The invention discloses a stream transmission method for a three-dimension model facing a mobile terminal. The method comprises the steps of conducting global parameterization on the three-dimension model by utilization of the MAPS algorithm, partitioning the three-dimension model into geometrical information, parameter information and connectedness information, and building a self-adaptive approximate semi-canonical model; then conducting inverse improved loop small wave conversion on the semi-canonical model to obtain a base grid and side-play mount, conducting zero-tree coding on the side-play mount to further conduct entropy coding, and based on a mobile terminal platform, compressing the base grid through single resolution based on the edge breaker algorithm; finally decoding through the inverse process simplified by the grid, and drawing an original model. The stream transmission method is moderate in calculated amount and high in decompression speed, is mainly applied to a PC on a mobile network to transmit complex three-dimension model to the mobile terminal, and improves the topology compression ratio and the geometry compression ratio to a certain degree.
