A disclosed gaming machine provides method and apparatus for presenting a plurality of game outcome presentations derived from one or more virtual 3-D gaming environments stored on the gaming machine. While a game of chance is being played on the gaming machine, two-dimensional images derived from a three-dimensional object in the 3-D gaming environment may be rendered to a display screen on the gaming machine in real-time as part of the game outcome presentation. To add excitement to the game, a 3-D position of the 3-D object and other features of the 3-D gaming environment may be controlled by a game player. Nearly an unlimited variety of virtual objects, such as slot reels, gaming machines and casinos, may be modeled in the 3-D gaming environment.

A system and process for generating, and then rendering and displaying, an interactive viewpoint video in which a user can watch a dynamic scene while manipulating (freezing, slowing down, or reversing) time and changing the viewpoint at will. In general, the interactive viewpoint video is generated using a small number of cameras to capture multiple video streams. A multi-view 3D reconstruction and matting technique is employed to create a layered representation of the video frames that enables both efficient compression and interactive playback of the captured dynamic scene, while at the same time allowing for real-time rendering.

A large depth of focus (DOF) display provides an image in which the apparent focus plane is adjusted to track an accommodation (focus) of a viewer's eye(s) to more effectively convey depth in the image. A device is employed to repeatedly determine accommodation as a viewer's gaze within the image changes. In response, an image that includes an apparent focus plane corresponding to the level of accommodation of the viewer is provided on the large DOF display. Objects that are not at the apparent focus plane are made to appear blurred. The images can be rendered in real-time, or can be pre-rendered and stored in an array. The dimensions of the array can each correspond to a different variable. The images can alternatively be provided by a computer controlled, adjustable focus video camera in real-time.

A system and process for rendering and displaying an interactive viewpoint video is presented in which a user can watch a dynamic scene while manipulating (freezing, slowing down, or reversing) time and changing the viewpoint at will. The ability to interactively control viewpoint while watching a video is an exciting new application for image-based rendering. Because any intermediate view can be synthesized at any time, with the potential for space-time manipulation, this type of video has been dubbed interactive viewpoint video.

A stand-alone or server-linked gaming terminal that displays on a plasma display in the top-box area a 3D-rendered mechanical device that is pre-rendered or rendered in real time using a 3D-graphics processor or the like. The 3D-rendered mechanical device depicts the game outcome or a bonus game displayed in the top box display. The images or animation representing the 3D-rendered mechanical device may be stored on a digital video recorder (DVR) within the gaming terminal or downloaded remotely from a storage device coupled to the gaming terminal. The DVR outputs the mechanical device images as analog video, and is capable of receiving analog video input, converting the analog video to a digital format such as MPEG, and storing the converted video on a storage media. Additional structural elements such as a frame may be arranged about the top-box display to add depth or dimensionality to the 3D-rendered images displayed thereon.

A three-dimensional real-time rendering engine can be driven by the playing and controlling module by the operator through various interactive methods, thus realizing the selectively instant playing of the virtual scene and the controlling of the virtual object. The system can be applied to virtual studios of television stations and other virtual interactive demonstrating occasions.

The present invention relates to a high precision method, model and apparatus for calibrating, determining the rotation of the lens scope around its symmetry axis, updating the projection model accordingly, and correcting the image radial distortion in real-time using parallel processing for best image quality.

The solution provided herein relies on a complete geometric calibration of optical devices, such as cameras commonly used in medicine and in industry in general, and subsequent rendering of perspective correct image in real-time. The calibration consists on the determination of the parameters of a suitable mapping function that assigns each pixel to the 3D direction of the corresponding incident light. The practical implementation of such solution is very straightforward, requiring the camera to capture only a single view of a readily available calibration target, that may be assembled inside a specially designed calibration apparatus, and a computer implemented processing pipeline that runs in real time using the parallel execution capabilities of the computational platform.

A method for progressively synchronizing stored copies of indexed media transmitted between nodes on a network. The method includes progressively transmitting available indexed media from a sending node to a receiving node with a packet size and packetization interval sufficient to enable the near real-time rendering of the indexed media, wherein the near real-time rendering of the indexed media provides a recipient with an experience of reviewing the transmitted media live. At the receiving node, the transmitted indexed media is progressively receive and any indexed media that is not already locally stored at the receiving node is noted. The receiving node further continually generates and transmits to the sending node requests as needed for the noted indexed media. In response, the sending node transmits the noted indexed media to the receiving node. Both the sending node and the receiving node store the indexed media. As a result, both the sending node and the receiving node each have synchronized copies of the indexed media.
