【Abstract】 By contrasting the characteristics of CAD model and triangular mesh model, the paper proposes a new system of distributed collaborative design based on triangular mesh model according to the network condition and the requirements of distributed concurrent collaborative design for real-time manipulation. Then, it considers the key technology of the transmission. On the base of triangular mesh model, it realizes remote real-time and dynamic viewing of 3D product models driven by client in client/server architecture through progressive transmission, selective refinement and feature mapping. Also, it can consult and alter the feature parameters of products on-line. The system can operate regardless of design platform type.更多还原
