This file declares a Pixelization subclass for the Q3C indexing scheme.
Q3cPixelization provides Q3C indexing of points and regions.
ConvexPolygon quad(std::uint64_t i) const
quad returns the quadrilateral corresponding to the Q3C pixel with index i.
int getLevel() const
getLevel returns the subdivision level of this pixelization.
static constexpr int MAX_LEVEL
The maximum supported cube-face grid resolution is 2^30 by 2^30.
std::vector< std::uint64_t > neighborhood(std::uint64_t i) const
neighborhood returns the indexes of all pixels that share a vertex with pixel i (including i itself).
