VR three-dimensional data rendering system and its method

Abstract

The invention discloses a three-dimensional data rendering system for VR and a method thereof. The system comprises a server side and a client side. The server side renders a reality scene and transmits the reality scene to a display device of the client side for display. The client side comprises a head-mounted display device and a mobile client side. The server side comprises a virtual reality engine. The mobile client side is mounted on a smart mobile device held by a user. The smart mobile device interacts with the server side through wireless communication. The smart mobile device is an Android mobile phone. Through combination of the method, the defects that in the prior art, the display delay of an application is very high and a display rendering mechanism does not apply to the VR are avoided.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a VR three-dimensional data rendering system and method thereof. 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] Rendering is a common processing method under virtual reality technology. Under the current Android rendering system, each application will be allocated three display buffers to match the rendering speed of the GPU and the display speed of the display to prevent screen tearing. Obviously, such a triple buffering mechanism increases the delay time from the GPU to the final display. [0004] On the other hand, different display screens will also bring differ...

Problems solved by technology

Obviously, such a triple-buffering mechanism increases the delay time from the GPU to the final display

[0004] On the other hand, different display screens will also bring different delay times, TFT screens have a delay of about 20ms, and OLEDs only have a delay of 5ms

[0005] Therefore, Android applications are directly used in the VR environment, and the display delay of the application is very high. The current display rendering mechanism is not suitable for VR.
