Three dimensional coordinate location device, method for same, and program

摘要

There is provided a 3-dimensional coordinate specifying device which can accurately specify a set or sets of optional coordinates in a 3-dimensional space by a simple manipulation. The 3-dimensional coordinate specifying device includes a standard plane setting section 22 for setting an optional standard flat plane 31 in a 3-dimensional space, a standard point determining section 23 for determining values of coordinates of an optional point on the set standard flat plane 31, a light beam emitting section 25 for emitting an imaginary light beam 33 at an optional angle from the determined standard point 32, a point specifying section 26 for specifying an optional point on the emitted imaginary light beam, and a coordinate calculating section 27 for calculating 3-dimensional coordinates of the specified point.

主权项

1. A 3-dimensional coordinate specifying device characterized by the fact that said device comprises:
a standard plane setter configured to set at least one optional standard flat plane, wherein when a displaying object displayed in a 3-dimensional space having an XYZ coordinate system has a flat plane, which is not parallel to any of an XY plane, a YZ plane and a ZX plane of the XYZ coordinate system, the standard flat plane is parallel to the flat plane, while when the displaying object has no flat plane, the standard flat plane is perpendicular or parallel to a coordinate plane; a standard point determiner configured to determine an optional point on the standard flat plane, set by said standard plane setter, as a standard point; a light beam emitter configured to emit an imaginary light beam at an optional angle from the standard point determined by said standard point determiner; a point specifier configured to specify an optional point on the imaginary light beam emitted by said light beam emitter; and a coordinate calculator configured to calculate 3-dimensional coordinates of the point specified by said point specifier.
