摘要：A method for compressing 3-D geometry data which includes information describing vertices of a plurality of geometric primitives representing a surface of a three-dimensional graphical object, said method comprising: determining a first quantization threshold for a first vertex parameter value, wherein said first vertex parameter value corresponds to a first vertex of said vertices of said plurality of geometric primitives;compressing said first vertex parameter value to a number of bits specified by said first quantization threshold, thereby producing a quantized first parameter value;associating a first tag value with said quantized first parameter value, wherein said first tag value is usable to determine a length of said quantized first parameter value during decompression; andencoding said first tag value and said quantized first parameter value in a compressed data stream.
