3D virtual face modeling technology and application

3D face modeling in computer graphics and virtual reality technology is a hot of research. In this paper, we get the original three-dimensional face data through optical scanners. Due to a variety constraints of conditions (light, face of the rough parts), there are many empty parts of the face. In this paper, we use Hermite cubic spline interpolation algorithm to repair three-dimensional facial model hollow parts, and use the shortest path algorithm to draw three-dimensional face of the grid. Established by the three-dimensional face model can be applied to the digital home, the emotional human facial expressions, medical plastic surgery and other fields.
