Nodo Evaluar en identificador

The Evaluate at Index node allows accessing data of other elements in the context geometry. It is similar to the Nodo Muestrear identificador. The main difference is that this node does not require a geometry input, because the geometry from the field context is used.

This node is also similar to the Nodo Evaluar en dominio node, except that the value to retrieve from the specified domain is specified by an index rather than an automatic domain interpolation.
