Patent number: 7127324Abstract: Provided are an information processing apparatus and a method, and in particular, an information processing apparatus and a method for employing a 3D model generated using 3D-CAD. When attribution information (a distance, an angle, the diameter of a hole, a dimensional tolerance, etc.) is added to a 3D model, as the amount of additional information is increased, it becomes difficult for the geometry of a 3D model and the attribution information to be seen on a display screen. The visual direction (the attribution allocation plane) is set for a generated 3D model, and attribution information is entered that is to be positioned on an attribution allocation plane. By designating the attribution allocation plane, the designated attribution information, together with the geometry of the 3D model, is displayed on the screen.Type: GrantFiled: February 19, 2002Date of Patent: October 24, 2006Assignee: Canon Kabushiki KaishaInventors: Yoshiyuki Batori, Ryozo Yanagisawa, Kazuma Shimizu, Yoshikazu Sasago, Masanari Morioka, Hiroshi Takarada

Patent number: 7119805Abstract: The present invention relates to information processing apparatus and methods and, more particularly, to information processing apparatus and methods making use of a 3D model (3D shape) prepared by 3D-CAD. For adding attribute information (distances, angles, hole diameters, dimensional tolerances, etc.) to the 3D model, it becomes harder to recognize the shape of the 3D model and the attribute information on a display screen with increase in the added information. Thus each visual axis direction (attribute arrangement plane) is set for the 3D model prepared and attribute information is inputted so as to be opposed to the attribute arrangement plane thus set. When the set attribute arrangement plane is then specified, the opposed attribute information, together with the shape of the 3D model set, is displayed on the display screen. Names of attribute arrangement planes are arranged so as to avoid overlap thereof on the display screen, thereby suppressing deterioration of visibility.Type: GrantFiled: February 14, 2002Date of Patent: October 10, 2006Assignee: Canon Kabushiki KaishaInventors: Yoshiyuki Batori, Ryozo Yanagisawa, Kazuma Shimizu, Yoshikazu Sasago, Masanari Morioka, Hiroshi Takarada
