Redline is a path tracer written in C++ as a educational and hobby project. It takes GLTF 2.0 scene files as a input and renders them with a unbaised path tracer. The software itself is not particularly practicle to use in it's current state, but the source code may be useful to somebody else trying to learn about offline rendering. It currently only builds for Windows, but has been written with cross platform compatibility in mind (SDL for window management).
