Merits of z-buffer technique

Question

Write down a short note on the merits of z-buffer technique?

Answer 1

The basic merits of z-buffer technique are as follows:

i) The z-buffer technique is simple to implement and it needs no sorting of surface in a scene.

ii) In z-buffer algorithm, an arbitrary number of objects can be handled since each and every object is processed one at a time. The number of objects is limited merely by the computer’s memory to store the objects.

iii) The implementation of hardware is simple in this technique.

iv) Z-buffer is online algorithm that is, we don’t require loading all polygons at once in order to run algorithm.
