raytracer

Short description

This project is a quite simple (and not very optimized) raytracer. I would say it is more useful to anyone wanting to develop a raytracer and trying to find inspiration or help from other implementations (as I sure did from other projects (I had a very hard time with those nasty cylinders)).

But I would say it can give quite nice results and gained a rather nice interface. As a matter of fact, I used it to render results from other projects (like elplant) and it turns out to be very useful.

Features

• Can load scenes from YAML files
• Handles multiples kind of object (Spheres, Planes, Cylinders, Triangles)
• Transparent (refractive) textures
• Other mostly experimental features (blobs of charged particles, ...)

Requirements

• cmake
• SFML
• Boost (program_options)
• OpenMP
• yaml-cpp

Build

Options: :
  --help                      Display this information
  --demo                      Run demo scene
  -s [ --save ] arg           Disable real time mode and save rendered scene to
                              a ppm (if no filename specified it uses a
                              datetime format)
  -l [ --load ] arg           Load yaml <file>
  -w [ --width ] arg (=1920)  Width of the real time display and/or saved image
