Patent number: 10803629Abstract: The embodiments discussed herein involve flood filling a region with anti-aliasing. In forming a fill region, a candidate pixel can be included in the region based on a color of the pixel and also a color of a neighbor of the point. The inclusion basis may be a color distance between a seed color and the points, and a color distance between the seed color and the point's neighbor. Points in the region may be weighted according to their color distance relative to the seed color, where the color distance can also take into account alpha values. Flood filling may be anti-aliased by assigning alpha values to pixels in gaps between corners of the fill region, where an alpha value may be proportional to a point's contribution to the gap. Dimples in a fill region may be tested for and used to determine which of two flood fill algorithms to use.Type: GrantFiled: October 6, 2015Date of Patent: October 13, 2020Assignee: AUTODESK, INC.Inventors: Ian R.

Patent number: 7159955Abstract: This invention relates to an endless traction band that is used to propel band laying vehicles [i.e., vehicles which use endless traction bands rather than tires to contact the terrain over which they are driven, e.g., tractors, tanks, bulldozers, etc.]. A novel sprocket wheel having a plurality of radially extending and offset teeth cooperates with an endless traction band having a plurality of holes. Longitudinally consecutive holes define either meshing areas or clip areas. The meshing areas are adapted to be engaged by the sprocket wheel and the clip areas are adapted to support clips.Type: GrantFiled: December 16, 2003Date of Patent: January 9, 2007Assignee: Soucy International Inc.Inventors: Yves St-Pierre, Hugo Bastien, Eric Blais, Chad Olson

Patent number: 6840588Abstract: This invention relates to an endless traction band that is used to propel snowmobiles and more particularly, to an improved ground-engaging side of the traction band, which helps reduce the noise and vibration levels during the operation of the snowmobile. The various protruding lug configurations defines a predetermined number of different lug profiles, from which the sequence of profiles on the endless band are generated in such a way so that every sequence of profiles is different from one another.Type: GrantFiled: October 25, 2002Date of Patent: January 11, 2005Assignee: Soucy International Inc.Inventors: André Deland, Yves St-Pierre, Éric Blais
