Digital Double overview
Digital Double reconstructs a 3D head from a handful of photos: place pins on facial features across your photo set, solve a camera pose and a head shape that fit all of them at once, then bake the photos into one texture. The result exports as a GLB with a full set of ARKit expression shapes already wired in.
Shooting the photos
Two to eight photos of the same person, from different angles: front, three-quarter, profile. More angles genuinely help the solve; more photos of the same angle don't.
The solve has two hard minimums
A single photo needs at least 6 enabled pins before Kitly can work out a camera pose for it at all. The head shape itself needs roughly a dozen well-placed pins spread across your photos before it moves off a neutral, generic head. Below either threshold, that part of the fit just doesn't happen, silently.
The four tabs
- Pins: place and drag pins on each photo. Covered in Pins and solving.
- 3D: the fitted head in a live viewport, always up to date with whatever tab you're actually on.
- Texture: bake the photos into a skin and eye texture, then color-grade the result. Covered in Texture and lighting.
- Expressions: preview and drive the 51 ARKit expression shapes, and export the finished GLB. Covered in Expressions and export.
A live 3D preview docks under whichever tab you're on, so a pin drag or a texture tweak shows up on the model immediately without switching to the 3D tab to check.
Where to go next
Add your photos in the left panel, then head to Pins and solving to place pins and run the solve.
