Scripted stereo curves for stereoscopic computer animation

摘要

A computer-implemented method for determining a user-defined stereo effect for a computer-animated film sequence. A stereo-volume value for a timeline of the film sequence is obtained, wherein the stereo-volume value represents a percentage of parallax at the respective time entry. A stereo-shift value for the timeline is also obtained, wherein the stereo-shift value represents a distance across one of: an area associated with a sensor of a pair of stereoscopic cameras adapted to create the film sequence; and a screen adapted to depict a stereoscopic image of the computer-generated scene. A script-adjusted near-parallax value and a script-adjusted far-parallax value are calculated.

1. A computer-implemented method for determining a user-defined stereo effect for a computer-animated film sequence the computer-animated film sequence depicting a computer-generated scene, the method comprising:
obtaining a timeline of the film sequence, the timeline comprising a plurality of time entries; obtaining a stereo-volume value for at least two time entries of the plurality of time entries, wherein the stereo-volume value represents a percentage of parallax at the respective time entry; obtaining a stereo-shift value for the at least two time entries, wherein the stereo-shift value represents a distance across one of:
an area associated with a sensor of a pair of stereoscopic cameras adapted to capture a stereoscopic image of the computer-generated scene, anda screen adapted to depict the stereoscopic image of the computer-generated scene; obtain a near-parallax value and a far-parallax value for the at least two time entries; for the at least two time entries, calculate a script-adjusted near-parallax value based on the stereo-shift value and the product of the stereo-volume and the near-parallax value; for the at least two time entries, calculate a script-adjusted far-parallax value based on the stereo-shift value and the product of the stereo-volume and the far-parallax value; and storing, in a computer memory, the script-adjusted near-parallax value and script-adjusted far-parallax value.
