Abstract
A computer system may identify a first position of a physical camera corresponding to a first time period. The computer system may render a first virtual scene for the first time period. The system may project the first scene onto a display surface to determine a first rendered image for the first time period. The computer system may receive a first camera image of the display surface from the camera during the first time period. The system may determine a first corrected position of the camera by comparing the first rendered image to the first camera image. The system may predict a second position of the camera corresponding to a second time period. The computer system may render a second virtual scene for the second time period. The system may project the second virtual scene onto the display surface to determine a second rendered image for the second time period.
