A subset of animation that utilizes three-dimensional models and environments manipulated over time within a digital space. This involves creating and animating virtual objects with depth, volume, and perspective. Techniques include keyframe animation, motion capture, and procedural animation to control the movement and deformation of 3D characters, objects, and camera perspectives. 3D animation is widely used in feature films, video games, architectural visualizations, and scientific simulations, offering a sense of depth and realism.
