Problems solved by technology

In this technical solution, most of the system burden is concentrated on the client, and the image data transmission is still relatively high for the current Internet conditions (usually the image size is around 10KB-100KB, and for the 1Mbps access speed of ordinary broadband, it needs 0.7s or so), its system response speed has a certain gap compared with traditional rendering

Embodiment Construction

[0028] Such as figure 1 As shown, a 3D remote rendering system based on image transmission includes an interactive server end and a client end, and the server end is provided with a model file management unit 2, a 3D rendering engine unit 4, an image codec compression unit 9 and a network transmission unit 10.

[0029] Model file management unit 2, when the system receives a request from the user to browse a certain model, this unit is responsible for reading the model storage location information from the database 1 and then reading the 3D model file, because the I / O operation contained in this unit is to improve the system The bottleneck of response speed, so in this unit, the mechanism of pre-reading and caching some model files is used for optimization;

[0030] The 3D rendering engine unit 4 analyzes the model files read into the memory and generates scene data that can be directly rendered. Currently, the rendering engine is compatible with standard model files in the V...

Abstract

The invention discloses a three-dimension remote romance system, based on graph transmission, which comprises interactive server terminal and user terminal. Wherein, the server terminal has mode file manage unit, three-dimension romance engine unit, graph code decode compress unit, and network transmission unit; the user terminal has network transmission unit and user interactive unit; when the server terminal receives the browse request of user terminal via the network transmission unit, the mode file manage unit reads the mode file that requesting browse; using three-dimension romance engine unit to romance generate graph data, via the graph code decode compress unit to be compressed, and via network transmission unit, to be sent to the user terminal; user terminal decodes the data of compressed graph, to display it via user interface. The invention uses progressive transmission, multistage delay memory, and the prediction based on user interaction to realize the balance between high real-time property and high accurate browse, to support quick beautiful romance effect to general user.

Description

technical field [0001] The present invention relates to a remote rendering display technology of a three-dimensional model, in particular to a three-dimensional remote rendering system and method based on image transmission. Background technique [0002] At present, more and more websites on the Internet provide users with real and beautiful immersive virtual reality display through high-precision 3D models. A single 3D model of ordinary size with medium precision may generate a file size of 10-100Mb, so in many cases, a network rendering display technology that can ensure real-time user interaction and display effect is required. [0003] The traditional transmission method used in the past is to divide the data into data packets according to the byte order and then send them to the receiving end through the network, and the receiving end must receive all the correct data packets before they can assemble the complete data and read and analyze it. Among the commonly used We...
