The PositionInterpolator2DEx node interpolates among a list of SFVec2f values using a specified interpolation method. This node extends the ParallelGraphics extension node Position2Interpolator.

The type field defines the interpolation method. The possible values of this field are "CONSTANT", "LINEAR", "COSINE", "CUBIC" and "HERMITE". In the case of the Hermite interpolation, the params field specifies three interpolation parameters: Tension, Continuity and Bias.
Definitions of the other fields and events of the PositionInterpolator2DEx node are similar to the corresponding definitions for the ParallelGraphics extension node Position2Interpolator.
