Animation in game graphics serves multiple purposes, including creating realistic and immersive environments, adding visual appeal and entertainment value, and enhancing the gameplay experience.

Procedural animation is not as commonly used in game graphics as keyframe animation, motion capture, and sprite animation.

Keyframe animation offers precise control over the animation, is relatively easy to create, and is computationally efficient, making it a popular choice for game graphics.

Spline interpolation is not as commonly used in game graphics as linear interpolation, cubic interpolation, and Bezier interpolation.

Motion capture is primarily used in game graphics to create realistic and natural-looking animations.

Acoustic motion capture is not as commonly used in game graphics as optical motion capture, inertial motion capture, and magnetic motion capture.

Procedural animation offers dynamic and interactive animations, is relatively easy to create, and is computationally efficient.

Fluid simulation is not as commonly used in game graphics as inverse kinematics, ragdoll physics, and particle systems.

Sprite animation offers computational efficiency, relative ease of creation, and a wide range of artistic styles.

3D sprites are not as commonly used in game graphics as hand-drawn sprites, pixel art sprites, and vector art sprites.

3D graphics are primarily used in game graphics to create realistic and immersive environments.

Heightmap modeling is not as commonly used in game graphics as polygonal modeling, NURBS modeling, and voxel modeling.

2D graphics offer computational efficiency, relative ease of creation, and a wide range of artistic styles.

Procedural graphics are not as commonly used in game graphics as pixel art, vector art, and bitmap graphics.

Real-time rendering offers dynamic and interactive environments, computational efficiency, and relative ease of implementation.
