Should contain at least 10 programs development in C++. Some Sample practical are listed below.
1. Write a program with menu option to input the line coordinates from the user to generate a line using Bresenham’s method and DDA algorithm. Compare the lines for their values on the line.
2. Develop a program to generate a complete circle based on
a. Bresenham’s circle algorithm b. Midpoint Circle Algorithm
3. Implement the Bresenham’s/DDA algorithm for drawing line (programmer is expected to shift the origin to the center of the screen and divide the screen into required quadrants).
4. Write a program to implement a stretch band effect. (A user will click on the screen and drag the mouse/arrow keys over the screen coordinates. The line should be updated like rubber-band and on the right-click gets fixed).
5. Write program to perform the following 2D and 3D transformations on the given input figure
a. Rotate through θ.
6. Write a program to demonstrate shear transformation in different directions on a unit square situated at the origin.
7. Develop a program to clip a line using Cohen-Sutherland line clipping algorithm between
(x1,y1)(x2, y2) against a window (xmin , ymin)(xmax , ymax).
8. Write a program to implement polygon filling.
9. Write a program to generate a 2D/3D fractal figures (Sierpinski triangle, Cantor set, tree etc).
10. Write a program to draw Bezier and B-Spline Curves with interactive user inputs for control polygon defining the shape of the curve.
11. Write a program to demonstrate 2D animation such as clock simulation or rising sun
12. Write a program to implement the bouncing ball inside a defined rectangular window.
