3D Depth Generator
Estimate depth from one flat image, then re-project it into two eye views. Export a red-cyan anaglyph, an animated wiggle that needs no glasses, a stereo pair, or the raw depth map.

A clear foreground against a distinct background works best
Maximum horizontal parallax between the two eyes
Depth that sits flat on the page; nearer pops out
Depth here is inferred from brightness, not measured. It produces a convincing stereo effect on images where lighting happens to follow distance, but it is an estimate rather than a real depth capture.

Needs red-cyan glassesUpload an image to begin
Anaglyph needs red-cyan glasses. The wiggle animation works with the naked eye.
How It Works
Upload a Photo
Portraits and scenes with clear foreground and background work best.
Tune the Depth
Set which plane sits at zero parallax and how strong the separation is.
Export
Anaglyph PNG, a stereo pair, or side-by-side for a VR viewer.
Frequently Asked Questions
Is this true 3D from a single photo?
No, and no browser tool can be. A single photo has no measured depth, so depth is inferred from luminance. Bright areas are treated as nearer by default and you can invert that. The result is a convincing stereo effect, not a metric depth capture.
Why does the red-cyan version need glasses?
An anaglyph packs both eye views into different colour channels, and the glasses are what separate them again. That is inherent to the technique. If you want an effect with no glasses, use the wiggle animation.
What is the focus plane?
The depth that receives zero horizontal shift. Everything nearer pops forward and everything further recedes behind the paper. Put the focus plane on your subject to keep it sharp.
What causes the halos around edges?
Shifting pixels sideways exposes areas that were hidden in the original. Those gaps are filled from the nearest visible neighbour, which can look stretched. Lower the strength or raise the depth smoothing to reduce it.
Which photos work best?
Images where brightness happens to correlate with distance: a lit subject against a darker background, or vice versa with invert enabled. Flat, evenly lit images have little for the estimator to work with.
Can I print an anaglyph?
Yes. Print on white stock with accurate colour, since the effect depends on clean red and cyan separation. Test with your glasses before committing to a run.
