New York Times: The three-dimensional imaging techniques of the movies are being used to improve athletic performance. Motion capture produces a 3D image on a computer using a combination of advanced sensors, biomechanics, orthopedic research, and animated-film technology such as that used in the film Avatar (2009). The images generated, which can be viewed from any direction, provide a wealth of data regarding limb angles, ball speeds, and g-forces. Some of the innovative uses of the new technology include sports players studying their peak performances to improve their technique and avoid injury, dancers in different locations being able to practice with each other using 3D re-creations, and coaches working remotely with teams by watching them perform drills in three dimensions in another location.
