<p>Disclosed are a method, system and device for processing vector graphics in computer image processing. In the present invention, because triangles are only formed in a valid area above a current scanning line in communication with a vertex, unnecessary triangle subdivision is reduced, the calculated amount is greatly reduced because of a lower number and larger size of triangles, the subsequent graphics processing efficiency is higher based on the triangles, the order of movable sides is guaranteed by the order of vertex lower side tables and the order of vertices, and intersection points are ordered to further reduce the amount of calculation. Meanwhile, polygon vertices are quickly ordered using the even/odd fill rule and non-zero fill rule, so that memory data is moved least in a memory, and the graphics processing efficiency is increased.</p> |
