Geometry Proximity Node

The Geometry Proximity node computes the closest location on the target geometry.

Tips

The Map Range Node is often helpful to use with the distance output of this node to create a falloff with a maximum distance.

Inputs

Geometry

Standard geometry input.

Group ID

Splits the elements of the input geometry into groups which can be sampled individually.

Sample Position

The given position to calculate the closest location on the target.

Sample Group ID

Determines in which group the closest nearest element is detected.

Properties

Target Element

Faces:

Calculate the closest point anywhere on the faces of the target’s mesh geometry.

Edges:

Calculate the closest point anywhere on the edges of the target’s mesh geometry.

Points:

Calculate the closest point or vertex on the target geometry. This mode is usually the fastest. This mode works for both point cloud and mesh geometry, the other modes only work for meshes.

Outputs

Position

Closest location on the surface of the target mesh, or the closest point in the target point cloud in Points mode.

Distance

Distance (as floating-point value) from the source position to the closest location in the target.

Is Valid

Whether the sampling was successful. It can fail when the sampled group is empty.

Examples

The different modes of the node: faces, edges and points. In this example the Geometry Nodes modifier is added on the target plane. Note that the larger plane is subdivided and the smaller plane is not.
