Abstract: A method of providing a monthly calendar view in a computer system uses either textual information or vertically stacked busy bars. If the textual information is utilized, the textual information includes a start time and a brief description of the event. The textual information is interactive allowing quick and easy additions or editing. If the vertically stacked busy bars are utilized, the bars may each represent a predetermined time frame. The presence of a bar indicates an event is scheduled during that time frame. Whichever method is utilized, an enlarged full text description of the event is directly selectable by placing an icon over the event and selecting the event.

Abstract: In a real-time texture mapping system, a more solid and naturally-mapped image is obtained with a minimum of computation volume. The texture-mapping system adds a texture image to an area of a polygon which forms a fundamental unit of three-dimensional image information of an object to be displayed on a screen. A geometry transfer engine (GTE) 61 extracts representing points from the polygonal area. Then, coordinates of the thus extracted representing points are subjected to the perspective transformation. Thereafter, the representing points, after the perspective transformation, are subjected to the linear interpolation in a graphic processing unit (GPU) 62 so that the image is formed.

Abstract: A method and apparatus for processing a character for anti-aliased display on a raster output device. A set of density values is computed for a set of raster positions to represent the character and the density values of the set are scaled to extend their range upward toward a maximum density value, whereby generally at least one of the density values of the set becomes the maximum density value. In one embodiment, the set of density values is computed from a rendering of the character at resolution higher than the resolution of the output device. In another embodiment, the character is created by a font having font metrics including a reference dimension, and the density values are scaled by computing adjusted values as a non-decreasing function of the original values, the function being defined to compute a maximum adjusted density value for at least one non-maximum density value.

Abstract: A sorting method is employed to draw data for polygons in a frame memory provided in a video game machine. The order in which the polygon data are to be drawn in the frame buffer memory is determined. For this, the polygon data are sorted. Data, for polygons, that include values on the first three-dimensional coordinates are divided into groups by employing distances between two points; from a predetermined point on the first three-dimensional coordinates to a point on the first three-dimensional coordinates in consonance with the coordinates of individual polygons Then, the order in which polygons are drawn in the frame buffer memory by employing the data for the polygons that belong to the individual groups is determined to be the order beginning with a group that has the largest or smallest distance between the two points. Through the above described procedures, the high speed sorting of the data for polygons is possible. At the same time, a memory area for the storage of data for polygons can be reduced.

The associated work is done in parallel with, or later than, an editing operation for the document. The editing operation interlocking work identifier refers to the correlating table. A process starting controller refers to an interlocking work starting process correlating table in which information about the associated works and starting processes are defined.

Abstract: A computer-based method for providing the generation of schemas for output documents. An output schema representing a desired output condition of a document is created from inputs comprising a tree transformation rule defined by at least a pattern, a contextual condition, an input schema, and user specified parameters.

Abstract: A method of and apparatus for preparing and modifying cross-tabulation analysis and reporting utilizes a data structure for storing aggregate data, gathered or input from a stream of data records. The data structure stores the aggregates of the data values, so that as cross-tab reports are generated, access to the original stream of data records is not necessary. Preferably, a tree-type data structure is utilized. The tree-type data structure is arranged relative to a root. The root of the tree is the first node in the tree. It has no parent node and no sibling nodes. Directly related to the root of the tree are labels of a first level. Labels of a second level and then labels of succeeding levels may follow, as required. Each level includes multiple nodes corresponding to the arrangement of the data. Each node has an array of accompanying cell in which the aggregates of the data values are stored.

Abstract: The effective display area of a window, in a window display apparatus, is corrected to prevent it from protruding beyond the visible area of the display. A coordinate data input device selects an icon and moves the icon to the display area to display a window image. Depending upon the location to which the icon is moved, correction of the resulting image may be necessary to ensure that the effective display area is shown. Once a window has been displayed, no correction is performed if the window is subsequently moved.

Abstract: Polygons defined in three-dimensional space are processed in order to facilitate subsequent manipulation. A first polygon is tested against a second polygon to identify a part of one of the polygons which may have a particular relationship. Thereafter, a second test is performed with reference to that polygon part. When producing rendering order lists, trees or directed graphs, a current favorite polygon (for placing on a list, tree or graph) is tested against a candidate polygon to determine whether the candidate polygon may be occluded by the favorite polygon. In performing this test a fragment of the favorite polygon may be identified which may occlude the candidate polygon and a fragment of the candidate polygon may be identified, as that which may be occluded by the current favorite. Thereafter, a second test is performed with reference to the fragment of the favorite polygon and the fragment of the candidate polygon.

Abstract: An improved graphical manipulation technique for a home communication terminal (HCT) includes a linked-list of commands controlling various video operations in an application specific integrated circuit (ASIC). After each command has been implemented by the ASIC, the ASIC proceeds to the next command without interrupting a host processor. Accordingly, the linked-list eliminates the need of the host processor to continually process interrupts at the completion of each instruction. The linked-list command structure aids in intensive video operations including bit block transfers, video capture, and video display.

Abstract: A system and method for generating three-dimensional (3D) color images with a simulated light sources. The operation of producing 3D images involves a complicated scheme of time consuming instructions issued by a controller to obtain 3D images. The present invention performs this result faster and more efficiently than conventional technology. The production of 3D color images according to the present invention is performed by a system. A controller manages the flow of data for the system. Control of the system generally occurs as follows: Signal characteristics representing light direction, view direction and a normal unit vector enter an input queue. The data is then written into a register file at assigned locations. After being written into the register file, light signals are pipelined into a floating point multiplier and accumulator (FMAC) for computation.
