采样编号¶

采样编号 节点在源几何体的特定编号上检索数值。
Tip
Different components can have same attribute domain (Points). This node simply uses first component that not empty for such domain, checked in the order of: Mesh, Point Cloud, Curve. The 分离组件 can be used to sample directly from a specific component.
输入¶
- 几何数据
要检索属性的几何图形。
- 数值
A field to evaluate on the source Geometry. The values are then retrieved from specific indices for the output.
- 编号
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.
属性¶
输出¶
- 数值
从输入端源 几何 检索出的数据。
示例¶

Here the node is used to copy the positions of one object to another. This recreates the behavior of the Transfer Attribute node from Blender versions before 3.4. This works best when their geometries have the same number of points and the same Topology.¶
