Field at Index Node

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

Inputs – Уводи

Index – Індекс

The index of the element in the selected domain to retrieve data from, i.e. «the fourth face», or «the first control point».

Value – Значення

The field to retrieve data from.

Properties – Властивості

Домен – Domain

The attribute domain used for for evaluation of the Value input. This is useful because it can be a different domain than the domain from the field context, i.e. to choose a vertex for each face.

Вивід – Output

Value – Значення

The value of the input field at the given index.
