In　order　to　describe　mesh　bit-streams　which　can　be　adapted　to　the　heterogeneity　of　network　bandwidth　and　terminals＇　graphics　capabilities,　the　concepts　of　quality　scalability　and　resolution　scalabiliry　are　introduced.　A　triangle　mesh　compression　scheme　based　on　wavelet　transform　is　proposed　to　generate　bit-streams　with　both　scalabilities.　Each　subband　corresponds　to　a　resolution　level.　Wavelet　coefficients　of　each　subband　are　bitplane　encoded　to　enable　quality　refinement　within　this　subband.　The　experimental　results　show　the　proposed　coder　has　achieved　better　compression　performance　than　that　of　PGC　(Progressive　Geometry　Compression).
