Abstract: A method of generating a composite image includes capturing a video image of a physical scene with a camera, identifying a green-screen region within the video image, identifying a viewpoint and a position and/or orientation of the green-screen region relative to the viewpoint, and generating a modified video image rendered from the viewpoint onto a display surface in which the green-screen region is replaced with an image of a virtual object. The image of the virtual object is generated by projection rendering of a model of the virtual object based on the position and/or orientation of the green-screen region relative to the viewpoint such that the virtual object is constrained within the green-screen region.

Abstract: A system, method or compute program product for restricting convergence and divergence when viewing stereo 3D imagery. The technique includes receiving data representing a 3D virtual scene, receiving data indicating an eyepoint and a three-dimensional frustum rendering region with the three dimensional frustum rendering region identifying a position and orientation of a render plane, receiving data indicating a user stereo comfort region, rendering virtual objects in a first portion of the 3D virtual scene that is in the three-dimensional frustum rendering region and within the user stereo comfort region onto the render plane according to a first type of projection, and rendering virtual objects in a second portion of the 3D virtual scene that is in the three-dimensional frustum rendering region and outside the user stereo comfort region onto the render plane according to a different second type of projection.
