Each keyframe in the Curve animation track type can have a different interpolation type. These types are as follows.
| Name | Value | Description |
|---|---|---|
Hold
|
0 | The Hold interpolation type makes the current keyframe act like the Discrete Animation Track type, where it will stay at that position and when the next keyframe's time is reached, will immediately transform to the next keyframe's value. |
Linear
|
1 | The linear interpolation type will transform the value linearly from the current keyframe's value to the next keyframe's value, between the start of the current keyframe's time and the start of the next keyframe's time. |
Tangent
|
2 | Tangent is a misrepresentation of a bezier curve algorithm, which is kept in for legacy/compatibility reasons. |
