Embodiment Construction

[0025] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0026] please see figure 1 , a kind of CRDT-based real-time collaborative editing method of feature CAD model provided by the present invention is characterized in that: each site is allocated and managed in real time a feature dependency graph CoFDG, a hash table, a double linked list and an interaction interview ; The feature dependency graph CoFDG is a tuple (n, p), wherein n is a set of feature nodes, and p is a set of pointers for pointing to feature nodes; storing modeling features and features between features in the CoFDG Dependencies; the hash table...

Abstract

The invention provides a CRDT-based real-time collaborative editing method for supporting feature CAD models, which links newly inserted modeling operations into a double linked list in full order inboth local operation processing and remote operation processing. The invention can support multi-user real-time collaborative editing and sharing CAD model under large-scale peer-to-peer network environment. The invention can ensure the consistency of the CAD model of the multi-user cooperative editing and the consistency of the CAD modeling history. The invention can provide good user interaction.

Description

technical field [0001] The invention belongs to the field of information technology, and relates to a computer-supported collaborative work method, in particular to a CRDT-based real-time collaborative editing method supporting feature CAD models. Background technique [0002] Real-time collaborative CAD system is an important application field in computer-supported collaborative work. The real-time collaborative CAD system is different from the traditional distributed system, allowing designers in different geographical locations to edit the same CAD model at the same time, and each collaborative site stores a copy of the shared CAD model. Consistency maintenance of shared CAD models presents a challenge as multiple users can simultaneously edit copies of the shared CAD model. [0003] The Commutative Replicated Data Type (CRDT) method is an emerging consistency maintenance method in recent years. The main idea is to map the operation objects into the internal data struct...
