As a domain for computing stylized effects, our algorithm requires
a coarse, low-resolution geometric proxy surface of the hair. This
proxy may be generated with any 3D capture system that provides
geometry and images, such as Li et al. [2013]. In this work, we use
a multi-view reconstruction setup as described in the following.
Ideally, the geometry proxy would be captured in a single shot from
sufficient viewpoints to cover the full head. Since this approach
requires a significant amount of camera and lighting equipment,
we describe a technique that makes use of only limited hardware.
We place ten digital SLR cameras in a quarter-spherical setup and
photograph the subject under four consecutive orientations defined
by 90-degree rotations (Figure 4).
