US Patent:

7039505, May 2, 2006

Filed:

Jul 18, 2003

Appl. No.:

10/622382

Inventors:

David A. Southard - Bedford MA, US
Lowell F. Bell - Boston MA, US
Michael A. Aucoin - North Andover MA, US
Frédéric Gouin - Concord MA, US

Assignee:

Avidyne Corporation - Lincoln MA

International Classification:

G01C 23/00

US Classification:

701 3, 701200, 701202, 340945, 340971, 342 26 A

Abstract:

A method for creating minimal data representing a source image is presented. The source image is divided into a grid of cells. A color is selected for each cell corner based on sampling an area defined by the cell corner. An indication of the selected color is stored in an array dependent on the co-ordinates of the cell corner in the source image.

International Classification:

G06T 1300

US Classification:

345474, 700 61

Abstract:

A hierarchical 3D graphics model can be viewed as a hierarchical graph of its nodes and their associated motions, with the mathematical type of motions graphically indicated. A user can click on a displayed motion to edit it. A motion API provides one or more of the following features: (1) spatial predicate functions; (2) functions for scaling motion intensity; (3) classes for shake, spin, and swing motions; (4) motion classes with a GUI interfaced for defining their duty cycle; (5) functions for defining and computing 0 through 2 order derivatives of 3D position and orientation as function of time; (6) behaviors that constrain motions by boundaries in which the constraint is a reflection, clamp, andor onto constraint, or in which the boundary is a composite boundary. Motions can be defined by successive calls to an API and then be saved in a file.
