Leikstöð

Turns a video into a PlayStation 1–style scene: everything becomes a chunky, low-poly 3D model with wobbly vertices, warped textures, fog and dithered 15-bit color.

▶ Run it in your browser: sungammagnus.github.io/leikstod

Nothing is uploaded. The video, the depth model and the rendering all run locally in your browser.

How it works

1. Each frame goes through Depth Anything V2, which estimates how far away every pixel is.
2. That depth pushes a coarse triangle grid in and out, turning the frame into a 3D surface.
3. In Layered fill mode, the subject is cut free at depth edges and given rounded sides. A background layer is rebuilt behind it, from background seen in earlier frames or guessed from the surroundings.
4. The scene is rendered with PS1 quirks: vertices snapped to the pixel grid, affine (non-perspective) texture mapping, flat per-triangle color and shading, fog, and ordered dithering at a low resolution.

Using it

• Open video, or drop a file onto the view. Webcam works for live preview.
• Drag the view to orbit the camera; double-click to reset it.
• Value boxes: drag up or down to change (Shift for fine), double-click or press Enter to type, arrow keys to step.
• Settings are saved in your browser, so they carry over to the next video and the next visit. Reset to defaults at the bottom of the controls restores the originals.
• Timeline: Play (Space) and a playback speed menu sit on the left. Speed only affects the preview; exports keep the original timing.
• In / Out (or the I and O keys) mark the range to export, and the range edges can be dragged to adjust it. Clear (X) removes it. Playback loops inside the range.
• Export MP4 renders every frame of the range. Output quality: Low = 2× render size, Medium = 4× (up to 4K), High = 1080p.

Requirements

• A recent Chrome or Edge on desktop. WebGPU makes depth estimation fast; without it the app falls back to a much slower CPU path. MP4 export needs WebCodecs.
• The first load downloads the depth model (about 100 MB); after that it's cached.
• No audio in exports yet.

Running locally

It's a single index.html with no build step. Serve the folder over HTTP (the model cache needs a secure context, which localhost counts as):

python3 -m http.server 8000

Then open http://localhost:8000.

Built with

three.js, Transformers.js, Depth Anything V2 and mp4-muxer. Interface in the Sungam graphite style.
