An improved PM of 3D textured model for mobile device

摘要

This paper presents a new progressive mesh simplified algorithm for triangle textured meshes.We use smallest dihedral and shortest edge principle to preserve geometry boundary and RGB value difference method to keep texture boundary.Our method did better in preserving visual important area of the original mesh than some traditional methods like quadratic error metrics.The way of measuring texture distortion we use the maximum value of median line deflection angles among the adjacent area of the collapsing edge.This method was much easier to achieve and also has less computation.Preliminary experimental results show that the algorithm performs well.
