Abstract:
Few er spec ia l po ints are used to sim ulate the true 3D en tity surface m ode ,l by u in terpolation denses, w hich has a lw ay s been the hot issue bo th a t hom e and abroad. The Curst a lgor ithm is a surface reconstruction a lgorithm on the bas is o fVorono imap in calculation geome try. It is s imp le and the reconstructed result is ve ry fine. H oweve r, it is a tim e-consum ing wo rk, and thus is lim ited in its application The paper presents a su rface reconstruction algor ithm for triang le meshes interpo lation by using the princ iple o f vertex curva tures, and acco rding to the spac ia l data, calcu lates the w eigh t o fm esh and each triang le. s centro id and rectifies it by using a ser ies o f pr inciples, and las-t ly, the user can m ake a percent to reconstruct the surface of entity. The paper also g iv es an examp le o f densed surfacem ode l to illustrate e fficiency of the m ethod based on v tk.
