A GUI is disclosed including a set of visualization routines designed to improve display, visualization and manipulation of multi-dimensional data. Many of the routines combine 2D and 3D renderings with domain selecting criteria and stacking criteria with line segments connecting variable values between records in a given dataset or between corresponding variable values in records of related datasets. 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 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.

An object-oriented design program provides is configured to instantly render in a three-dimensional interface user CAD designs received as CAD-based design elements (e.g., CAD blocks or lines). The object-oriented program renders the user CAD designs regardless of whether the user designs are practical, or use finishes or colors that are in-stock for the selected design elements. In addition, the object-oriented program can also create intelligent software objects for the CAD-based elements at a later time, upon request by the user. The intelligent software objects can be configured to automatically resolve themselves in view of one or more system limitations and rules in related components, and to replicate any such resolution back to the CAD-based blocks if desired. Thus, a user can have the benefits of instant 3D rendering of CAD drawings with or without the automatic resolution provided by intelligent software objects, depending on the situation.

Systems and methods for repeat photography and difference extraction that help users take pictures from the same position and camera angle as earlier photos. The system automatically extracts differences between the photos. Camera poses are estimated and then indicators are rendered to show the desired camera angle, which guide the user to the same camera angle for repeat photography. Using 3D rendering techniques, photos are virtually projected onto a 3D model to adjust them and improve the match between the photos, and the difference between the two photos are detected and highlighted. Highlighting the detected differences helps users to notice the differences.

A device for generating a 3D image based on 2D graphical content of an image and depth information (i.e., Z-map) to be displayed on a display includes an application processor, a graphical processing unit (GPU), a 3D rendering unit and a display. The application processor is capable of sending 2D graphical content to the GPU, which is stored in memory. The GPU also includes a depth table having predefined depth information corresponding to the 2D graphical content. The GPU includes a depth module which monitors or identifies the 2D graphical content and requests a graphics library to paint a corresponding area in the Z-map that has the same size and position in the Z-map as that of the 2D graphical content. The GPU sends the 2D graphical content and the painted Z-map to a 3D rendering unit which creates a 3D image to be shown on a display.

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.

In one embodiment, an ultrasound system is provided that includes a probe having a 2D array of transducers for acquiring ultrasound information along a plurality of scan lines through an object in real time. The scan lines are arranged to define volumetric data corresponding to a volume of interest (VOI) in a subject or patient. One such VOI may include the human heart or some portion of the human heart. The system includes a beamformer configured with scan parameter values that define the scan lines. An image buffer stores multiple data volumes acquired over time that are successively retrieved and processed by a display processor. The display processor accesses the data volumes stored in the image buffer successively to control generation of at least one of 2D and 3D renderings based on display parameters, wherein the display processor obtains from the image buffer a first data volume defined based on first scan parameter values, while the probe acquires ultrasound information for a second data volume that is entered into the image buffer. The second data volume is defined based on second scan parameter values. A navigation view presents in real time the renderings generated by the display processor with their corresponding 3D orientation. A navigator is provided that controls the display of the navigation view in real time such that, as the user adjusts a display parameter value to change a view plane, images presented in the navigation view are updated to reflect the view plane. A user interface is provided for adjusting the scan and display parameter values.
