Raytracing

This project contains:

• Basic raytracing,
• Multithreading
• Unit testing,
• Lights (directional, punctual, spot),
• Colorized lights,
• Objects (sphere, plane, triangle),
• Reflection,
• Refraction,
• SFML Window,
• Continuous integration (see Github Actions),
• Transparency,
• Recursivity,
• Movable camera,
• SSAA anti-aliasing,
• OBJ loading,
• Config file for objects in parameters,
• Modern c++ (c++17).

Multithreading

To enable multithreading, please go to the "Config.h" file.

Template

This project uses the cpp-template of Dorian Bachelot.

Build

Dependencies

• CMake 3.12.0 or newer,
• Conan,
• Python (optional).

Quick start

Firstly, clone this repository (help here).

For Linux (debian-like)

Install dependencies:

> sudo apt-get install cmake g++ python
> sudo pip install conan

Build (in the 'build' folder, for example):

> cmake ..
> make

Binaries are in the 'build/bin' folder.

For Windows

Install dependencies:

• CMake: https://cmake.org/download/,
• A compiler (for example MSVC): https://visualstudio.microsoft.com/,
• Conan: https://conan.io/,
• Python: https://www.python.org/ (optional).

Build (in the 'build' folder, for example):

> cmake ..
> cmake --build .

Binaries are in the 'build/bin' folder.

For MacOS

Install dependencies (we will use Homebrew here) :

• XCode: https://apps.apple.com/app/xcode/id497799835

> brew install python
> brew install conan

Build (in the 'build' folder, for example):

> cmake ..
> cmake --build .

Binaries are in the 'build/bin' folder in the bundle ".app" format.

File format

To initialize the objects and lights, you need to specify the config file path. The '|' are replaced by blank space in the file.

The file can contains these objects and lights :

• Color definition : defined name | undefined r g b

• Vector definition : x y z

• Structure definition : metal reflectivity | transparent reflectivity refractivity transparency

• Punctual format : Name | Intensity | Color | Vector Coordinates

• Spot Format : Name | Intensity | Color | Vector Coordinates | Vector direction | Angle

• Directional Format : Name | Structure type | Color | Vector Coordinates A | Vector Coordinates B | Vector Direction

• Shere Format : Name | Structure type | Color | Vector Coordinates | Radius

• Plane Format : Name | Structure type | Color | Vector Coordinates | Vector Normal

• Model Format : Name | Structure type | Color | File model path | Vector Coordinates | Vector Angle | Scale
