| titleOfInvention | Algebraic curve rasterization method based on pixel precision |
| abstract | The invention discloses an algebraic curve rasterization method based on pixel precision, comprising the following steps of: inputting an algebraic curve to be plotted and relevant information; limiting characteristic points of the curve into a pixel range to obtain a plurality of characteristic regions containing curve characteristic points; calculating crossed points of the curve and interfaces of the characteristic regions; constructing topology connecting information of the curve on the characteristic regions through the crossed points; determining the direction of the crossed points of the interfaces of the characteristic regions and utilizing a straight-line section to connect the adjacent characteristic regions to obtain a straight-line section fitting curve, wherein the straight-line section passes through the crossed points of the interfaces of the characteristic regions; and optimizing the straight-line section fitting curve, and plotting and displaying the curve. The algebraic curve rasterization method based on the pixel precision can obtain a high-quality curve through Newton iteration and guarantees the smoothness of the curve; and a numerical calculation process with complicated sub-resultant and high ordered equation rooting problems is omitted, and the curve can be conveniently plotted in real time. |
