Sample Index Node
The Sample Index node retrieves values from a source geometry at a specific index.
If the Geometry used for the input is the same as the geometry from the field context, this node is equivalent to the 索引节点的字段. Using that node is usually preferrable since avoding the geometry socket makes the whole setup easier to use in other situations and share.
A field to evaluate on the source Geometry. The values are then retrieved from specific indices for the output.
Which index to use when retrieving the data from the input Value field. Any index can be connected, resulting in a "shuffling" of the values.
The data retrieved from the source Geometry input.
