3D animation is a digital art form that creates the illusion of movement by generating and manipulating objects in a three-dimensional space using computer software. Unlike traditional 2D animation, where characters and environments are flat, 3D animation involves depth, giving visuals a more lifelike and immersive appearance. The process typically includes modeling (building 3D objects), rigging (creating a skeleton for movement), animating (bringing motion to the model), texturing (applying surface details), lighting, and rendering (producing the final image or video). Commonly used in films, video games, architecture, simulations, and virtual reality, 3D animation allows artists to create complex scenes and realistic motion that captivate viewers and enhance storytelling.
