A system is described for generating a plurality of identifiers, each associated with one of a like plurality of subdivision surfaces of a surface element, and for generating, using an identifier for a subdivision surface, coordinates for the subdivision surface. Each identifier includes one or more position codes. Each position code indicates the position of a subdivision surface at a respective level relative to the next higher level, so that successive position codes in the identifier indicate the positions of subdivision surfaces through successive subdivision levels. To generate coordinates for a subdivision surface from the identifier associated with the subdivision surface, the system sequences through successive position codes in the identifier to determine locations of the subdivision surfaces through the successive levels.
