| Abstract: | It is a very important subject in computer geometric moulding to achieve the net curved surface of original object through processing the data of scatter points on 3D-object surface. This article introduces the concerned knowledge and developing trends of reconstructing net curved surface. from 3D scatter points, classifies the present reconstruction algorithms into three types, analyses them comparatively and points out their appliable ranges respectively. Finally the problems which need to be further studied and settled are also presented and analysed. |
