Simulating Raytracing and Raycasting in 2D

This project demonstrates 2D Raytracing and Raycasting simulations using OpenGL and GLUT in C++. The program is divided into three parts, each handling a distinct unit of the simulation.

---

Required Libraries

The following libraries are required to build and run the program:

1. FreeGLUT - OpenGL Utility Toolkit for rendering:
   • FreeGLUT Documentation
2. GLEW (Optional) - Manages OpenGL extensions:
   • GLEW Documentation

---

Build and Run Instructions

Scripts Overview

The project contains three scripts, each corresponding to a unit of the simulation:

• one.sh
  Builds and runs the first unit of the program, which is stored in the /builds/one directory.

• two.sh
  Builds and runs the second unit of the program, which is stored in the /builds/two directory.

• three.sh
  Builds and runs the third unit of the program, which is stored in the /builds/three directory.

Steps to Run the Program

1. Clone the repository:

   git clone https://github.com/ItsAash/comp342_raytracing
   cd comp342_raytracing

2. Installing Dependencies: For debain/ubuntu systems:

sudo apt-get install freeglut3 freeglut3-dev

For macOS:

brew install freeglut

3. Make the script executable:

  chmod +x one.sh two.sh three.sh

4. Run the desired Unit:

  ./one.sh

or

  ./two.sh

or

  ./three.sh

Demonstration of the project

Unit 1: Raycasting Demo

• The first unit simulates a basic Ray. It checks whether the ray intersects with the wall or not.

Unit 2: 2D Ray Casting

• This unit simulate the source of the ray, emitting ray in all direction, and checking whether the ray intersects will any wall. This demonstration simulates the visibility of the ray is 0 beyond the wall.

Unit 3: 2D Raycasting for 3D World Generation

• This unit simulates a 2D rays around the 2D world, and generate a 3D world based on the intersection of the Rays.
