A controller includes a memory that stores image data in a vector format representing a shape in the vector format, a contour extractor that extracts a contour of the shape based on the image data in the vector format, a reduced-size contour generator that generates reduced-size contours inside the contour by sequentially reducing inwardly the contour extracted by the contour extractor, and a moving controller that controls a carriage moving mechanism such that a foil transfer tool moves along the reduced-size contours and the contour in order from an innermost reduced-size contour to the contour at an outermost side.

A sliced model generating apparatus includes a storage, a generator, an information adder, a converter, an area setter, and a color adder. The storage stores a three-dimensional model that includes attribute information including at least color information. The generator generates a contour polyline including a plurality of line segments. The information adder associates the line segments with the attribute information of the three-dimensional model. The converter converts the contour polyline whose line segments are associated with the attribute information into an image coordinate system. The area setter sets, in a region surrounded by the contour polyline converted into the image coordinate system, each of areas targeted for coloring adjacent to a corresponding one of the line segments. The color adder colors each of the areas targeted for coloring with a color based on the attribute information associated with a corresponding one of the line segments, thus generating a sliced model.

A three-dimensional printing apparatus includes a projector to project a first image onto a tank and a controller to control the projector. The controller includes an acquirer, an inclination calculator, a vertical and horizontal correction value calculator, a memory, and a corrector. The acquirer projectively transforms the first image, thus acquiring a second image obtained by correction of the first image. The second image includes a projection sub-image. The inclination calculator calculates horizontal and vertical inclinations of the projection sub-image in the second image. The vertical and horizontal correction value calculator calculates a first correction value based on the horizontal inclination, and calculates a second correction value based on the vertical inclination. The memory stores a third correction value. The corrector corrects the brightness distribution of the second image using a fourth correction value calculated based on the first to third correction values.

A projection system generates a pre-projective transformation image based on an extracted image obtained from a source image, applies projective transformation to the pre-projective transformation image using the parameters to produce an output image, and causes the projector assembly to output the output image and project a projected image on a surface for projection. If the extracted image has been obtained in a predetermined range of the source image, the projected image is projected onto the surface for projection so that an origin of the pre-projective transformation image is located at a predetermined position in the surface for projection. When, a change, from the predetermined range, of a range to extract in the source image to obtain the extracted image leads to a change of a coordinate of pixels of the pre-projective transformation image by a V pixel unit from a coordinate obtained when the extracted image has been obtained in the predetermined range, the output image is produced by translating the pre-projective transformation image by a V pixel and applying projective transformation to the pre-projective transformation image using the parameters.

A three-dimensional printing apparatus includes a controller to control first and second projectors that apply equal or substantially equal total amounts of optical energy. The controller performs first and second projecting operations. The first projecting operation involves simultaneously projecting first and second cross-sectional sub-images from the first projector onto first and second areas of an image projecting surface, respectively, and the second and third cross-sectional sub-images from the second projector onto the second and third areas of the image projecting surface, respectively. The second projecting operation involves simultaneously projecting the first cross-sectional sub-image from the first projector onto the first area and the third cross-sectional sub-image from the second projector onto the third area. The controller equalizes the number of times the first to third cross-sectional sub-images are to be respectively projected onto the first to third areas.
