Motion capture
Motion capture is the process of recording the movement of objects or people. It is used in military, entertainment, sports, medical applications, and for validation of computer vision and robotics. In filmmaking and video game development, it refers to recording actions of human actors and using that information to animate digital character models in 2D or 3D computer animation.
About Motion capture in brief
Motion capture is the process of recording the movement of objects or people. It is used in military, entertainment, sports, medical applications, and for validation of computer vision and robotics. In filmmaking and video game development, it refers to recording actions of human actors, and using that information to animate digital character models in 2D or 3D computer animation. When it includes face and fingers or captures subtle expressions, it is often referred to as performance capture. In motion capture sessions, movements of one or more actors are sampled many times per second. This animation data is mapped to a 3D model so that the model performs the same actions as the actor. Camera movements can also be motion captured so that a virtual camera in the scene will pan, tilt or dolly around the stage driven by a camera operator while the actor is performing. This allows the computer-generated characters, images and sets to have the same perspective as the video images from the camera. Video games often use motion capture to animate athletes, martial artists, and other in-game characters. This has been done since the Sega Model 2 arcade game Virtua Fighter 2 in 1994. Star Wars: Episode I – The Phantom Menace was the first feature-length film to include a main character created using motion capture. The Great Goblin, the three Stone-trolls, many of the orcs and goblins in the 2012 film The Hobbit: An Unexpected Journey, and Smaug were created usingmotion capture.
Disney’s Cars was animated without motion capture, and only two of the nominees for the 2006 Academy Award for Best Animated Feature, Out of the Three, used motion capture and only Disney·Pixar’s Ratatouille was animated with motion Capture. The Lord of the Rings: The Two Towers was streamed as a real-time motion capture system to utilize a computer generated skin of Andy Serkis’ Gollum Sagolle, a character from the film Ratouille, appears as a stamp in the film. Since 2001, motion capture is being used as a labelling method for the film No–100% Pure Animation, with the film’s labelling appearing as the film is being performed. The end result of which is that the animated character replicates exactly the live-action movements of the actor, However, this process takes a considerable amount of time and effort. The method may be contrasted with the older technique of rotoscoping, as seen in Ralph Bakshi’s The Lord Of The Rings and American Pop. This method works by tracing over a live- action actor, capturing the actor’s motions and movements. Namco’s 1995 arcade game Soul Edge used passive optical system markers for motion capture in the game. Despite its poor box-office intake, supporters of motion capture technology took notice of the technique, and Total Recall had already used the technique to create the X-ray scanner in the x-ray scene of the film Total Recall.
