Document

Return a cell given its face (range 0..5), 61-bit Hilbert curve position within that face, and level (range 0..MAX_LEVEL).

Usage

From source file:org.geosde.cassandra.GeometryTestCase.java

/**
 * Return a random cell id at the given level or at a randomly chosen level.
 * The distribution is uniform over the space of cell ids, but only
 * approximately uniform over the surface of the sphere.

public S2CellId getRandomCellId(int level) {
    int face = random(S2CellId.NUM_FACES);
    long pos = rand.nextLong() & ((1L << (2 * S2CellId.MAX_LEVEL)) - 1);
    return S2CellId.fromFacePosLevel(face, pos, level);
