Abstract: A rendering engine that supports directional focus navigation, in response to a directional input, shifts the focus to an appropriate focusable element. The rendering engine determines one or more focusable elements that are candidates to receive the focus based on the received directional input and based on the relative display locations of the focusable elements. The rendering engine selects the most appropriate candidate focusable element based on each candidate element's display location in relation to the display location of the element that currently has focus.

Abstract: There are provided an image generating system and program which can generate an image of an object variable in its state depending on an impacted position, in real-time with less amount of data and reduced load in computation. The image generating system generates an image of an aggregate object formed by a plurality of part objects. The image generating system comprises: an object determination section (120) which determines part objects within a predetermined area in the aggregate object as objects to be changed in display form when an impact is applied to the aggregate object and the impacted position is included within the predetermined area; and an image generation section (160) which changes at least one of shape, color, position, rotation angle, direction, moving direction and moving speed of the part objects determined as objects to be changed and generates an image. The aggregate object may be formed by assembling a plurality of part objects having different shapes without any gaps.

Abstract: A method and system for measuring an object represented by a three dimensional model includes an algorithm for displaying the three dimensional object in a 2 dimensional space. Once rendered in two dimensions, a user can identify two points on the object in that two dimensional space and in accordance with the invention, the system can determine the distance between the two points in the three dimensional space of the object. The system and method can use a pick function to determine the coordinates of each point in three dimensional space as a function of the two dimensional coordinates of each point selected in the two dimensional display space and determine the distance between the three dimensional coordinates of each point in the three dimensional space.

Abstract: The present invention is directed to a two-handed input control system that dynamically changes an input-to-object mapping for mapping movement of a graphical object on a display of a virtual scene as the viewpoint of the virtual scene changes. As input to the system for changing the position of the graphical object occurs, the mapping is revised to reflect changes in the viewpoint so that the object moves as inherently expected. That is, changes to the viewpoint change the mapping so that a correspondence between the viewpoint and the input space is always maintained. During movement of the object a screen cursor is visually suppressed so that the movement of the graphical object and the screen cursor do not split the attention of the user. The screen cursor is always maintained within the visual display region of the virtual scene even when the object moves out of the visual display region by moving the cursor to a center of the screen when it reaches an edge of the screen.

Abstract: One or more embodiments of the invention provide a method, apparatus, and article of manufacture for positioning a graphical component in a computer-implemented drawing program. A selection of a graphical component displayed on a display device is received. Thereafter, a first feature of the graphical component is inferred. The display of the graphical component is moved (e.g., by a user using a cursor control device). Underlying geometry is then analyzed to determine one or more second features of the underlying geometry that can mate with the first feature. Feedback is then displayed that indicates placement potential for the graphical component based on the first feature mating with one of the second features.

Abstract: The invention relates to a method of analyzing an object data set comprising points in a multi-dimensional space, in which dataset a tubular structure, such as blood vessels, occurs. The method comprises the following steps: a) choosing a screen position related to the tubular structure; b) determining the multi-dimensional co-ordinates of a starting position associated with said screen position; c) deriving a plane through said starting position having its normal directed to the tubular structure; d) determining a surface point of the tubular structure as a target position associated with the starting position; e) selecting a number of points forming part of the surface of the tubular structure in the vicinity of the target position; f) determining the surface point in the selection which is closest to the plane; and g) using the surface point determined in the step f) as a new starting position. This method allows accurate and reproducible selection of the starting position.

Abstract: An image display device includes a smoothing unit that filters the image data to be displayed. According to one aspect of the invention, only bright parts of the image that are adjacent to dark parts are smoothed, thereby improving the sharpness of dark dots and lines displayed on a bright background. According to another aspect, different primary colors are smoothed with different characteristics, enabling unwanted colored tinges to be removed from the edges of white areas. According to still another aspect, smoothing moves the luminance centroids of all primary colors in a direction in which the display screen is scanned, to reduce ringing effects without needless loss of edge sharpness.

Abstract: Embodiments of the present invention efficiently support rendering of high resolution images under zone rendering. In particular, a bin array rectangle and binner clipping rectangle for determining primitive-zone intersections. Both of these rectangles are defined by graphics device state variables containing the screen-space location of the rectangle corners. In particular, the binner clipping rectangle is used to define the visible region in screen coordinates. Objects completely outside the binner clipping rectangle in one or more directions will be discarded. Objects that cannot be trivially rejected are subjected to bin determination. The bin array rectangle handles color buffer resolutions larger than could otherwise be accommodated by the optimally-renderer image limits.

Abstract: The present invention provides a computer system with an improved graphically-oriented user interface that permits the user to more easily select for manipulation one object from a number of objects that overlap or are in close proximity to one another at a common location in a graphic display. In a preferred embodiment, the invention presents the computer user with the opportunity to preview all possible objects that the cursor might be identifying at its current position and the ability to select one of those objects for manipulation. Thus, rather than cycling through the entire list of objects available for selection at a location in the display, the user can immediately narrow the list down to the desired selection only. The present invention prevents selection errors and drastically reduces the number of user inputs required to select an object.

Abstract: A three-dimensional graphic having a specific positional relationship with a predetermined point in an image made up of a three-dimensional graphic is detected. The image controller adds index information for identification to a plurality of three-dimensional graphics. The drawing device forms two-dimensional projected images by projecting the plurality of three-dimensional graphics onto predetermined planes. The two-dimensional projected images are assigned the index information corresponding to the index information assigned to the relevant three-dimensional graphics. When the projecting point(s) of a predetermined point in the image exist in the two-dimensional projected images, the graphics detector detects index information assigned to the two-dimensional projected images and detects the three-dimensional graphics assigned the index information corresponding to the detected index information.

Abstract: To select a graphic primitive hidden behind a graphic primitive displayed in foreground, a point on the display screen is pointed to by a pointing device. A CPU detects graphic primitives that include the specified point based on the position and the size indicated by the graphic primitive information stored in the system memory and further detects the smallest graphic primitive completely included in one or more graphic primitives among the detected graphic primitives. The detected smallest graphic primitive is thereafter processed as the selected graphic primitive.
