Class PointQueryService

Adds a single point to the query structure. The point id is returned when the point is found. The id Entity does not have to be a valid entity, and can be treated as an integer id. The only disallowed id is the NONE entity, which is used internally.

Explicitly build the query structure. Normally the query structure is built the first time the query runs, but you can call this function to help with timing or debugging.

Creates a new entity that has a point query structure, and can be passed to other functions in this service.

Query for the closest point to point in ps. Closeness is based on Euclidean distance. This query only considers points inside the hull around the point, which is described by maxDist (exclusive) and minDist (inclusive).

Reference query for testing only. It yields the same results as queryClosestPoint, but takes much longer to execute. Avoid using it.

Query for the n closest points to point in ps. Closeness is based on Euclidean distance. This query only considers points inside the hull around the point, which is described by maxDist (exclusive) and minDist (inclusive). Returns a list of ids and distances of the closest points, sorted by most distant first. This is slower than single-point queries. For best results, n should not be too large.

Reference query for testing only. It yields the same results as queryNClosestPoints, but takes much longer to execute. Avoid using it.

Prepares and resets a point query structure. You can use this to clear a query structure, or optimize allocations when the number of items is known ahead of time.
