Keyframes in 3D animation are core frames that define the start and end states of a motion or transformation, acting as anchors for an object’s position, rotation, or properties at critical moments.
They mark essential poses: For example, animating a character waving would use keyframes for the hand’s highest and lowest positions.
Animation software then auto-generates intermediate frames between keyframes via interpolation, creating smooth, continuous movement.
This method streamlines workflow—artists focus on key poses first, then refine details, making complex animations manageable for both beginners and professionals.
