Claim One:
1. A method of managing drawing information in a drawing information management system including a graphic processor and a storage unit, comprising steps of: (a) determining a domain which covers a whole drawing data to be subjected to processing; (b) dividing said domain into a first number of meshes of a same size; (c) determining the number of the meshes traversed by a vector constituting a part of said drawing data; and (d) comparing said number of the meshes with a predetermined value, wherein (i) when said number of the meshes is not greater than a predetermined value, the current mesh size and the positions of the meshes traversed by said vector are stored in said storage unit a drawing information of said vector, and a next vector constituting another part of said drawing data is selected to execute the aforementioned steps (b), (c) and (d), while (ii) when said number of the meshes exceeds said predetermined value, said domain is divided into a second number of meshes of a same size, which number differs from said first number, being then followed by execution of the aforementioned steps (c) and (d), and (iii) when the drawing information have been determined for all the vectors constituting said drawing pattern, storage of said drawing information into said storage unit is completed.
