Simple toy raytracer using C++11/14 features. Project is composed from rendering library render written in C++11/14 and demo application rt_demo demonstrating capabilities of render library.

Command line utility rt_demo reads description of scene to be rendered from JSON file, and renders the scene to memory buffer. Buffer is then written to output bitmap file.

./rt_demo <scene_file> <output_file>

• Unlimited count of reflected rays.

The C++11 tools library cclib is needed for compilation of rt_demo program. It will be automatically compiled in following compilation steps.

For compilation of a raytracer on Linux perform following steps:

• Download script try_raytracer.sh.

wget https://raw.githubusercontent.com/izuzanak/raytracer/master/raytracer_try/try_raytracer.sh

• Check prerequisites mentioned in the script.
• Execute script try_raytracer.sh.

bash try_raytracer.sh

It will clone two repositories cclib and raytracer, and then compile cclib library, render library and raytracer demo rt_demo.

There are few commands at the end of try_raytracer.sh script, that can be executed after successful raytracer compilation.

Example of rendering scene described by file scene.json to file scene.bmp.
