An ImGui front-end to the pmTracer library made with the nCine.

Poor Man's Tracer is a very simple and minimal ray tracing and path tracing library based on Ray Tracing from the Ground Up by Kevin Suffern.

• Don't forget to compile the nCine with -D NCINE_DYNAMIC_LIBRARY=OFF so that ncTracer can access the OpenGL and threading private API.
• For testing purposes there are some defines that you can change
  • In SceneContext.cpp you can change the value of THREADING_TYPE to switch between single threaded, tiled single threaded and tiled multi-threaded
  • In ThreadManager.h you can change the value of STD_THREADS to switch between std::thread and ncine::Thread
