C++14 library which uses the ray marching approach for generating images.

General Information

• CPU-bound rendering library
• uses OOP principles for describing the scene

Add following library files to your project:

• light.h
• light.cpp
• object_interface.hpp
• ray_marcher.h
• ray_marcher.cpp

Add the files to your cmake, also include OpenMP.
CMake 3.9+ Syntax:

find_package(OpenMP)
if(OpenMP_CXX_FOUND)
    target_link_libraries(YOUR_TARGET PUBLIC OpenMP::OpenMP_CXX)

• objects
• lights objects
• ambient color
• camera properties (position, rotation, scale)
• field of view
• far clip (furthest distance visible to camera)
