Motion capture
Video games often use motion capture to animate athletes, martial artists, and other in-game characters. As early as 1988, an early form of motion capture was used to animate the 2D main character of the Martech video game "Vixen", which was performed by model Corinne Russell. Motion capture was later notably used to animate the 3D character models in the Sega Model 2 arcade game "Virtua Fighter 2" in 1994. In mid-1995, developer/publisher Acclaim Entertainment had its own in-house motion capture studio built into its headquarters. Namco's 1995 arcade game "Soul Edge" used passive optical system markers for motion capture.
