A rig in 3D animation is a structure that simplifies the animation process. While simple animations can be done without a rig, more complex movements, like squash and stretch or rotation, require a rig, typically consisting of an armature. Armatures are essential because they provide specific tools in Blender's pose mode that streamline the animation workflow, making it easier to manage and animate. Although Blender's development is evolving, armatures remain the most efficient way to rig and animate in Blender.
