Nowadays　computer　graphics　over　the　Internet　has　attracted　a　lot　of　attentions;　however　transmitting　3D　model　takes　a　long　time.　In　this　paper,　a　novel　framework　of　geometry　image　coding　is　proposed　which　utilized　the　image　compression　standard　to　represent　3D　model.　The　mesh　data　of　3D　model　is　first　converted　into　geometry　image　and　normal　map　image,　and　then　normal　map　image　can　be　predicted　by　geometry　image.　Hence,　only　the　geometry　image　and　residual　normal　map　image　should　be　transmitted.　Moreover,　these　images　are　compressed　using　directional　lifting　wavelet　transform.　According　to　the　experiments,　both　objective　and　subjective　performances　of　3D　model　are　enhanced,　the　photorealistic　rendering　is　improved　and　the　time　of　transmission　is　reduced.　Most　importantly,　this　proposed　framework　is　more　adapted　to　integrate　into　industry　since　it　is　based　on　improved　JPEG2000　standard.　©　2009　Springer-Verlag　Berlin　Heidelberg.
