WoP: Walk on Probes

This repository contains the official implementation of our SIGGRAPH 2026 paper "Probe-based Walk on Spheres for Efficient Path Reusing".

Build

Our code was developed and tested on Windows 11 with Clang 20.1.0. To build the project, initialize the submodules and run CMake from the repository's root directory:

git submodule update --init --recursive
cmake -B build -G Ninja -DCMAKE_BUILD_TYPE=Release
cmake --build build

Usage

We provide demo scenes under data/exp_scenes/ and solver configurations under configs/. For example, to run the algorithm described in the paper, you can execute:

./build/bin/Release/demo.exe --config configs/wopc.json

You can also override the parameters defined in the configuration file. For example:

./build/bin/Release/demo.exe --config configs/wopc.json -s data/exp_scenes/2d_1_engine
