Abstract: The shortcoming of traditional design process of lighting is analyzed, and a
practicable plan of collaborative design between customer and designer is presented. Crucial
technology in the collaborative design of lighting based on Web3D is particularly described which
includes how to achieve interaction, synchronization and mutual repellence in lighting design.
And it developed an online design system based on web3d technology in which the customers
play the host role while the designers play the consultant role. The system has been validated by
experiment.

Key words: product customization, synchronization scenarios show, collaborative design;
Web3D technology
