}

Defines different ways of turning a Morton index into a string

Variants

AsOctantConcatenation

Concatenate the octant numbers of all octants in the Morton index to form a string. This yields strings of like 0725463, encoding octant 0 below root, 7 below 0 and so on. With this naming, a Morton index representing the root node yields an empty string

AsOctantConcatenationWithRoot

Like AsOctantConcatenation, but appends a r to the front of the string, so that a Morton index representing the root node yields the string r

AsGridCoordinates

Encodes the X, Y, and Z coordinates within the grid that the Morton index describes, together with the depth of the Morton index. This yields strings of the form 4-15-8-3 for a Morton index at level 4 that represents the grid cell (15,8,3) at this level. A Morton index representing the root node always yields the string 0-0-0-0, representing grid cell (0,0,0) at level 0. Beware: The MortonIndex64 type always stores a node of depth 21, so a default-constructed MortonIndex64 will yield 21-0-0-0 instead of 0-0-0-0!
