PROBLEM TO BE SOLVED: To reduce a load of a calculation process by correcting a value of a component of a coordinate value in a three dimensional coordinate system to one of previously specified values. SOLUTION: An information processing apparatus includes: a determining unit 32 for determining whether a line segment which is parallel to an axis of the thee dimensional coordinate system and includes a point specified by a coordinate value after being converted to the three dimensional coordinate system exists or not on a plane of a three dimensional shape based on shape data; and a correction processing unit 33 for correcting a coordinate value after conversion into the other coordinate value existing on the line segment when the line segment is determined as existing by the determining unit 32. The other coordinate value is a coordinate value to be one of values which are previously specified so that values of an axis component are arranged on the axis with a predetermined interval, and is a coordinate value where difference between the value of the axis component and a value of the axis component among converted coordinate values is not larger than a predetermined value.
