Simple raytracer

A simple ray tracing "engine" written in C++ and OpenCL using boost.compute.

Showcase

Building

This project needs boost and OpenCL to be installed on the system.

$ git clone https://github.com/davawen/Simple-Raytracer
$ meson setup build
$ meson compile -C build

To run the project, just launch the executable:

$ ./build/tracer

Note the you must be in the project's directory to run it, as it reads src/render.cl.

Features

• Basic shape intersections (plane, sphere, box)
• Metallic, specular and refractive materials
• [-] Model loading (.stl and .obj files)
  • Wavefront (.obj) meshes need to be triangulated, and don't support materials
• Light accumulation (eliminate noise over time)
• UI and gizmos to place objects

Future plans

• Acceleration structure (BVH)
• Texture support
• Scene saving and loading
• Denoising
