System capable of realizing immersive virtual reality over mobile platforms

Abstract

The invention relates to a system capable of realizing immersive virtual reality over mobile platforms. A DirectX3D rendering technique is adopted to perform distortion correction and distortion zooming on images rendered by virtual three-dimensional scenes via a Pixel Shader , the images are segmented and drawn on a left and right binoculus screen of HMD (helmet-mounted display) equipment, and an updating frequency of more than 60 frames per second is kept; position information and facing information of the HMD equipment are acquired from a sensor and used for head tracking, and coordinate and rotating quaternion information are fed back to an application program via a message port; interaction between a client end and a server end is realized via a wireless communication technology. The system has the advantages that one product only needs to be developed for once, reality is enhanced, virtual objects not existing in the real environment are generated via a computer graphic technology and a visualization technology, the virtual objects are accurately 'placed' in the real environment via the sensing technology and are integrally mixed with the real environment by the aid of displaying equipment.

Description

technical field [0001] The present invention relates to virtual reality technology. Background technique [0002] Virtual reality, referred to as VR technology, is to use computer simulation to generate a three-dimensional virtual world, providing users with simulations of vision, hearing, touch and other senses, allowing users to observe in a timely and unlimited manner as if they were on the scene. things in three dimensions. [0003] At present, in the world, there are mainly two engines that support mobile Internet and virtual reality at the same time. They are the Unreal3 engine of the American Epic Company and the Unity3D engine of the Danish Unity Technology Company. [0004] The Unreal3 engine is the leader of traditional PC and home console platforms, and thousands of games and virtual reality applications are developed using this engine. When technology develops into the era of mobile Internet, the Unreal3 engine has also issued corresponding engine authorization...

AI Technical Summary

Problems solved by technology

However, VRP's virtual reality 3D engine has a very large gap with foreign virtual reality engines in terms of technology: it does not support point coloring, and the UV layer only supports two layers.

Does not support UV animation, it is a waste of textures to achieve a flowing effect, and there are few ways to superimpose textures

Moreover, the entire platform does not provide customers with any interfaces that programmers can intervene in, and does not support any plug-ins written by customers themselves, etc. Defects also put VRP at a disadvantage in the competition with foreign engines.
