Abstract
An adaptive hierarchical transmission mechanism of 3D mesh models for mobile terminals based on WebAR technology is introduced. By proposing a vertex merging algorithm based on vertex megring degree, the original model is decomposed into multiple groups of data consist of a simplified model and a layer file for reconstruction according to the specific compression ratio. The experiments show that the initialization time of the AR scene using the simplified model as the base model is effectively reduced and the simplified model can be reconstructed to the original model losslessly with the layer file. The proposed mechanism can be used for adaptive transmission, lossless reconstruction and real-time rendering on mobile terminals.
