This file declares a Pixelization subclass for the modified Q3C indexing scheme.
Mq3cPixelization provides modified Q3C indexing of points and regions.
static ConvexPolygon quad(std::uint64_t i)
quad returns the quadrilateral corresponding to the modified Q3C pixel with index i.
static constexpr int MAX_LEVEL
The maximum supported cube-face grid resolution is 2^30 by 2^30.
static int level(std::uint64_t i)
level returns the subdivision level of the given modified Q3C index.
int getLevel() const
getLevel returns the subdivision level of this pixelization.
static std::string asString(std::uint64_t i)
toString converts the given modified-Q3C index to a human readable string.
static std::vector< std::uint64_t > neighborhood(std::uint64_t i)
neighborhood returns the indexes of all pixels that share a vertex with pixel i (including i itself).
