# ncTracer

An [ImGui](https://github.com/ocornut/imgui) front-end to the [pmTracer](https://github.com/encelo/pmTracer) library made with the [nCine](https://github.com/nCine/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_](http://www.raytracegroundup.com/) by Kevin Suffern.

## Notes

* 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`
