Overview

Simple C++ ray tracing framework and demos.

Features

• Multithreading support;
• Supersampling support;
• CUDA support (Windows only).

Demos

1. Pretty spheres

Here we render a bunch of spheres with random color, roughness and refraction index.

• Global illumination - scattering on the matte and reflective surfaces;
• Directional light source - light (shadow) rays;
• Specularity - Cook-Torrance approximation.

2. Glass spheres

Everything as in Pretty spheres demo + refraction on glass surfaces.

Command line arguments

-w - window's width (default = 1024);

-h - window's height (default = 768);

-s - supersampling samples (in row) count (default = 2, 2x2 samples here);

-t - ray tracing threads count (default = 4);

-d - demo index (default = 1);

-c - enable CUDA acceleration (only Windows supported).

Controls

• Esc - exit;
• T - rerender scene;
• Q - rerender scene in high quality (at least 10x10 samples).

Supported platforms

• Windows (msvc in Visual Studio 2017);
• MacOS (clang).

Requirements

• CMake 3.12+;
• CUDA compatible device (for Windows with CUDA_ENABLE flag in CMake, tested on CUDA 10.0);
• OpenGL 4.1 support.
