Have you heard of Luo Tianyi and "Dancing with Scallions"? With the emergence of virtual idols, virtual human industry has become a new target for capital betting. Public data shows that as of September this year, the investment and financing amount of domestic virtual digital human track has exceeded that of last year, reaching 2.49 billion yuan. In 2021, the investment and financing amount of virtual digital human related enterprises will be about 1.971 billion yuan, while in 2015, the statistics will be only 33 million yuan, with a compound growth rate of 97.71% in six years. The major technology giants also choose to "show their muscles" in the field of virtual human: foreign meta and Microsoft, domestic Tencent, Ali, Baidu, Kwai and NetEase have all invested heavily in the layout. In addition to virtual idols, virtual humans have been used in many scenes. "The value of virtual human is not just the virtual idol of 'not collapsing houses'." Feng Zheng, Vice President of Shunwei Capital, told the surging journalists. "The biggest application scenario of virtual human is virtual identity and interactive interface: the former is a personal image in the virtual world; the latter is equivalent to a robot in the virtual world, which is driven by AI and interacts with humans." The meta universe market, like the portal website in the early stage, uses academic interpretation to view virtual people, which refers to virtual images with anthropomorphic characteristics that exist in the non physical world in the form of pictures, videos, live broadcasts, etc. through CG, motion capture, VR and other technologies. They can also be called digital people. Yang Dong, the technical director of Unity China platform, told the surging reporter that virtual human technology has been developing for a long time. The reason for this year's attention is due to the emergence of entertainment virtual human images such as Liu Yexi and Luo Tianyi, and the rise of the concept of "meta universe". The growing demand for customized personal virtual images has brought the virtual human industry into the public's view. "The virtual human first became popular in 2017, then went through a period of exploration, and gradually became commercialized in these two years." Feng Zheng told the surging journalists. "The concept of the meta universe is vague as a whole, among which the virtual digital person is the most contacted and understood by everyone. Whether it is a virtual idol or a virtual anchor, it is relatively more visual and specific, so it is widely concerned by capital." According to the prediction of Ai Media, the domestic industrial market driven by virtual human will reach 640.27 billion yuan in 2025. How on earth was virtual human created? Saito Fei, the head of Netease Fuxi virtual interaction technology, revealed to the reporter that to create a virtual person, you need to consider the scene, audience, hardware platform that carries the virtual person, and the upper and lower limits of cost investment. These restrictions comprehensively determine the style of painting and art quality standards of the virtual person, and delineate the basic scope of the human design. On this basis, further determine the role name, basic setting, and main visual design. Saito mentioned that virtual human manufacturing is still a complex technical system, which needs to include cross discipline, cross domain and cross functional collaboration, such as art (modeler, binder, animator), development (client development, technical art, visual effect development), algorithm (voice generation, animation drive), etc. When different fields move forward together around the same goal, how to effectively unify
