Path Tracer

This is my path tracer implemented under the architecture of Ray Tracing in One Weekend Series v3.2.3,

with features:

• geometric primitives: box, sphere, triangle, rectangle...
• materials: Cook Torrance PBR lighting model (diffuse\glossy\specular), dielectric...
• fog & smoke (constant density)
• physical camera: depth of field, motion blur
• multiple importance sampling
• bounding volume hierarchy
• multi-thread accelerated rendering with OpenMP

Sample Images

Build

Clone this repo and enter the directory, then run:

mkdir build
cd build
cmake ..
make

To render sample images, run:

PathTracer cornell_box > cornell_box.ppm

Note that to enable OpenMP, modify CmakeLists.txt to include the flag -fopenmp for gcc, or /openmp for MSVC.
