Enum gltf_json::animation::Interpolation

pub enum Interpolation {
    Linear = 1,

    CubicSpline = 4,
}

Specifies an interpolation algorithm.

Variants

Linear = 1

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 = 2

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 = 3

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 = 4

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.

Trait Implementations

impl Clone for Interpolation

fn clone(&self) -> Interpolation

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Interpolation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Interpolation

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Interpolation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Interpolation

fn eq(&self, other: &Interpolation) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Interpolation

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Interpolation

impl Eq for Interpolation

impl StructuralPartialEq for Interpolation
