For given following 5 circles, explain how Z-buffer algorithm works? For all circles' centres X and Y coordinates are same. For yellow circle Z-coordinate for centre is 2, for black circle Z-coordinate for centre is 1, for green circle Z-coordinate for centre is 3, for red circle Z-coordinate for centre is 4. How final geometry does looks on screen after applying Z-buffer algorithm? For given following 5 circles, explain how Z-buffer algorithm works? For all circles' centres X and Y coordinates are same.
