CSE-410 | Computer Graphics

This repository contains my implementations of the assignments of the course CSE-410: Computer Graphics by BUET.

• Offline-1 | OpenGL

  camera movement rolling a ball magic cube

  
  • Problem Specification

  • How To Run?

    • enter into offline-1|opengl directory
    • run the following command

      ./build_and_run.sh <source_file_name>

      e.g.

      ./build_and_run.sh magic_cube.cpp

  • File Description

    • Task-1 | camera movement
    • Task-2 | rolling a ball
    • Task-3 | magic cube

• Offline-2 | Rasterization

  z-buffering scanline algorithm

  
  • Problem Specification

  • How To Run?

    • enter into offline-2|rasterization directory
    • run the following command

      ./build_and_run.sh -d <directory_name> <scene_file_path> <config_file_path>

      e.g.

      ./build_and_run.sh -d output1 ios/1/scene.txt ios/1/config.txt

  • File Description

    libGG is a tiny version of openGL library I implemented specifically for this offline.
    • bitmap_image.hpp - external bitmap image library
    • libggutil.hpp - declartion of utility classes and functions for libgg library
    • libggutil.cpp - implementation of utility classes and functions for libgg library
    • libgg.hpp - declartion of libgg library
    • libgg.cpp - implementation of libgg library
    • scene_parser.cpp - parse scene.txt and config.txt files and generate c++ code with libgg library

• Offline-3 | Ray Tracing

  phong shading reflection

  
  • Problem Specification
  • How To Run?
    • enter into offline-3|ray-tracing directory
    • run the following command

      ./build_and_run.sh <input_file_path> <output_file_directory>

      e.g.

      ./build_and_run.sh ios/scene_test.txt output

    • NOTE: Unlike mentioned in spec, my implementation doesn't expect blank line at the end of object, light and camera description in the input file.
