The ColorInterpolatorEx node interpolates among a list of MFColor values using a specified interpolation method. This node extends the standard ColorInterpolator VRML node .

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 ColorInterpolatorEx node are similar to the corresponding definitions for the ColorInterpolator VRML node.
