Algorithm for Z-Buffer Method
(a) Initialize every pixel in the viewport to the smallest value of z, namely z0 the z-value of the rear clipping plane or "back-ground". Store all values in the z-buffer.
(b) Start polygon loop i = 1 to n, n being the number of polygons.
(i) Scan convert each pixel, that is, find the value of z for each (x, y) for the polygon.
(ii) Compare it with the z′ value stored for that (x, y). If z < z′, then the new point is closer to the viewer than the previous point, and hence is visible in front of the previous point; reset z′ to the new value.
(c) End loop on i.
(d) Plot only the final z′ values in the z-buffer for all (x, y) in the viewport, with the appropriate colour or gray scale and other attributes.
Suppose that you want to develop a program that accepts a postfix expression and asks values for variables in the expression. Then you need to calculate the answer for the expressi

Arrays are simple, however reliable to employ in more condition than you can count. Arrays are utilized in those problems while the number of items to be solved out is fixed. They

Q. The reason bubble sort algorithm is inefficient is that it continues execution even after an array is sorted by performing unnecessary comparisons. Therefore, the number of comp
