Viewpoint Selection for Sketch-based Hairstyle Modeling

Abstract

Hairstyle is an essential factor for representing individuals. It is in demand for ordinary persons who are not experts of professional software on three-dimensional computer graphics (3DCG) to represent hairstyles with flexible hairstyle modeling using 3DCG. We propose a method to realize sketch-based hairstyle modeling efficiently by supporting a viewpoint recommendation technique so that such users can easily perform hairstyle modeling. This method automatically finds appropriate viewpoints by evaluating the shapes of sketches on the projected 2D space. We aim to make this task of sketch-based hairstyle modeling efficient and straightforward because the technique avoids to manually control the viewpoint and prompts users to perform hair modeling intuitively. This paper introduces examples of viewpoint recommendation for two different input sketches.
