Research on the Real-Time Rendering of Global Illumination of the Virtual Reality System Based on Cloud Computing

The new technology of global lighting real-time rendering is studied based on virtual reality system. By tracking and rendering the global lighting image of virtual reality system, the real-time processing ability of global lighting real-time rendering scheduling of virtual reality system image processing platform is improved. A real-time rendering algorithm of global illumination in virtual reality system based on cloud computing similarity measurement is proposed. Through the natural stratification of the global lighting scene image of the virtual reality system and retaining the basic information of the original image, in the global lighting real-time rendering algorithm, the global distribution field of the virtual reality system is matched, the template feature matching method is used to detect the light intensity, and the cloud computing technology is used for the global rendering data fusion filtering. The similarity between the global light field and the candidate distribution field of the virtual reality system can obtain the maximum response. The similarity measurement of global light field in virtual reality system is realized, and the ability of real-time rendering of global light in virtual reality system is improved. The simulation results show that the algorithm can improve the efficiency of rendering tracking, and the lower the similarity, the less the traditional rendering technology is easy to fall into the local minimum, and the global lighting rendering ability of virtual reality system can be improved by using this algorithm to render the global light of virtual reality system in real time.
