Abstract
Techniques are disclosed for rendering an anamorphic projection of 3D scene geometry on a handled device using a correct asymmetric perspective geometry projection. Once pose of the handheld device is determined, a relative eye position may be inferred when the device is tilted away from an initial or default pose, based on data supplied by accelerometers. Thus, embodiments of the invention result in a holographic style display without the need for glasses or external sensing attachments.
