3D printing or addictive manufacturing (AM) is a process of making a three dimensional solid object of almost any shape from a digital file.
3D printers uses a variety of very different types of additive manufacturing technologies, but they all share one core thing in common: they create a three dimensional object by laying down successive layers of material until the entire object is created. It’s much like printing in two dimensions on a sheet of paper, but with an added third dimension: UP. The Z-axis.
While 3D printing got quite some grounds by capturing near to real life objects but the hair usually didn’t got the details because it couldn’t handle complex hairstyles.
Nowadays, Miniature statues with a person’s likeness are produced by scanning the individual’s face with a specialized camera or by using some other sensors to create a 3D model. These facial features can then be applied to a figure that is produced on a 3D printer, but hair is beyond the capabilities of most systems, so hairstyles either must be roughly approximated or replaced with a pre-existing template.
Now, researchers at Disney Research Zurich and the University of Zaragoza came up with an algorithm so powerful that it can trace your hair’s shape and color with ultra-realism and you’ll get most accurately 3D Print Stylized Hair. It can capture individual hair style in the manner suitable for Miniaturization, Physical reproduction while still preserving the visual look of the hair.
Disney Research will present their new method at ACM SIGGRAPH 2014, the International Conference on Computer Graphics and Interactive Techniques in Vancouver, Aug. 10-14.
This approach extends traditional pipeline by introducing three new steps.
- Color Initialization
- Color Stylization
- Geometry Stylization
Beginning with several color images captured of the subject’s head, the Disney Research system first computes 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.
