Interactive three dimensional displays on handheld devices

摘要

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.

主权项

1. A computer-implemented method for rendering a set of three-dimensional (3D) geometry on a display of a handheld device, the method comprising:
determining, based on accelerometer data, a current pose of a handheld device; determining, based on a current ambient lighting state, a lighting response to apply in rendering the 3D geometry on the display; and in response to the current pose of the handheld device and the current ambient lighting state, rendering an anamorphic 3D image of the 3D geometry on the display of the handheld device, wherein the anamorphic 3D image presents a holographic style image on the display of the handheld device when viewed from a relative eye position corresponding to the current pose, lighted based on the current ambient lighting state; wherein the holographic style image creates an illusion of at least a portion of the 3D geometry appearing in 3D space above or below the plane of the display of the handheld device by distorting the 3D geometry using an anamorphic projection.
