CARVE

A raymarched fractal corridor, rendered live on your GPU. Every frame is a pure function of the preset and loop time, so the loop closes seamlessly.

Space or ▶ plays / pauses. Drag the timeline to scrub the loop.
Presets (top right) switch worlds: the cdak corridor, kaleidoscopic lattices, a carved moon.
Rig steers the camera: focal length, fisheye, roll, look-ahead, aim. World carves the architecture. Look and Post grade it.
Audio: pick a file or share a tab, then bind bass / kick / highs to any slider.
Still saves a 4K PNG of the current frame. Download JSON saves your tweaks as a preset.

Rendering to 4K ProRes runs in the desktop app.

This live demo needs WebGPU, which this browser does not have. Try a recent desktop Chrome, Edge or Safari. Meanwhile, here is a recorded loop.
