Evaluate on Domain Node

The Evaluate on Domain allows evaluating a field for a different attribute domain than the domain from the field context. For example, the face index could be used instead of the face corner index, when setting the values of a UV Map

Note

这个节点没有必要从其他属性域中检索数据；那是自动完成的。它的作用来自于可以控制*何时发生域插值的事实。通常情况下，输入节点在创建其输出时就将其数据插值到当前上下文的域。

Tip

It may be preferable to use this node over the 捕获属性节点, since it allows using a specific attribute domain without requiring a geometry socket input, which allows creating more reusable node groups.

The method of retrieving data from another domain is somewhat similar to the Evaluate at Index Node.
