Problems solved by technology

[0004] When the existing method performs rendering simulation for high-model models (models with a large number of faces), due to the large number of model faces, the picture will appear stuck, which will greatly affect the operation
[0005] Solve the stuttering problem by anti-aliasing, using low-model (model with fewer faces), etc., but this will affect the user's visual effect
[0006] Using s l i / crossfire technology for rendering, in theory, each additional graphics card can increase by 80%, but as the number of graphics cards increases, the improvement effect will reach the bottleneck

Embodiment 1

[0035] Such as Figures 1 to 3 As shown, a preferred embodiment of a visualization method of a manufacturing process based on a virtual simulation environment of the present invention includes:

[0036] The S1 server, the left-eye client and the right-eye client form a communication network;

[0037] S2. The server sends synchronization information to the left-eye client and right-eye client at the same time. The synchronization information includes camera matrix information and time stamps. The left-eye client and right-eye client change the current camera matrix information to the server's camera Matrix information, after the camera matrix information of the left-eye client and right-eye client is set, feed back the current synchronization information to the server;

[0038] The S2 server records the current synchronization information. The two clients need to send the current synchronization information to the server. The server verifies whether the synchronization informa...

Embodiment 2

[0059] A preferred embodiment of the visualization system of a manufacturing process based on a virtual simulation environment in the present invention, in order to realize the method described in the above-mentioned embodiment 1, includes:

[0060] Servers include:

Abstract

The invention discloses a manufacturing process visualization method and a system based on a virtual simulation environment, which are designed for efficiently displaying a virtual simulation environment in real time. The visualization method of the manufacturing process based on the virtual simulation environment of the invention comprises the following steps: synchronizing the information of thecamera position, the angle and the angle of view of the two clients, and verifying the synchronization process message; performing synchronous verification between a client and a server; the server obtaining the control information through an external input device, and if no input is obtained, the server directly proceeds to the next step; sending it to two clients to ensure client state synchronization and client render data; the client processing the rendering data according to the control of the server and the synchronization information, and sending the rendering data to the server in real time. The invention improves the rendering performance, also more effectively improves the use of multi-graphics card.

Description

technical field [0001] The invention relates to the field of virtual reality simulation, in particular to a visualization method and system for a manufacturing process based on a virtual simulation environment. Background technique [0002] Virtual manufacturing technology (virtual manufacturing technology, VMT) is based on virtual reality and simulation technology. It uniformly models the product design and production process, and realizes the entire life cycle of the product from design, processing and assembly, inspection and use on the computer. Simulation and emulation. [0003] Based on virtual assembly technology (Virtual Assembly, VA) for development. The so-called virtual assembly is to use virtual reality technology to evaluate and optimize the assembly process such as product assembleability, disassembly, collision interference in assembly process, assembly sequence and assembly path interactively by operators in a virtual environment. Using virtual reality deve...
