ABSTRACT

With the development of the Internet, Metauniverse, and graphics processing technique, video games and immersive virtual social contacting service are largely propelled. Therefore, the quality of 3D virtual character models is getting more and more important—higher fidelities of screens have largely promoted the demand for finer 3D character models. However, the cost and time efficiency of traditional modeling relied on human artist can hardly support such a great demand, and will potentially slow down the development of video game and metauniverse industry. In an effort to improve this situation, this paper conducted research about 3D virtual characters reconstructions through NeRF and illustrated the principals and functions of NeRF. Using two different datasets (Doll Photos Dataset and Real-Human Photos Datasets), this paper evaluated the NeRF model and provided researching advice for future research about dataset building and possible directions.
