Abstract
With the development and progress of science and technology, 3D model has been applied in many fields. The size and complexity of 3D model are huge, its transmission will be affected by the limited bandwidth. Therefore, it is necessary to compress the 3D model with the progressive compression technique and then display the model during the transmission process. The existing progressive compression algorithm rarely considers the attribute information, however, the attribute information often occupies much storage space. Therefore, we takes the triangular mesh model as the research object and proposes a progressive compression algorithm using the color attribute and material attribute. The 3D mesh model is simplified with geometric coding and attribute coding during the compression. Experimental results show that the algorithm can obtain a good model compression ratio and improve the processing speed of the model.
