| Abstract: | To solve the problem of repairing the the cavity areas in the triangular mesh model,the essay brings up a method to solve it that is firstly measuring the cavity areas again by using the variance and average degree of curve as the influencing factors and then using direct triangulation to handle the cavity area data. |
