RTOW Revisited — A Glimpse Into the Journey

This short video captures a live preview from the current stage of my RTOW Revisited project — a hybrid GPU path tracer built in C++ and GLSL, running on macOS.

You’re seeing the final render stage of Chapter 11 from the Ray Tracing in One Weekend series, now reinterpreted through my own system.

The interactive ImGui interface controls the accumulation, tonemapping (ACES operator), and exposure parameters in real time.

This marks the first phase of my broader exploration: building a modular rendering framework that connects technical precision with creative intent.

The next step — coming in Devlog 01 (November) — will dive into the architecture, performance tuning, and the first Metal port comparison.

For now, here’s a look at the tracer running live — each frame resolving light paths progressively, one sample at a time.

If you’d like to follow the research process in depth, full devlogs and technical PDFs will be shared here next month.
