Anti-aliasing method with z-merge

An anti-aliasing method with z-merge, for anti-aliasing a non-vector 3D intersection curve defined by an intersection of a first surface SF 1 and a second surface SF 2 . The vision surface SF 3 is defined by the overlapped first surface SF 1 and the second surface SF 2 . The anti-aliasing method wit...

Summary:An anti-aliasing method with z-merge, for anti-aliasing a non-vector 3D intersection curve defined by an intersection of a first surface SF 1 and a second surface SF 2 . The vision surface SF 3 is defined by the overlapped first surface SF 1 and the second surface SF 2 . The anti-aliasing method with z-merge includes the following steps: (a) setting a depth tolerance value and setting a depth range accordingly; (b) selecting an anti-aliasing area in the vision surface SF 3 near the 3D intersection curve according to the depth range; and (c) merging the first surface SF 1 and the second surface SF 2 within the anti-aliasing area to generate a result surface SFr=F(Zr, Cr, Wr), wherein the result surface SFr is located on the vision surface SF 3 .
