采样最近的表面

The Sample Nearest Surface node finds values at the closest points on the surface of a source mesh geometry. Non-face attributes are interpolated across the surface.

This node is similar to the 几何接近, but it gives the value of any attribute at the closest surface point, not just its position.

Warning

Because the node samples the surface of a mesh rather than its edges or vertices, values from loose points and edges are ignored.

输入

网格

要检索属性的几何图形。

数值

用于与传输方法一起使用的 源 几何体上的求值字段。

群组 ID

Is evaluated on the face domain and splits the input mesh into multiple parts, each with its own id.

采样位置

The position to start from when finding the closest location on the target mesh. By default, this is the same as if the 位置节点 was connected.

采样群组 ID

Determines in which group the closest nearest surface is detected.

输出

数值

The data retrieved and interpolated from the Source geometry, mapped based on the node’s settings and inputs.
