Drawing data producing apparatus and drawing data producing method
First Claim
1. A drawing data producing apparatus comprising:
- a plurality of sequence tables into which sequence data indicating processing sequences of a plurality of blocks obtained by dividing a picture are written for each object of the picture having addresses corresponding to information in a Z-direction of three dimensional coordinates of representative pixels of the respective blocks; and
sorting control means for carrying out, in a stepwise manner, sorting in a depth direction (Z-sorting) of a plurality of sequence tables therebetween, so as to produce drawing data by stepwise Z-sorting of the plurality of sequence tables therebetween.

Abstract
A drawing data producing apparatus having a plurality of sequence tables into which sequence data indicating processing sequences of a plurality of blocks obtained by dividing a picture are written every objects constituting the picture with information in a Z-direction in three dimensional coordinates of representative pixels of the respective blocks being as addresses; and a sorting control section for carrying out, in a stepwise manner, Z-sorting of a plurality of sequence tables therebetween, to produce drawing data by stepwise Z-sorting of a plurality of sequence tables therebetween. Thus, even in the case where objects physically divided are present at depths close to each other, this drawing data producing apparatus excludes interference of polygon unit, thus making it possible to produce drawing data of excellent picture quality.
