The paper describes a framework for time-critical rendering of graphics scenes composed of a large number of objects having complex geometric descriptions. An algorithm for mesh simplification both view-independent and view-dependent for original complex model was presented in this paper, First this paper uses edge collapse method with discrete curvature error metric to construct multi-resolution models, then simplified models were provided to view-dependent progressive transmission method to deal with, and implement it with a immediate-mode/retained-mode hybrid distributed parallel rendering system for virtual manufacturing; While this paper use the algorithm called geometry indexing that avoids the redundant geometry transmission by indexing geometry data, alleviating network bandwidth bottleneck.
