The GUI also employs active, persistent and slider variables to probe variable relationships, group relationships and dataset relationships.

An automated method of rapidly producing customized 3D graphics images in which various user images and video are merged into 3D computer graphics scenes, producing hybrid images that appear to have been created by a computationally intensive 3D rendering process, but which in fact have been created by a much less computationally intensive series of 2D image operations. To do this, a 3D graphics computer model is rendered into a 3D graphics image using a customized renderer designed to automatically report on some of the renderer's intermediate rendering operations, and store this intermediate data in the form of metafilm. User images and video may then be automatically combined with the metafilm, producing a 3D rendered quality final image with orders of magnitude fewer computing operations. The process can be used to inexpensively introduce user content into sophisticated images and videos suitable for many internet, advertising, cell phone, and other applications.

A computer system which includes a central processing unit, a bus, and a memory store coupled to the central processing unit that includes a psuedo 3D rendering mechanism. Typically, the rendering mechanism is loaded in the memory store, but can be implemented in an application's specific integrated circuit further coupled to the central processing unit via the bus. The psuedo 3D rendering mechanism is used to generate a psuedo 3D rendered virtual image using only two dimensional prerendered selected views of 3D objects to be displayed. As the viewing orientation shifts from point to point, an adequate three-dimensional rendering is provided based on these selected views. These selected views are designed for display on a display device further connected to the computer system.

A 3D rendering method is proposed to increase the performance when projecting and compositing multiple images or video sequences from real-world cameras on top of a precise 3D model of the real world. Unlike previous methods that relied on shadow-mapping and that were limited in performance due to the need to re-render the complex scene multiple times per frame, the proposed method uses, for each camera, one Camera Projection Mesh (“CPM”) of fixed and limited complexity per camera. The CPM that surrounds each camera is effectively molded over the surrounding 3D world surfaces or areas visible from the video camera. Rendering and compositing of the CPMs may be entirely performed on the Graphic Processing Unit (“GPU”) using custom shaders for optimal performance. The method also enables improved view-shed analysis and fast visualization of the coverage of multiple cameras.

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 3D rendering texture caching scheme that minimizes external bandwidth requirements for texture and increases the rate at which textured pixels are available. The texture caching scheme efficiently pre-fetches data at the main memory access granularity and stores it in cache memory. The data in the main memory and texture cache memory is organized in a manner to achieve large reuse of texels with a minimum of cache memory to minimize cache misses. The texture main memory stores a two dimensional array of texels, each texel having an address and one of N identifiers. The texture cache memory has addresses partitioned into N banks, each bank containing texels transferred from the main memory that have the corresponding identifier. A cache controller determines which texels need to be transferred from the texture main memory to the texture cache memory and which texels are currently in the cache using a least most recently used algorithm. By labeling the texture map blocks (double quad words), a partitioning scheme is developed which allow the cache controller structure to be very modular and easily realized. The texture cache arbiter is used for scheduling and controlling the actual transfer of texels from the texture main memory into the texture cache memory and controlling the outputting of texels for each pixel to an interpolating filter from the cache memory.

A server process renders instances of a 3D virtual environment as video streams that may then be viewed on devices not sufficiently powerful to implement the rendering process natively or which do not have native rendering software installed. The server process is broken down into two steps: 3D rendering and video encoding. The 3D rendering step uses knowledge of the codec, target video frame rate, size, and bit rate from the video encoding step to render a version of the virtual environment at the correct frame rate, in the correct size, color space, and with the correct level of detail, so that the rendered virtual environment is optimized for encoding by the video encoding step. Likewise, the video encoding step uses knowledge of motion from the 3D rendering step in connection with motion estimation, macroblock size estimation, and frame type selection, to reduce the complexity of the video encoding process.
