摘要： Methods, systems, and computer readable media for shader lamps-based avatars of real and virtual people are disclosed. According to one method, shader lamps-based avatars of real and virtual objects are displayed on physical target objects. The method includes obtaining visual information of a source object and generating at least a first data set of pixels representing a texture image of the source object. At least one of a size, shape, position, and orientation of a 3D physical target object are determined. A set of coordinate data associated with various locations on the surface of the target object are also determined. The visual information is mapped to the physical target object. Mapping includes defining a relationship between the first and second sets of data, wherein each element of the first set is related to each element of the second set. The mapped visual information is displayed on the physical target object using a display module, such as one or more projectors located at various positions around the target object.

摘要： Methods, systems, and computer readable media for generating autostereo three-dimensional views of a scene for a plurality of viewpoints are disclosed. According to one system, a display is configured to display images from plural different viewpoints using a barrier located in front of the display, where the barrier has a pseudo-random arrangement of light ports through which images on the display are viewable. A renderer coupled to the display simultaneously renders images from the different viewpoints such that pixels that should appear differently from the different viewpoints are displayed in a predetermined manner. The pseudo-random arrangement of the light ports in the barrier smoothes interference between the different viewpoints as perceived by viewers located at the different viewpoints.

摘要： Methods, systems, and computer program products for imperceptibly embedding structured light patterns in projected color images for display on planar and non-planar surfaces are disclosed. According to one method, an image exposure period for detecting an embedded structured light patterns in a projected image is selected based on analysis of pixel polarities for different pixel intensities of a pixel color. Pixel intensities for the color are varied in the user image so that pixel polarities encode the structured light patterns during image exposure period. The user image is projected with the structured light patterns onto the surface. Depth information is continuously acquired and used to adjust display of the user image.
