Computer Graphics Programming Assignment 1

Ques 1. (3 marks)

This question is implemented by Itisha Patidar (B17CS026).

The midpoint line drawing algorithm is implemented in C++. The program randomly generates x and y-coordinates for 2 points with in the range 10-400 for both x and y coordinates. It then draws the line from point-1 to point-2.

The code can be found in file named Line_Drawing.cpp

Output:

Line_Drawing_Output

Ques 2. (5 marks)

This question is implemented by Geetesh Gupta (B17CS024).

Part A

The triangle rasterization using Boundary Box Algorithm with barycentric coordinates is implemented in C++.

The program generates a triangle with coordinates within the range 10-400 for both x and y coordinates.

The code can be found in file named Triangle_BoundaryBox.cpp

Part B

The triangle rasterization using extended Midpoint Line Algorithm is implemented in C++.

The program generates a triangle with coordinates within the range 10-400 for both x and y coordinates.

The Midpoint Line algorithm first generates the boundaries using the coordinates and then, row-by-row scan to fill the pixels lying between the boundaries generated.

The code can be found in file named Triangle_ExtendedLine.cpp

Part C

The triangle rasterization using Boundary Box Algorithm and applying SuperSampling at 4x resolution is implemented in C++.

The program generates a traingle with coordinates within the range 10-400 for both x and y coordinates by first generating a buffer matrix with 4x size and coordinates, applying the Part A algorithm and then averaging back in terms of 4x4 matrix and displaying the result.

The code can be found in file named Triangle_Supersampling.cpp

Output:

Triangle_Output

Ques 3. (2 marks)

This question is implemented by Itisha Patidar (B17CS026).

The midpoint Circle drawing algorithm is implemented in C++. The program generates a circular arc from 135-215 degree of a circle centered at origin and has radius 100.

The code can be found in file named Circle_Drawing.cpp

Output:

Circle_Drawing_Output

Steps to run the code

Standard OpenGL for CPP procedures are to followed to run the files.

Steps to run in Windows:

  1. Setup OpenGL in CodeBlocks or Visual Studio.
  2. Create a freeglut Project.
  3. Import file then build and run the project.

Steps to run in Linux:

g++ filename.cpp -lGL -lGLU -lglut
