Available kind of interpolations.

Variants

Step(T)

Hold a Key until the sampling value passes the normalized step threshold, in which case the next key is used.

Note: if you set the threshold to 0.5, the first key will be used until half the time between the two keys; the second key will be in used afterwards. If you set it to 1.0, the first key will be kept until the next key. Set it to 0. and the first key will never be used.

Linear

Linear interpolation between a key and the next one.

Cosine

Cosine interpolation between a key and the next one.

CatmullRom

Catmull-Rom interpolation, performing a cubic Hermite interpolation using four keys.

Bezier(V)

Bézier interpolation.

A control point that uses such an interpolation is associated with an extra point. The segmant connecting both is called the tangent of this point. The part of the spline defined between this control point and the next one will be interpolated across with Bézier interpolation. Two cases are possible:

• The next control point also has a Bézier interpolation mode. In this case, its tangent is used for the interpolation process. This is called cubic Bézier interpolation and it kicks ass.
• The next control point doesn’t have a Bézier interpolation mode set. In this case, the tangent used for the next control point is defined as the segment connecting that control point and the current control point’s associated point. This is called quadratic Bézer interpolation and it kicks ass too, but a bit less than cubic.
