nearpoints

Lists the point numbers nearest to a position, closest first, within a search radius.

group: geopointproximity

Available in every context

Usage

int[] nearpoints(<geometry>, vector pt, float maxdist)

int[] nearpoints(<geometry>, vector pt, float maxdist, int maxpts)

int[] nearpoints(<geometry>, string ptgroup, vector pt, float maxdist)

int[] nearpoints(<geometry>, string ptgroup, vector pt, float maxdist, int maxpts)

Examples

// Point Wrangle, run over Points
int pts[] = nearpoints(0, @P, chf("radius"), chi("maxpts"));
foreach (int pt; pts) {
    if (pt <= @ptnum) continue; // one line per pair
    addprim(0, "polyline", @ptnum, pt);
}

Use cases

• Plexus and web effects Build lines between nearby points.
• Neighbour lookups When you need the point numbers themselves rather than a filtered average.
