3D printing can make an action figure copy of your body and face, but the hair usually ends up looking like a Lego minifig wig. The mad scientists at Disney Research just solved that, with an algorithm so powerful it can trace your hair’s shape and color with ultra-realism.

The research team at Disney Research Zurich and the University of Zaragoza took inspiration from the classical sculptors, who created lifelike representations of hair using solid forms rather than trying to capture the shape and size of individual hairs:

Beginning with several color images captured of the subject’s head, the system firstcomputes a coarse geometry for the surface of the hair. Color information from the images is then added, matching the colors to the rough geometry to the extent possible. In the next step, color stylization, the level of detail is reduced enough to enable the representation to be miniaturized and reproduced, while preserving the hairstyle’s defining features. Finally, geometric details are added in a way that is consistent with the color stylization.

The result is a delightfully realistic 3D-printed figurine. The technique can be used for hairstyles, facial hair, and even recreating fuzzy objects like stuffed animals, as shown in the Disney Research video below.

Disney Research will present this technique at SIGGRAPH 2014, the computer graphics conference in Vancouver that starts tomorrow. Pretty soon, you could have a 3D printed mini-twin for every hairstyle you’ve ever tried. [Disney Research]
