Method and system for realizing distributed virtual reality and visualization on mobile device

Abstract

The invention discloses a method and a system for realizing distributed virtual reality and visualization on a mobile device, which belong to the technical field of graph and visualization. The method is as follows: 1, communication connection between the mobile device and a virtual reality and visualization server is established; 2, an interactive operation request command is resolved into an interactive command for a virtual reality and visualization system by the mobile device; 3, the interactive command is transmitted to the virtual reality and visualization system by the mobile device; 4, corresponding calculations are executed by the virtual reality and visualization system according to the interactive command, and an execution result is sent to the mobile device; and 5, the received data is decoded by the mobile device to show virtual scene and visualization results. The system comprises a client installed on the mobile device, and a server on the virtual reality and visualization server; and the mobile device is connected with the virtual reality and visualization server through network. The invention can implement high-precision three-dimensional scene browsing and roaming on common mobile devices, and greatly improves the sense of reality for drawing.

Description

technical field [0001] The invention relates to a method for realizing distributed virtual reality and visualization on a mobile device, and belongs to the technical fields of virtual reality and technology, graphics and visualization technology, and network communication. Background technique [0002] In today's society, mobile devices and various application software on the mobile devices are becoming more and more popular. At present, mobile computing chips on mobile devices are like the latest version of the latest embedded ARM architecture, the Cortex-A9 version, but the maximum memory capacity is 512M, and the core frequency is up to 2GHZ, but its static storage and dynamic capabilities and computing performance are comparable to those traditionally based on X86 The framework computers and servers are far from each other, especially the special model with the most powerful GPU performance under this architecture is Mali-T604, its parameters support OpenGL ES 1.1 / 2.0, t...

Problems solved by technology

At present, mobile computing chips on mobile devices are like the latest version of the latest embedded ARM architecture, the Cortex-A9 version, but the maximum memory capacity is 512M, and the core frequency is up to 2GHZ, but its static storage and dynamic capabilities, as well as computing performance and traditional X86-based The framework computers and servers are far from each other, especially the special model with the most powerful GPU performance under this framework is Mali-T604, its parameters support OpenGL ES 1.1 / 2.0, the limit of geometric processing capacity is tens of millions per second, and pixel filling The rate limit is 100 megabytes per second, which can only support some lightweight 3D digital entertainment, but in the virtual reality and visualization system, a virtual scene may contain tens of millions of patches, and may also contain a large number of Physical models, vector line drawings, or other virtual reality content such as lighting, waves, sky, etc., the calculation and rendering of these huge data has far exceeded the computing and rendering capabilities of mobile devices, and how to store these massive data is also facing challenges
