ABSTRACT:
A three-dimensional graphic apparatus generates a three-dimensional image using computer graphics, in which the positional relationship between matters, such as furniture in a three-dimensional image, can be changed readily and accurately. A moving object indication unit indicates one of the matters in the three-dimensional image as an object matter. A search direction indication unit indicates a search direction of a base polygon constituting a base matter coming into contact with the object matter, from a notice point of a line of sight. A base polygon search unit selects, from among polygons located on a straight line extending from the notice point in the search direction, a polygon closest to the notice point as the base polygon. An object polygon selection unit selects an object polygon, which is a polygon to be brought into contact, from among polygons constituting the object matter. A neighboring unit rotates the object matter so that the object polygon will be parallel to the base polygon and moves the object matter so that the object polygon will be parallel to the base polygon and moves the object matter so that the object polygon and the base polygon lie on the same plane.
