Class va_PersistBlend_va


public class va_PersistBlend_va
extends NodeVec2Array

Remembers Vec2s for a given period of time. If a new vector arrives, close in value to one of the existing Vec2s, they are merged according to a "blending".

For detailed information on how to configure behaviors, see the Clay page.

p - double, the persistence in seconds.
mr - double, how close things must be to be considered the same.
alpha - double, how much to weight old objects (must be 0=>alpha<=1).
im1 - NodeVec2Array, the node that generates a list of items to filter.
