The invention discloses a three-dimensional model data transmission method, a server and a user terminal. The three-dimensional model data transmission method comprises the following steps: receiving a three-dimensional model data request message from a first user terminal, wherein the request message carries the identification information of the first user terminal and the access authority of the first user terminal; according to the access authority, determining at least one piece of target segmented data of the three-dimensional model data which can be accessed by the first user terminal; obtaining a segmentation key corresponding to the at least one piece of target segmentation data; generating authorization information based on the segment key and the identification information of the first user terminal; and sending the authorization information and the encrypted target segment data to the first user terminal. Based on the above mode, the first user terminal can only obtain part of the three-dimensional model data corresponding to the access permission thereof, so that the three-dimensional model data is prevented from being leaked to persons without permission, and the security of the three-dimensional model data is improved.
Description
technical field [0001] The invention relates to the communication field, in particular to a three-dimensional model data transmission method, server and user terminal. Background technique [0002] At present, with the development of the industrial Internet and the promotion of Model Based Definition (MBD) applications, more and more enterprises will use 3D data as knowledge in collaboration, promotion, training, service, and maintenance inside and outside the enterprise. carrier. However, 3D model data, especially the geometry, bill of materials (Bill of Material, BOM), model parameters, product manufacturing information (Product and Manufacturing Information, PMI) and other data in the 3D model data describe the precise information of the model and are the core of the enterprise. intellectual property. Enterprises worry about the loss of intellectual property rights in the process of collaboration, so there is an urgent need for a method that can not only meet the deepen...
