Abstract: Disclosed are motion effect generation apparatuses and a computer-readable recording medium for program codes for implementing the motion effect generation apparatuses. The apparatus for generating a motion effect may comprise a segment generation part configured to divide a moving path of a camera or an object obtained from raw motion information into a plurality of segments; a scaling part configured to adjust a size of each of the plurality of segments according to a driving range of a motion apparatus; and a merging part configured to generate a motion path of the motion apparatus by merging the plurality of segments sizes of which are adjusted. Therefore, time and costs for producing 4D movies to which motion effects are applied can be reduced. In addition, they can be easily applied to 4D movie theaters, 4D rides, home theater equipment, and home game machines.
