GRAPHIC INFORMATION PROCESSING DEVICE FOR FORMING AESTHETIC CURVES, GRAPHIC INFORMATION PROCESSING METHOD, AND GRAPHIC INFORMATION PROCESSING PROGRAM

摘要

To easily form curves preferable for design (beautiful curves or aesthetic curves). A CAD system includes: a receiving unit that receives input of graphic information representing a line figure that includes a curve; a dividing unit that divides the line figure into a plurality of segments and generating a plurality of pieces of segment information corresponding to the plurality of segments; a first shaping unit that shapes a curve in each segment by converting each of the plurality of pieces of segment information through a function defined in terms of a curvature; a second shaping unit that further shapes the plurality of segments by converting each of the converted plurality of pieces of segment information so that a difference between a curvature at an endpoint of one segment represented by the piece of segment information and a curvature at an endpoint of another segment connected to the endpoint of the one segment becomes equal to or smaller than a predetermined threshold; and a display unit that outputs the graphic information representing the line figure that consists of the plurality of shaped segments.
