Rotation and Revolution of Two Wheels following a 'D' Shaped Path - Computer Graphics Experiment

This is a computer graphics lab experiment. The question was to animate both rotation and revolution of two wheels in opposite direction. Both the wheels move in a path in a of shape 'D'. If one moves in clockwise direction, the other moves in counter clockwise direction. The output of the program is as follows:
The program is as follows:

C Program for Rotation of Polygon - 2D Transformation in Computer Graphics

This is a c program for rotation transformation in computer graphics. Rotation is one of the important 2d transformations in computer graphics. The program will tell you how to rotate points or polygon around a point (the pivot point). This CG lab program in c language using the graphics library reads the number of sides of polygon, co-ordinates of its vertices, the pivot point for rotation, and angle of rotation. It displays the original polygon and rotated polygon in different colors in same screen. More Computer graphics lab problems are available under related posts heading.
