Photographs by Malika Khurana Methodology The 3-D scene was created based on photographs captured by The New York Times during the game. The positions of the players, the ball trajectory and the player paths were determined using custom software created by The Times. The software uses computer vision to detect and track the players and the ball. It also uses 3-D projections to manually map those elements to their real-world coordinates on the field. This data was used to build an immersive scene of the play.
