virtual std::unique_ptr< Region > pixel(uint64_t i) const =0
virtual RangeSet universe() const =0
universe returns the set of all pixel indexes for this pixelization.
virtual std::string toString(uint64_t i) const =0
toString converts the given pixel index to a human-readable string.

Definition: Pixelization.h:143
virtual uint64_t index(UnitVector3d const &v) const =0
index computes the index of the pixel for v.
