Editing method for decentralized collaborative three-dimensional modeling

The invention relates to an editing method for decentralized collaborative three-dimensional modeling. The problems that decentralized setting, multi-person collaborative editing and the like are not supported in existing three-dimensional modeling are solved. Comprising the steps of 1, representing a three-dimensional model; step 2, initializing modeling; step 3, incrementally updating the code, if there is a newly added modeling operation compared with the last synchronization, storing the incremental operation and synchronizing the incremental operation to other clients, executing step 4, and if there is no newly added modeling operation, retaining the current state until the newly added modeling operation; step 4, if all the clients perform increment operation on different model elements or the same model element in different states, executing step 5, and if at least two clients perform increment operation on the same model element in the same state, executing step 6; 5, combining all incremental operatio
