US Patent:

44255594, Jan 10, 1984

Filed:

Jun 2, 1980

Appl. No.:

6/155345

Inventors:

David L. Sherman - Sunnyvale CA

Assignee:

Atari, Inc. - Sunnyvale CA

International Classification:

G09G 116

US Classification:

340747

Abstract:

A method and apparatus utilizes information describing linear line segments in terms (1) the horizontal scan line scan at which the line segment originates, (2) the horizontal position within the line of the point of origin, (3) the direction of the line segment, and (4) the horizontal scan line at which the line segment terminates to generate line segment information on a raster-scan type video display. The line segments can be combined to form polygonal areas that are capable of movement and changes in size or shape on the display.

Filed:

Jan 5, 1981

Appl. No.:

6/222480

Inventors:

David L. Sherman - Sunnyvale CA

Assignee:

Atari, Inc. - Sunnyvale CA

International Classification:

G06F 314

US Classification:

340744

Abstract:

A method and apparatus provides for the generation of a number of elliptical images on a raster scan video display screen by storing information indicative of a predetermined model image, and for each elliptical image to be displayed, storing data indicative of the vertical and horizontal eccentricity of each image, and its display location. During display time, the vertical eccentricity, horizontal eccentricity, and display location binary information for each elliptical is accessed and used to sequentially read selected portions of the model image information to produce therefrom address signals indicative of the location of individual horizontal display elements that make up the desired elliptical image. The address signals are applied to a random access memory to store marker information indicative of the elliptical image at memory locations corresponding to the position on the display screen that the image will take. The random access memory is sequentially scanned in synchronism with the scan of the electron beam used to form the raster, converted to video information and displayed.

Filed:

Nov 15, 1991

Appl. No.:

7/794655

Inventors:

Samuel Lee - San Jose CA
David L. Sherman - Fremont CA

Assignee:

Shographics, Inc. - Mountain View CA

International Classification:

G06F 1562

US Classification:

395125

Abstract:

A mathematical computation circuit to interpolate attribute values along a line between two points where the attributes are known and a video circuit using the interpolation circuit. The interpolation circuit includes a circuit to calculate the rate of change of said attribute between said two points on a raster-scanned display on a per scan line basis and a circuit to add the rate of change of said attribute per scan line to the current attribute value for the current scan line as each new scan line occurs. The sum is used as the new current value. A video system uses multiple instances of this interpolation circuit and includes a sorter to sort vertices records from a display list and send the appropriate attribute data to the interpolation circuits. There rates of change are calculated and attribute values developed for each pixel location. A video control circuit then generates color, saturation and intensity data for use in filling a frame buffer in accordance with addresses generated by an address generation circuit.
