SYCL Path Tracer

C++ & SYCL Monte Carlo Path Tracer

Path tracing engine written in C++. This project was initially written using SYCL. SYCL is a standard written by the Khronos Group that allows one C++ code to be ran on multiple devices including CPUs, GPUs and even FPGA accelerators. Unfortunately, I have been facing issues (discussions with Intel can be found here and here) with SYCL that lead me to reimplement it in pure C++ (the task was pretty much effortless as a SYCL code is already very close to pure C++).

This project has been superseded by my HIPRT-Path-Tracer written with the HIPRT GPU Ray Tracing API and largely expanded in functionalities.
