3D animations are digital images that create the illusion of depth and movement. Unlike traditional 2D animations, which use flat images, 3D animations involve modeling objects in a three-dimensional space. This allows for more realistic visuals, as objects can be rotated and viewed from different angles. To create 3D animations, artists use specialized software to design characters, environments, and effects. These animations are widely used in various fields, including film, video games, and virtual reality. The process involves several steps, such as modeling, texturing, rigging, and rendering, to bring the animated scenes to life.
