Painter's Algorithm
As the name suggests, the algorithm follows the standard practice of a painter, who would paint the background (such as a backdrop) first, then the major details (such as a face), and finally the finer details (such as eyes). This is also called Depth Sort or Priority algorithm.
To determine the specific nature of the relative positions of polygons, it is necessary to define the x-, y-, and z-extents, of a polygon in 3-D space as the respective coordinate ranges of the bounding (i.e. enclosing) box. For the quadrilateral ABCD, the x-extent is (xD - xB), y-extent is (yA - yC), and z-extent is (zB - zD). The x- and y-extents of two polygons will enable decisions to be made on their overlap, and the z-extent will define their relative positions with respect to the viewer.
One of the main problems with the linear queue is the lack of appropriate utilization of space. Assume that the queue can store 100 elements & the complete queue is full. Thus, it
We have discussed already about three tree traversal methods in the earlier section on general tree. The similar three different ways to do the traversal -inorder , preorder, and p

An unsorted array is searched through linear search that scans the array elements one by one until the wanted element is found. The cause for sorting an array is that we search

Q. What do you understand by the tree traversal? Write down the procedure for traversing a binary tree in preorder and execute it on the following tree. Ans: Th
Q. Let us consider a queue is housed in an array in circular fashion or trend. It is required to add new items to the queue. Write down a method ENQ to achieve this also check whet
In this unit, we discussed Binary Search Trees, AVL trees and B-trees. The outstanding feature of Binary Search Trees is that all of the elements of the left subtree of the root
