Types of Motion Capture Used for Game Animation
Motion capture is not a one-size-fits-all solution. Game developers often choose different types of mocap based on their specific needs:
1. Optical Motion Capture
This is the most widely used mocap technique in the gaming industry. Optical motion capture systems use multiple infrared cameras to track reflective markers placed on the actor’s body. By triangulating the position of each marker in three-dimensional space, the system creates an accurate digital representation of the actor’s movements. Optical mocap is favored for its high precision and is ideal for capturing everything from basic character movements to intricate fight sequences, making it the go-to solution for game cut scene animation and large-scale production projects.
2. Full-Body, Facial, and Hand Mocap Systems
While full-body motion capture records the entire body’s movement, facial mocap focuses on capturing intricate facial expressions and lip movements. Hand mocap, on the other hand, tracks the movements of fingers and wrists, crucial for scenes where characters interact with objects or perform detailed hand gestures. The ability to combine these different types of motion capture data allows game developers to create fully animated characters that are lifelike and emotionally engaging.
The impact of Vicon’s mocap systems on clinical gait analysis is profound, providing clinicians with the tools they need to make informed decisions and improve patient outcomes.

4. Versatility
Motion capture technology is not just limited to character animation. It can be used for creating cut scenes, simulating camera movements, animating environmental elements, and even controlling vehicles or animals. Developers can also leverage mocap for virtual production, creating dynamic scenes where character and camera movements are captured simultaneously. This versatility makes motion capture an invaluable tool in all stages of game development.
Motion Capture Workflow in Game Development
Implementing motion capture in game development involves a series of steps to ensure the final product is seamless and polished. Here’s an overview of the typical motion capture workflow:
1. Pre-Production
The pre-production phase is all about planning and preparation. Game developers decide on the specific movements and scenes they want to capture, design the motion capture stage, and select the actors. It’s crucial to set up the stage with the correct cameras and calibrate the motion capture system to ensure accurate recordings. This phase also involves scriptwriting, rehearsals, and testing to iron out any technical or creative issues before the actual recording begins.
2. Production
During the production phase, actors perform the planned scenes while wearing motion capture suits equipped with reflective markers. Multiple high-fidelity cameras from Vicon’s Valkyrie or Vero series capture the markers’ movements in real time, generating digital data for each frame. In some cases, developers may need to adjust the mocap system on the fly to capture additional details or refine specific movements. Real-time monitoring and feedback allow the team to ensure they’re capturing the desired performances.
3. Post-Production
The captured motion data is often raw and contains errors or noise. In post-production, animators use software like Vicon’s Shōgun to clean and refine this data. This involves correcting inconsistencies, filling in gaps, and smoothing out rough edges. Once the data is cleaned, it is applied to digital models within 3D animation software, where further adjustments are made to ensure the animations align with the game’s visual style and gameplay mechanics.
4. Integration into Game Engines
The final step in the workflow is integrating the refined mocap data into a game engine like Unity or Unreal Engine. Vicon’s Shōgun software provides seamless integration with these popular engines, allowing developers to retarget mocap data to game characters quickly.
