Problems solved by technology

For VR application scenarios, the output frame rate is a key indicator. When the output frame rate is insufficient, it will cause users to feel dizzy.
On the other hand, even if the performance of the GPU is sufficient, because the calculation load of graphics rendering is heavy, this will cause the VR device to consume a lot of current and cause continuous heating problems

Abstract

The invention discloses a graphic rendering method and device for virtual reality. According to the invention, a first image corresponding to spatial position information and directional information is generated through rendering according to a first angle resolution based on the acquired spatial position information and the directional information of a head-mounted virtual reality device. According to acquired position information of a human eye fixation point on a display screen, a second image corresponding to the human eye fixation point is generated through rendering according to a second angle resolution. A third image is generated through combination of the first image and the second image. According to the invention, when rendering is performed on the virtual reality image, the adopted first angle resolution and the adopted second angle resolution are comparatively low angle resolutions, so that the calculation amount of a GPU can be reduced effectively and image rendering efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of virtual reality, in particular to a method and device for rendering graphics in virtual reality. Background technique [0002] Existing virtual reality (referred to as VR) devices need to support higher and higher display resolutions, from 1k, 2k to 4k, and even 8k, 16k screen resolutions in the future, so as to eliminate the screen door effect of the display and enhance virtual reality. The authenticity of the display effect in the environment. But on the other hand, the higher and higher display resolution poses an increasing challenge to the 3D graphics rendering capability of a graphics processing unit (GPU for short) of a VR device. When the GPU performance is insufficient, a compromise needs to be made between the graphics rendering quality and the graphics rendering output frame rate, either reducing the graphics rendering quality requirements, or reducing the rendering output frame rate...
