Show HN: VoxelTV – Turn music videos into interactive 3D voxel sculptures

VoxelTV, a browser-based creative tool that transforms music videos into interactive 3D voxel sculptures, launched on Hacker News on August 25, 2026, posted by developer jojohack.

Per the Show HN post, the app renders each video as a voxel grid using Three.js. Color data is sampled directly from the current video frame, while the height of each voxel column is derived from depth maps generated by Depth Anything, an AI-based monocular depth estimation model. The result is a sculpture that shifts in real time as the video plays.

The project also supports local use: according to the Show HN submission, jojohack recently added the ability to create user-generated voxel versions of videos entirely within the browser, without requiring any server-side processing. The live demo is hosted at voxeltv.surge.sh.

The tool sits at the intersection of generative art and AI-assisted depth perception. By pairing a real-time rendering library (Three.js) with Depth Anything's depth inference, VoxelTV converts flat 2D video content into navigable three-dimensional structures — a workflow that, per the post, runs fully client-side in the browser.

No funding, team size, founding date, or commercial plans were mentioned in the submission. The project appears to be an independent side build by a solo developer. No comments had been posted to the Hacker News thread at the time of publication.
