WebOur Z-Buffer has, by definition, the same size as our image: 1 case. Each case of the Z-Buffer contains one pixel's depth and each case is associated with one image's pixel. First, we initialize the (only one) case of our Z Buffer at the maximum value we can store in its cases (depending on the Z Buffer's type, on the OS, etc.: double/float ... WebAlgorithm. Step 1 − Initialize the value of seed point s e e d x, s e e d y, fcolor and dcol. Step 2 − Define the boundary values of the polygon. Step 3 − Check if the current seed point is of default color then repeat the steps 4 and 5 till the boundary pixels reached. If getpixel (x,y) = dcol then repeat step 4 and 5.

WebA polygon layer can contain single polygon or a combi-nation of two or more adjacent polygons. A single poly-gon is made up of multiple poly-lines. Initially, the algorithm always considers a single polygon when form-ing a buffer around it. A single polygon from a polygon layer and the buffer width are required as input to the algorithm.
