A physically-based GPU path tracer rendering a Menger sponge fractal inside a Cornell box, built with three-gpu-pathtracer. The renderer progressively accumulates samples to converge on the full global illumination solution, capturing soft shadows, color bleeding between the colored walls, and the intricate self-similar geometry of the Menger sponge.
This version adds touch-based orbit controls for mobile devices alongside the standard desktop mouse controls. Press the “X” key to save the current view as a PNG.
Controls: Click and drag to orbit, scroll to zoom.
