Enum gltf_json::animation::Interpolation

pub enum Interpolation {
    Linear,
    Step,
    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.

CubicSpline

Cubic spline interpolation.

The animation’s interpolation is computed using a cubic spline with specified tangents. The number of output elements must equal three times the number of input elements. For each input element, the output stores three elements, an in-tangent, a spline vertex, and an out-tangent. There must be at least two keyframes when using this interpolation
