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.
