Now personalized customization has become a fashion and trend, and it has upgraded the brand quality and culture of enterprises.In the new economic era led by big data, enterprises will take the initiative in the new economy if they can timely obtain and meet the personalized needs of different consumers.This paper took the acquisition of users' personalized and customized requirements for ceramic products through the network as case study, in which the components of ceramic products was digitized and stored in the cloud server, realizing online free 3D composite design of ceramic products by Web3D technology. At the same time, the cloud decoration pattern library resources or online independent design of decorative patterns were used for pattern decoration on ceramic products, and the mathematical model of correlation degree between pattern resources and shape was established to help ordinary users to improve the beauty of ceramic product design works. The interactive object model provided by Fabric. js on Canvas element was employed in online interactive decorative pattern design to realize the generation and editing of decorative patterns, and image filter transformation was realized by convolution operation in pattern editing. By establishing the mapping relationship between the design pattern canvas and the ceramic 3D model, the virtual display of ceramic 3D model with strong sense of reality was generated.The research results can be used for online 3D interactive customization and display promotion of ceramic products, which can not only meet consumers' requirements for personalized customization of ceramic products, but also create a new marketing mode for the current ceramic market, so as to achieve the growth of sales.
