Cohen Sutherland algorithm
Point clipping is very simple. All you need to check is whether a point is inside the window extremes in x- and y-directions. For line clipping several algorithms have been introduced over the years and many refinements have also been suggested by people in order to improve the performance of the algorithms. One of the first algorithms that is still being used in applications is Cohen Sutherland algorithm.
Write a C program which takes points as input from mouse clicks (left button) and then performs an action. Apply your program to generate a closed polygon as follows: Every time a
A triangle is having the vertices A(0,0) B(1,2) and C (5,2).Magnify the triangle to thrice it''s size while keeping C(5,2) fixed
Implement displacement mapping and bump mapping on a sphere. The displacement can be whatever your choice. The bump map can be whatever your choice as well.
An 8x8 image f[i,j] has gray levels given by the following equation: f [i , j]= ? i-j ? ; i,j=0,1,2,3,4,5,6,7. a. Calculate the gray level value for all the pixels in the 8x8
