Evaluate at Index Node

The Evaluate at Index node allows accessing data of other elements in the context geometry. It is similar to the Sample Index Node. 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 Evaluate on Domain Node node, except that the value to retrieve from the specified domain is specified by an index rather than an automatic domain interpolation.
