What is a primitive object in animation?

In animation, a primitive object refers to basic geometric shapes, such as spheres, cubes, cylinders, and planes, that are used as the foundational building blocks for more complex models. These objects are often manipulated and combined to create characters, environments, and other visual elements in both 2D and 3D animation. By utilizing primitives, animators can streamline the modeling process and focus on refining details in their creations.
