Abstract: An array of view-dependent sprited tiles provide different views of an image texture (e.g., structure, color, shading, illumination, transparency, as well as other image attributes). The different views of the image texture correspond to different viewing angles at which a user would see the tiles when they are applied to an image geometry. In one implementation, the view dependent sprited tiles are two-dimensional projections of three-dimensional structures. The projections maintain the dimensions (including shape) of the front surfaces of three-dimensional structures at different viewing angles. A projection that meets these characteristics is the oblique parallel projection.

Abstract: Data corresponding to one or more data dimensions is obtained from a data source. A smart radar chart graphical user interface is generated. The smart radar chart graphical user interface includes a visual representation of the obtained data corresponding to the one or more data dimensions. Each data dimension is displayed radiating from a central point, and data corresponding to a data dimension is displayed at a position indicating the value of the data in relation to a reference value so as to enable the identification of an exception.

Abstract: Techniques are described for selecting and displaying specific content elements from within content of a media asset, such that the content elements may be displayed within a reserved portion of a user display, thereby providing a visual summary of the media asset content. The content elements may be provided along with a graphical representation of the content elements indicating, for example, their importance within the media asset relative to one another and/or to a user preference. In this way, the user may quickly and easily assess his or her level of interest in the media asset.

Abstract: A drag-and-drop user interface (DDUI) can generate multiple charts in an integrated chart report and supports the drag-and-drop method of adding fields to the integrated chart report. When a field is dropped from a field list into a multiple chart drop zone, the DDUI will automatically generate additional charts to represent the data in the dropped field. An additional chart will be generated for each unique entry in a data field. The number of charts can be modified by selecting particular elements in the dropped field, by means of a drop-down menu. The drop-down menu enables the elimination or addition of elements of the dropped field. Each additional field dropped into the multiple chart drop zone will add a chart to the chart report. Conversely, each field dragged out of the multiple chart drop zone will eliminate a chart from the chart report. The DDUI can accommodate various chart types.

Abstract: An apparatus, method, and medium for controlling image orientation are disclosed. An orientation mode detector measures multi-directional rotational angles of a display panel and determines an orientation mode for original image data based on the measured rotational angles. A system memory stores orientation parameters corresponding to a plurality of image orientation modes. A system controller initially acquires information indicating the orientation mode from the orientation mode detector, and it extracts orientation parameters corresponding to the acquired information from the system memory. Finally, a driver changes an orientation of the original image data according to the extracted orientation parameters.

Abstract: A printer driver generates output data adapted to the processing power of a printer. When the printer driver receives a draw command from an operating system, a complexity value of the draw command is calculated depending on the type of the command and/or the number of contour points of a clipping area included as a parameter of the command. A processing mode is selected depending on the complexity relative to first and second threshold values. In a first processing mode, a draw command to draw image data and a clip command are simply output. In a second processing mode, a draw command to draw image elements generated in accordance with a clip command is output. In a third processing mode, mask data is generated from a clip command, and a command to calculate the logical AND between image data and the mask data is output.

Abstract: A computer graphics accelerator apparatus and method determines whether a pixel at predetermined pixel co-ordinates in an area being rasterized is within a triangle defining a sub-area of the area. The coordinate system in relation to which the triangle is defined is translated such that the pixel co-ordinates are disposed at the origin of the coordinate system. Determinants of matrices based on at least two of the coordinate values of at least two of the vertices are calculated and their signs compared. Based on this comparison a determination as to pixel location with respect to the triangle may be made.

Abstract: Method for controlling stroke video generation components by creating a program to command the video generation components to provide video signals and integrating high level software constructs into the program.

Abstract: Accurate drawing without position displacement is performed irrespective of different aspect ratios on the transmission side of drawing information and on the reception side. In a drawing apparatus 50, a normalized coordinate transformation section 62 transforms normalized coordinates (x3, y3) transmitted via a network into rear coordinates (x2, y3) in accordance with an inverse function g1?1 of a function g1 for normalizing an aspect ratio of an image displayed on a display, and a rear coordinate transformation section 63 transforms the rear coordinates (x2, y2) into front coordinates (x1, y1) in accordance with an inverse function f1?1 of a function f1 corresponding to the aspect ratio of the image. A drawing section 67 draws an image on the screen of the display in accordance with the front coordinates (x1, y1). The invention is applicable, for example, to an application sharing drawing information.

Abstract: When a Bézier spline is fitted to a plurality of points the two tangent handles at each control point can be very different in length. A method of fitting a second spline to the first spline that has tangent handles of equal length at each control point is provided. A point is found on the first spline that is close to the midpoint between the two control points defining the tangent handles. This point is a new control point on the second spline. Tangent handles to the new control point are then found such that they have a slope equal to the tangent to the first spline at the new control point, the sum of their lengths is equal to the sum of the original two tangent handles and their lengths are equal to each other. A second spline found in this way closely approximates the first spline. The lengths of the tangent handles may be adjusted to provide a better fit.
