C++ Raytracer

img

Description

This is a C++ implementation of a raytracer, a computer graphics technique for simulating the way light interacts with objects to generate realistic images. This raytracer supports features like basic shapes (spheres), reflections, shadows, and basic materials.

Features

  • Sphere primitive
  • Materials (Matte, Specular, Dielectric)
  • Shadows
  • Reflections
  • Anti-aliasing
  • Depth of Field
  • PNG output
  • Multi-threading

Getting Started

Prerequisites

  • C++17 or higher
  • CMake (for building)

Building

  1. Clone this repository:

    git clone https://github.com/PotatoPresident/Ray-Tracer
cd Ray-Tracer

  2. Create a build directory and generate build files with CMake:

    mkdir build
cd build
cmake ..

  3. Build the project:

    cmake --build .

Usage

./raytracer.exe
./raytracer.exe <image_width> <image_height> <samples_per_pixel> <max_depth> <threads>

Options

  • image_width : Set the width of the output image (default: 100).
  • image_height : Set the height of the output image (default: 100).
  • samples_per_pixel : Specify amount of samples for each pixel (default: 10).
  • max_depth : Set the maximum amount of times a ray can bounce (default: 10).
  • threads : Set the number of threads to use for rendering. Set to 0 to use maximum suggested (default: 0).

Scene File Format

The scene file is a text file containing a description of the objects and their properties. Here is an example:

Examples

./raytracer.exe
./raytracer.exe 1920 1080 100 50 0
