Ultra-high-speed real-time rendering method for virtual reality

Abstract

The invention relates to a virtual reality superspeed real-time rendering method, and the method comprises the steps: A, building environmental parameters to build an image model, carrying out the interactive control of a camera, enabling the near peripheral region and far peripheral region of a view field to be divided into three rendering regions with different resolutions, and enabling the built image model to generate a Perlin noise height field; B, carrying out the sampling through a projection grid, and building a virtual figure; C, obtaining the data of top points in the virtual figure; D, enabling the data of all top points to be mapped in a coordinate system; E, calculating texture coordinates; F, loading the texture coordinates; G, mixing various types of texture colors in all rendering regions, and completing the rendering. According to the invention, the method employs the rendering regions and distributes different resolution proportions to match with different visual sensitivity in the view field of a user, reduces the operation cost by several times, saves the operation resources and power of a computer, and achieves the real-time superspeed rendering. The method draws a water surface with a real effect through the pixel rendering and top point rendering.

Description

technical field [0001] The virtual reality technology of the present invention, in particular, relates to an ultra-high-speed real-time rendering method for virtual reality. Background technique [0002] Virtual reality technology (referred to as VR), also known as spirit world technology, is an advanced computer human-machine interface with immersion, interactivity and conception as its basic features. It comprehensively utilizes computer graphics, simulation technology, multimedia technology, artificial intelligence technology, computer network technology, parallel processing technology and multi-sensor technology to simulate the functions of human sensory organs such as vision, hearing and touch, so that people can immerse themselves in computer-generated In the virtual world, and can interact with it in real time through language, gestures, mouse and keyboard, etc., creating a humanized multi-dimensional information space, which is a developing new technology with far-re...

Problems solved by technology

Some experts at home and abroad have proposed many algorithms and technologies for generating and rendering water surfaces. Although these technologies can generate realistic water surface effects, they often cannot meet the speed requirements of real-time rendering; Very simple modeling and lighting model, the water surface effect drawn is not very realistic
