The paper describes a method for compression of geometry data stream in distributed parallel rendering systems. First this paper uses edge collapse method with discrete curvature error metric to construct multi-resolution models, and use variable quantization of precision to compression 3-dimensional models; then models were provided to view-dependent progressive transmission method to deal with, and implement it with a distributed parallel rendering system for virtual manufacturing; While this paper use the parallelogram prediction of vertex coordinates and the angular space within one sextant of normal to compress 3-dimensional models, alleviating network bandwidth bottleneck.
