Notice of RetractionAn improved progressive mesh model for mobile device

This paper presents a new progressive mesh simplified algorithm for triangle meshes. We use smallest dihedral and shortest edge as principles for choosing collapsing edges to create progressive mesh. Our method did better in reducing the geometry deformation than some traditional methods like quadratic error measure of volume or distance. The way of batching collapsing operations we use locking one-ring adjacent method to achieve progressive encode. This method was much easier to achieve and also made the data size of each batch much smaller. At last we compress the base mesh base on Edgebreaker algorithm which decompresses the mesh very fast and the base mesh has no geometry distortion. Preliminary experimental results show that the algorithm performs well.
