Cavalry

A GPU Ray Tracer written in CUDA

Cheers love, the cavalry's here! -- Tracer (Lena Oxton)

Features:

• GPU Bounding Volume Hierarchy construction using radix trees (Aila 2012)

• GPU BVH Optimization by restructuring (Aila 2013)

• (Partial) compatibility with PBRT v3 scene definition files.

• Reinforcement Learning Guided Path Tracing

This is submitted as my 4th year project at the CS department of the University of Oxford.

Installation

mkdir build
cd build
cmake ..

And then make or open solutions file using IDE.

For Windows, a pre-built executable is available in exe/

Running Cavalry

Cavalry --input <input .pbrt file> 

Optional flags:

• --output <output .png file>

• --spp <amount of samples per pixel>

• --integrator <path or rlpath>

  path corresponds to a path-tracing integrator

  rlpath corresponds to a reinforcement learning path-tracing integrator

• --bvh-opt-rounds <amount of BVH optimization rounds>
