Curve-dividing device, curve-dividing method, curve-dividing program and integrated circuit

摘要

A curve division device is provided enabling a multiprocessor system to perform effective curve division on Bézier curves. The curve division device comprises: N (N≧2, N being an integer) processor elements; a reception unit receiving curve information indicating a Bézier curve; a first execution unit causing the N processor elements to execute a division algorithm of taking the curve information as initial input data and repeatedly (i) generating two divided curves by dividing the Bézier curve indicated by the input data, (ii) selecting one of the divided curves according to the assigned setting value, and (iii) defining new input data indicating the divided curve selected for subsequent division, until the divided curve selected by each processor element is different; and a second execution unit causing each processor element to execute a determination algorithm of determining line segments approximating a divided curve resulting from the division algorithm.
