Abstract

The present invention discloses a vertex position multistage-compression method of 3-D graphics models using predictive residual vector quantization. It is an object of the present invention to provide a compression method for compressing vertex position data of a 3-D graphics model into multilevel by repeatedly performing a process by which predictive errors of vertex position are vector-quantized and then compressed, and the predictive residual signals are calculated and vector-quantized. To accomplish the object, the compression method according to the present invention, which is applied to an encoding and decoding apparatus of 3-D graphics models, includes (1) obtaining predictive errors of vertex position and then vector-quantizing/compressing them; and (2) obtaining quantization errors, repeatedly performing vector-quantization process for the obtained quantization errors and then compressing them into multistage.
