Behind the stunning visual effects of 'Ne Zha: The Birth of the Demon Child', a silent magnetic revolution is quietly unfolding. From the particle effects of Huntianling to the quantized rendering of Nezha's out of body spirit, from the dynamic simulation of mountains and rivers to the physical modeling of Aobing Ice Dragon scales, the technical principles related to magnets are deeply integrated into every aspect of special effects production in digital form. This magnetic application that spans the physical world and digital space is redefining the technological boundaries of the animated film industry.
