull-Rom spline interpolation.

The animation's interpolation is computed using a uniform Catmull-Rom spline. The number of output elements must equal two more than the number of input elements. The first and last output elements represent the start and end tangents of the spline. There must be at least four keyframes when using this interpolation.

CubicSpline

Cubic spline interpolation.

The animation's interpolation is computed using a uniform Catmull-Rom spline. The number of output elements must equal two more than the number of input elements. The first and last output elements represent the start and end tangents of the spline. There must be at least four keyframes when using this interpolation.
