WiMi Hologram Cloud Inc. (NASDAQ:WIMI) is developing a real-time dynamic simulation-based virtual digital human rendering technology. The technology requires high-precision modelling and dynamic control of digital characters, including the establishment of the skeletal system, the simulation of physical properties such as muscles, skin, hair, etc., and the calculation of human kinematics and motion capture. The technology is now widely used in the fields of gaming, virtual reality, augmented reality, human-computer interaction, education, advertising and so on.
