摘要： A method and system for rendering bicubic surfaces whereby at least a portion of the bicubic surfaces are defined by sixteen control points and bounded by four boundary curves, and each boundary curve is formed by boundary box of line segments formed between four of the control points. The method and system of include transforming only the control points of the surface given a view of the object, rather than points across the entire bicubic surface. Next, a pair of orthogonal boundary curves to process is selected. After the boundary curves have been selected, each of the curves is iteratively subdivided, wherein two new curves are generated with each subdivision. The subdivision of each of the curves is terminated when the curves satisfy a flatness threshold expressed in screen coordinates, whereby the number of computations required to render the object is minimized.

摘要： A communication system including a transmitter, a receiver, and a serial link, in which encoded data (e.g., video, audio, and optionally also other auxiliary data) are transmitted from the transmitter to the receiver. The serial link can but need not be a TMDS or TMDS-like link. In typical embodiments, packets of encoded audio data are transmitted over each of one or more channels of the link during data islands between bursts of encoded video data, a pixel clock is transmitted over the link, and the receiver regenerates a clock for the audio data using time code data in the packets and the pixel clock. Other aspects of the invention are transmitters for transmitting encoded data and a pixel clock over a serial link, receivers for receiving such data and pixel clock and performing audio clock regeneration, and methods for transmitting encoded data and a pixel clock over a serial link and performing clock regeneration using the transmitted data and pixel clock.

摘要： A graphics rendering system creates an image based on objects constructed of polygonal primitives, which can generate the perception of three-dimensional objects displayed on a two-dimensional display device. An anti-aliasing operation is applied to silhouette edges of the objects, which are the edges of primitives which are displayed at the perimeter of an object. A silhouette edge can be identified by determining how many times an edge is rendered, with each instance of the rendering of an edge corresponding to the rendering of a primitive that adjoins the edge. An edge that is rendered exactly once is interpreted as a silhouette edge. An example of a silhouette edge is an edge that adjoins one triangular primitive that is viewable and another triangular primitive that is hidden from view by other primitives. Another technique for identifying a silhouette edge can be applied to closed objects by determining whether a first primitive adjoining an edge is hidden from view by other primitives and a second primitive also adjoining the edge is viewable. Once the silhouette edges are identified, the anti-aliasing operation is applied thereto.

摘要： A method and system for simulating motion of a polygon on a display screen. The polygon may be included in a set of polygons used to model a three-dimensional object. The position of the polygon is defined by vertices tracked in a subpixel coordinate system existing in a computer-readable medium. The subpixel coordinates of the vertices are used to identify the pixels on the display screen having coordinates that correspond to subpixel coordinates lying within or, optionally, at the boundary of the polygon. The identified pixels are those that are to be lighted on the display screen to generate the image of the polygon. The display properties of the lighted pixels are selected by interpolation based on defined pixel display parameters assigned to the vertices of the triangle. As motion of the polygon is tracked in the subpixel coordinate system, the corresponding display on the display screen is repeatedly adjusted. The method of identifying and interpolating the display parameters of the pixels using the subpixel coordinate system provides the appearance of smooth polygon motion.

摘要： A graphics rendering system creates an image based on objects constructed of polygonal primitives. Aliasing effects in the image are reduced by applying an anti-aliasing scheme to the areas of the image representing silhouette edges of the objects. The silhouette edges are anti-aliased by creating anti-aliasing primitives which vary in opacity. These anti-aliasing primitives are joined to the silhouetted edges, and create a region in the image where the objects appear to blend into the background.

摘要： A method and apparatus for drawing at least a one pixel wide antialiased line on an edge of a filled polygon. The apparatus comprises an interpolator, having a set up unit and an iterator unit, and a blender. The set up unit determines various parameters of the line to be drawn and selects a pair of pixels adjacent to and straddling an idealized line representing the line to be drawn, where the first pixel is claimed by the edge of the polygon as a filled pixel. The iterator unit determines the coverages of the second pixel based on the parameters output by the set up unit. The blender determines the color intensity value of the second pixel as a function of its coverage and writes the color value into a memory. The apparatus also incorporates methods for antialiasing polygon meshes and resolving accumulation error in the derivation of each pixel's position.

摘要： A method and apparatus for anti-aliasing vectors, arcs and circles comprising a plurality of pixels on a video display. The distance, d, of each pixel from the centerline of a curve is computed using a plurality of linearly dependent equations. The intensity of each pixel is set as a function of the magnitude of the distance, d, of the pixel from the centerline of the curve. In some cases, the distance, d, is compared with ranges of distances and the intensity of the pixel set according to the range within which the pixel is located. In other cases, the intensity of the pixel is simply inversely proportional to its distance, d, from the centerline.
