INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND COMPUTER PROGRAM PRODUCT

An information processing apparatus (10) for generating a toolpath of a three-dimensional fabrication apparatus (20) includes circuitry (101) to slice three-dimensional data of a three-dimensional object into a plurality of parallel planes to generate a first image slice and a second image slice, extract a first contour in the first image slice and a second contour in the second image slice, the first contour dividing the first image slice into an area inside the three-dimensional object and an area outside the three-dimensional object, the second contour dividing the second image slice into the area inside the three-dimensional object and the area outside the three-dimensional object, correct a third contour of a third image slice disposed between the first image slice and the second image slice based on the first contour of the fist image slice and the second contour of the second image slice, and create a toolpath from the first contour, the second contour, and the third contour.
