Outputs one random location on a geometry for each element in the set. Locations are "glued" to the surface of a geometry so that they stay in the same relative position even as the geometry transforms and deforms, unless you recompute and reset the locations' values at different frames.
This node is similar to the Generate Sample Set node, which generates a set of random locations based on its rate value and typically connects to an Add Point node. However, this node generates exactly one location for each set element. For example, if we're storing the location generated on each point of a point cloud, the number of locations generated will be the number of points in the point cloud.
In addition, you can also narrow from where the locations on polygon mesh geometries will be emitted by using the Filter attribute.
