In　applications,　users　may　be　only　interested　in　parts　of　a　mesh,　and　demand　higher　reconstruction　fidelity　of　the　region　of　interest　(ROI)　than　that　of　non-ROI　at　very　low　bit　rate.　Up　to　now,　there　have　no　publications　on　ROI　coding　of　3D　meshes.　We　proposed　an　efficient　method　of　3D　mesh　ROI　coding　in　this　paper.　Two　methods　to　code　the　ROI　firstly　and　four　ROI　coding　models　are　proposed.　A　quick　scheme　for　constructing　ROI　mask　is　also　suggested.　Experimental　results　show　that　the　proposed　method　has　achieved　the　ROI　coding　of　3D　meshes　efficiently,　and　supported　the　browsing　of　3D　meshes　on　Internet　interactively　and　individually.
