Title: Hatching processing system
Inventor: INOKE MISAO
IPC: G06T17/20
Filed: 1982-05-31
Abstract: PURPOSE:To improve the hatching processing efficiency, by dividing a polygonal figure into many triangles, obtaining the centroid and filling each triangle with a similar triangular linework of shared centroid. CONSTITUTION:The data of each apex of a hexagon, for example, is fed by an operation of a keyboard 2 and then stored in a figure file H of a file device 8 via a control part 3 and a processor 4. A processing part 5 gives an access to the file H and divides the hexagon into 4 triangles. Then the centroid is calculated for each triangle, and small similar triangles sharing said centroid are obtained. When the figure data of the file H is delivered to an output device (drafting machine, etc.) 6, the data of the obtained similar triangle group is also delivered. Thus it is possible to deliver a polygonal figure underwent the hatching processing.
