An experimental path tracing implemention

1. Intro

This program mainly focuses on a physical-based rendering technique, namely path tracing as a coursework.Most of ideas coming from the awesome pbrt-book, such as the concept of BRDF/BSDF, lights sampling, Russian Rouslette and so on.

It's very handy to use. You can get a result simply by typing after building:

./PathTracer ./config/cbox.conf

and you will get the following revised Cornell-Box. :O

2. Dependencies

1. clang++
2. glfw/OpenGL/GLEW
3. jsoncpp
4. tinyobj: a header-only obj loader
5. OpenMP
6. CMake

3. How to build it?

This program is managed by CMake, has been fully tested on macOS Mojave, and is very easy to build :)

mkdir build/
cd build
cmake ..
make -j10

4. The structure

1. ./src/: source codes.
2. ./conf/: diversity scenario settings. Feel free to set up your own scenary and arbitary params as you want.
3. ./model/: all scene files are put into it.

5. Some Results(not perfect)
