3D animation is a technique used to create digital animations that involve the use of three-dimensional graphics. It involves creating a series of images that give the illusion of movement and depth, allowing for the creation of highly realistic and lifelike animations. The process of creating a 3D animation involves several stages, including modeling, texturing, rigging, animation, and rendering. First, the objects and characters to be animated are created as 3D models using specialized software. The models are then textured with materials and given lighting to create a realistic appearance.
