Embodiment 1

[0031] The invention is a method for GPU-BOX server VR optimization.

[0032] The first step is to support multiple graphics cards in VR sli. By adding graphics cards, the rendering performance can be increased.

[0033] That is, graphics card 0 and graphics card 1 take turns to render the nth frame and the n1th frame, but the cpu must be submitted fast enough, because the cpu still has to submit two drawcalls, and the cpu cannot become a bottleneck.

[0034] Let graphics card 0 and graphics card 1 be responsible for drawing the left and right eyes, and the cpu provides exactly the same drawcall for the two graphics cards, because the things drawn in the two eyes of VR are basically the same, except for the perspective matrix. VRworks, through its application programming interface, implements a set of draw calls to broadcast to multiple graphics cards, and can set different perspectives for different graphics cards. In this way, one cpu drawcall is for both eyes, and the two eyes ar...

Abstract

The invention discloses a VR optimization method of a GPU-BOX server. The method comprises that S1) the GPU resource is expanded effectively via support of multiple VR sli video cards, and resource insufficiency is alleviated; S2) multi-resolution rendering is used to reduce the resolution in edge positions; and S3) asynchronous time warp is used to make users less uncomfortable. According to the method, VR is optimized to enhance the practicality of VR greatly, reduce the development period of a VR product, reduce the development cost of products, and prompt development of VR products.

Description

Technical field [0001] The present invention relates to the technical field of GPU servers and virtual reality, in particular to a method for GPU-BOX server VR optimization. Background technique [0002] Virtual reality (VR for short) refers to a technology that uses a computer graphics system and various reality and control interface devices to provide an immersive feeling in an interactive three-dimensional environment generated on a computer. Among them, the computer-generated, interactive three-dimensional environment is called a virtual environment (ie Virtual Environment, VE for short). Virtual reality technology is a computer simulation system technology that can create and experience a virtual world. It uses a computer to generate a simulation environment, and uses multi-source information fusion interactive three-dimensional dynamic scene and entity behavior system simulation to immerse users in the environment. [0003] VR (virtual reality) technology can be widely used...
