Computer game animation has advanced significantly since early 2D games like Pong. Gamers now demand highly realistic and believable characters. Motion capture is a key technique used to create realistic animations, capturing the movements of actors and applying them to digital characters. While motion capture improves realism, animators still need to refine movements to convey different emotions. Achieving realistic facial expressions and crying remains challenging. Advanced techniques are also required to capture animal movements. Overall, motion capture has greatly improved character animation, but animators still play an important role in bringing digital characters to life.

- 1. Explore current technical challenges for computer games: Advanced character animation (including motion capture) By Abi Belsham
- 3. "Almost every video game today uses character animation. It’s become a standard element in modern entertainment software" Mark Stuart (video games designer for Bionic Games)
- 4. Animation has developed and moved on from the traditional ways of using a pen & pencil.
- 5. Video games have evolved since the early days of the two-dimensional table tennis game ‘Pong’, which was first released as an arcade game in 1972.
- 6. These days, gamers demand a far more immersive gaming experience involving fully believable and realistic characters who inhabit elaborate worlds and are involved on complex missions.
- 7. Computer game animations are created in loops, with action sequences starting and ending with the same pose, which is looped to the next action sequence. A seamless transition between one loop cycle and the next is necessary. Animated characters need to carry out different types of actions, such as walking, running, completing tasks and fighting.
- 8. There is a limited list of actions for computer game animation characters: Idle Walk Run Jump Crouch Attack Get hit Death
- 9. Gamers need to identify with, and be sympathetic to, the characters. By creating empathy for the animated character, gamers become more involved in the game. Gamers must believe in the world of the game and not put off by any strange facial animations or uneven motion of the animated character. The animated character will need to be seen from all angles in the game so it must look correct from all points of views. Animated characters must seem real.
- 10. Different techniques are used in character animation, such as Key framing, Skeletal Animation and Motion Capture. Motion Capture is an advanced animation technique that speeds up the development time of skeletal animation and increases the level of realism. Motion Capture is where the motion of a living person or animal is captured using video cameras and sensors attached to key points on the real persons body. eg computer game Battlefield 4:
- 11. During the motion capture process, a real person acts out the required sequence of actions as if they were the computer character. The actors movements are recorded to a computer through video cameras and sensors. The movements are then applied to the animated computer character. Developments in the use of motion capture for computer games are ongoing. For the game L.A. Noire, the actors were recorded by 32 cameras to capture facial expressions from every angle. eg computer game L.A. Noire
- 12. Animal characters are also required for video game characters. Horses play important roles in games such as Call of Duty and Red Dead Redemption and motion capture is used to obtain realistic movement of the animal.
- 13. Obtaining good acting performances from the motion capture actor is becoming increasingly important. When animals are used as the motion capture actor, there are additional challenges: getting the animal to perform when required or to remain still can be hard and the sensors are often shaken off their bodies. The actor’s body and facial structure may be very different to the animated character. Animators are required to bring the animated characters to life, to make sure the movements of the actor look good when performed by the animated characters. Improving the detail, quality and realism of facial animation is an ongoing challenge. Facial animations need to come close to conveying realistic human likeness and although facial capture will reproduce a smile, it still takes an animator to make it a sarcastic smile or a bashful smile. Crying is rare in games – fluid simulation is extremely challenging.
- 14. Computer game animation has taken big leaps forward through the use of technology like motion capture. Achieving realism isn’t cheap and costs could get out of control with the ongoing drive to increase the quality of the animated characters. Smart phones and tablets have their own challenges although mobile isn’t that far away from the current games consoles. New challenges lie ahead now that the language of cinema is being incorporated into the game, a good example being Assassin’s Creed IV: Black Flag. Animators still have a really important job to do, regardless of the technology used.
- 15. "Though our tools and technology are constantly changing, the core of what we do as animators remains the same." Martine Quesnel (animator at Ubisoft) (Ref. 1)
