PROBLEM TO BE SOLVED: To search an object at high speed which is blocked by another object when seen from a certain viewpoint in a space.SOLUTION: An object search device includes: a database; a rendering unit; a calculation unit; and an object search unit. The database stores arrangement information of a plurality of objects in a space. The rendering unit draws the plurality of objects from a viewpoint set in the space. The calculation unit performs drawing by using the rendering unit and calculates the number of objects in which at least one part of an image is hidden by an image of another object. The object search unit executes search calculation in which the object is searched in which at least one part is blocked by another object when seen from the viewpoint in the space with the number calculated by the calculation unit being the upper limit of the search result number, based on the database. |
