Ray Tracer in C++

Overview

This project is a part of the course TNCG15 Advanced Global Illumination and Rendering at Linköping University 2024. The project aimed to create a Monte Carlo ray tracer in C++ from scratch that simulates realistic global illumination featuring transparent, reflective, and Lambertian surfaces.

Usage Windows

Prerequisites

• CMake GUI
• VS 2022/2019

Run it on your machine

1. Clone repo.
2. Create a build directory within the project.
3. Open CMake.
4. Select the TNGC15-Global-Illumination directory as the source.
5. Select the build directory created in step 2 as the build.
6. Press Generate.

Done! Now you can open the solution created in the build directory (.sln file).

Usage MacOS

Prerequisites

• CMake (Install via Homebrew: brew install cmake)
• A C++ compiler (e.g., Clang, included with Xcode Command Line Tools)

Run it on your machine

1. Clone the Repository

2. Install Xcode Command Line Tools
   If you don’t already have Xcode Command Line Tools installed, run:

   xcode-select --install

3. Create a Build Directory
   Create a separate directory for the build files:

   mkdir build
   cd build

4. Run CMake to Configure the Project
   Run the following command to configure the build system, specifying the parent directory as the source:

   cmake ..

5. Build the Project
   Use CMake to compile the project:

   cmake --build .

   or

   make

6. Run the Executable
   After the build completes, you’ll find the executable in the build directory. Run it using:

   ./Raytracing

That’s it! The ray tracer will run and generate the output based on the provided settings.
