Assignment-1

Visualisation of 2D Vector fields using Bresenham's algorithms

Course Assignment for IS F311- Computer Graphics @ BITS Pilani, Hyderabad Campus.

Objective:

• Implementing Bresenham's midpoint line and circle algorithm.
• To make a crude visualisation of vector fields made using Bresenham's lines and circles.
• To try out different samplings of the 2D space and record the results.

How to run:

• The project is tested on Linux and built in C++ using the following libraries:
  • GL
  • GLUT
  • CMake
• To build : g++ <main>.cpp -lGL -lglut -lGLU
• Run the output executable : ./a.out

Challenges faced:

• For non-linear input functions, the vector field takes time to render on the screen.
• For polynomial functions with higher degree the contraints need to be changed accordingly to render the output in lesser time.
• For sine and cosine functions the algorithm rounds values to integers -1,0,1.
• It may round the values of center and radius depending upon the function
