This file defines an interface for pixelizations of the sphere.
This file defines an interface for spherical regions.
This file declares a class for representing unit vectors in ℝ³.
virtual std::uint64_t index(UnitVector3d const &v) const =0
index computes the index of the pixel for v.
virtual RangeSet universe() const =0
universe returns the set of all pixel indexes for this pixelization.
RangeSet interior(Region const &r, size_t maxRanges=0) const
interior returns the indexes of the pixels within the spherical region r.
virtual std::unique_ptr< Region > pixel(std::uint64_t i) const =0
pixel returns the spherical region corresponding to the pixel with index i.
virtual std::string toString(std::uint64_t i) const =0
toString converts the given pixel index to a human-readable string.
RangeSet envelope(Region const &r, size_t maxRanges=0) const
envelope returns the indexes of the pixels intersecting the spherical region r.
