Patent ID: 6992666

Claim:
A 3-dimensional model-processing apparatus capable of processing a 3-dimensional model appearing on a display unit comprising: a user controllable 3-dimensional sensor capable of generating information on a position and a posture of an appearance on the display unit; and a controller having a grasp-state-setting process of taking a relation between said sensor-generated information on a position and a posture of said 3-dimensional sensor and information on a position and a posture of said 3-dimensional model appearing on said display unit as a constraint relation on the basis of one of (a) a relation between a 3-dimensional position of said 3-dimensional model appearing on said display unit and the 3-dimensional position of a 3-dimensional tool appearing for said 3-dimensional sensor on said display unit and (b) a relation between a 3-dimensional posture of said 3-dimensional model appearing on said display unit and a 3-dimensional posture of said 3-dimensional tool appearing for said 3-dimensional sensor on said display unit, wherein said controller has a configuration for selecting a 3-dimensional model crossed by a straight optical beam generated in a specific direction by said tool appearing on said display unit and for carrying out said grasp-state-setting process on said selected 3-dimensional model.
