A browser-based tool for generating 3D autostereograms (Magic Eye style images) from depth maps. Pure HTML/JS, no build step, no dependencies.
- Built-in presets: box frame, sphere, ring, pyramid, waves
- 3D text with selectable font
- Upload your own grayscale depth map (drag-and-drop onto the canvas)
- Gradient, warped, and pixelated procedural noise
- Random dots (blue-noise distributed for cleaner fusion)
- Checkerboard
- Upload your own tileable image
- Depth Intensity with an Auto button that picks the strongest setting that won't ghost
- Repeat Count, Invert Depth
- Edge Enhancement — Sobel-based outlines that make silhouettes pop
- Depth Shading — tints each pixel by its depth, with decaying echoes through neighboring tiles so the strongest shading lands where the eyes converge
- Texture Scale, Hue Variance, Saturation, Contrast for procedural patterns
- Seed with lock and randomize controls
- Convergence Dots — alignment guides above the image to help your eyes lock in
- Render at 720p, 1080p, 1440p, or 4K (plus square and portrait variants)
- Save as PNG
- Fullscreen view
- Pick a depth preset, type some 3D text, or drag your own grayscale image onto the canvas (white = near, black = far).
- Tweak the sliders. Hit Auto next to Depth Intensity if you're not sure where to start.
- Click Regenerate to roll a new random pattern seed.
- View with the parallel viewing method: relax your eyes and look through the screen as if focusing on something far behind it. The repeating pattern will shift and a 3D shape will emerge. When the convergence dots become three dots instead of two, you're aligned.
