Warnock's Algorithm
A divide and conquer algorithm
Warnock (PolyList PL, ViewPort VP)
If (PL simple in VP)
then Draw PL in VP,
else
Split VP vertically and horizontally into VP1, VP2, VP3, VP4
Warnock (PL in VP1, VP1)
Warnock (PL in VP2, VP2)
Warnock (PL in VP3, VP3)
Warnock (PL in VP4, VP4)
End
What does "simple" mean?
No more than one polygon in viewport
Scan convert polygon clipped to viewport
Viewport only 1 pixel in size
Shade pixel based on closest polygon in the pixel
Hi, can you give me a quote for an E-R diagram

Threaded Binary Tree:- By changing the NULL lines in a binary tree to special links known as threads, it is possible to perform traversal, insertion and deletion without using
Example: Insertion of a key 33 into a B-Tree (w/split) Step 1: Search first node for key closet to 33. Key 30 was determined. Step 2: Node pointed through key 30, is se
that will determine the volume of the sphere or the volume of cone or volume of pyramid depending on the choice of the user
Q. Write down an algorithm to insert a node in between any two nodes in a linked list Ans. Insertion of a the node after the given element of the listis as follows
Asymptotic notation Let us describe a few functions in terms of above asymptotic notation. Example: f(n) = 3n 3 + 2n 2 + 4n + 3 = 3n 3 + 2n 2 + O (n), as 4n + 3 is of
Time Complexity, Big O notation The amount of time needed by an algorithm to run to its completion is referred as time complexity. The asymptotic running time of an algorithm i
The complexity of multiplying two matrices of order m*n and n*p is mnp
Explain an efficient way of storing two symmetric matrices of the same order in memory. A n-square matrix array is said to be symmetric if a[j][k]=a[k][j] for all j and k. For
