PLOTTING METHOD OF POLYGON, TRIANGLE AND QUARDRANGLE MESH

摘要

PURPOSE: To reduce correction processing for the vertex data of a divided triangle and to speed up plotting processing for a polygon in the case of executing monochromatic face filling plotting. ;CONSTITUTION: When a plotting means 2 plots each triangle based upon the vertex data of each triangle obtained by dividing a polygon by a dividing means 1 in order to execute the face filling plotting of the triangle, color data having the plotting color information of the polygon are added to the vertex data of respective triangles divided by the means 1 and outputted to the means 2. When monochromatic face filling plotting is set up as a prescribed plotting condition, the means 2 plots respective triangles by plotting colors based upon the color data added to the vertex data of respective triangles.;COPYRIGHT: (C)1995,JPO
