Simple Raytracer

This is a very simple raytracer which was made for my Computer Graphics course in Computer Science university. It uses OpenGL to offload the pathtracing to the GPU. The entire program runs in a GLSL fragment shader. It supports the following features:

• Materials: Matte, reflective, transparent, and glossy;
• Textures, environment maps, including alpha coverage and emission;
• Antialiasing, depth of field;
• Post-process effects: filmic tonemapping and exposure adjustment to convert to LDR;

Its major limitation is the fact that it only accepts sphere and quad primitives as input. Scenes are entirely hard-coded within the GLSL shader.

Renders

Here are some renders which show the renderer's capabilities.

Build and Run

Clone the repository:

git clone https://github.com/LeonardoTemperanza/SimpleRaytracer

Windows

In a Visual Studio Command Prompt, run the build_win.bat script to build and run.

Mac

With clang installed, run the build_mac.sh script to build and run.

Linux

Run the following command:

sudo apt-get install libglfw3 libglfw3-dev

Or, on Red Hat-based systems:

sudo dnf install glfw glfw-devel

With gcc installed, run the build_linux.sh script to build and run.
