Normalization Of Vectors Associated With A Display Pixels Of Computer Generated Images

View page
US Patent:
53697375, Nov 29, 1994
Filed:
Aug 15, 1990
Appl. No.:
7/568529
Inventors:
Dariush Gholizadeh - Worcester MA
Hamid Assarpour - Harvard MA
Mohamed Messaoudene - Cambridge MA
Assignee:
Digital Equipment Corporation - Maynard MA
International Classification:
G06F 1562
G06F 1572
US Classification:
395126
Abstract:
A computer graphics method of and apparatus for normalizing vector-based terms for a plurality of display pixels associated with a polygon representing a surface of an object being imaged, the vector-based terms being determined from predetermined vectors at vertices of the polygon. The square (. eta. ) of the magnitude of a vector associated with each vector-based term is determined for each display pixel from the predetermined vectors at the vertices of the polygon. The quantity 1/. sqroot. eta. is approximated for each vector-based term using a series expansion employing. eta. , and each vector based term is multiplied by the corresponding approximation of 1/. sqroot. eta. to produce a normalized vector-based term for each display pixel.

Pen And Paper Information Recording System

US Patent:
56524129, Jul 29, 1997
Filed:
Jul 11, 1994
Appl. No.:
8/273396
Inventors:
Mohamed Lazzouni - Worcester MA
Ali Seyed Kazeroonian - Framingham MA
Dariush Gholizadeh - Framingham MA
Omar Ali - Roslindale MA
Assignee:
SIA Technology Corp. - Southboro MA
International Classification:
G08C 2100
US Classification:
178 18
Abstract:
An information recording system includes a writing paper having a writing surface and a prerecorded invisible pattern of pixels associated with the writing surface. Each of the pixels contains encoded, optically readable position information which identifies a coordinate position on the writing surface. The system further includes a pen having a tip and including an instrument for writing on the writing surface and a detector for detecting the position of the tip on the writing surface by optically reading the pixels and obtaining position information when the tip is in contact with the surface. The system further includes a recording unit coupled to the pen and responsive to the position information for electronically recording the position of the pen tip on the writing surface as the markings are made on the writing surface so that the recording unit contains an electronic representation of the markings on the writing surface.
