The technology employed for creating almost lifelike animations in films is computer-generated imagery (CGI). This process uses advanced algorithms and software to create realistic visual effects and animated characters that blend seamlessly with live-action footage. CGI involves manipulating 3D models, textures, and lighting to achieve photorealism. Techniques like motion capture enhance realism by tracking actors' movements and translating them into digital models. Overall, CGI has revolutionized the film industry, allowing for imaginative storytelling and stunning visual experiences that captivate audiences.
