Abstract
It is very important for virtual character designers to generate 3D face models interactively and creatively in real-time. This paper investigates the use of sketch-based interface in 3D face modeling and focuses on how to map 2D sketchy features onto a 3D model. A mapping mechanism on the basis of contour lines is proposed. Representative points of the input are extracted, which retain the global and local shape originalities. Then the outer and inner contours are extracted automatically from a given 3D face model (as a template model), and a set of feature points are determined according to the 2D representative points. The displacements between the 2D representatives and the 3D feature points are calculated and used as the control parameters of model deformation. A novel face model is finally created by means of deforming the given model. The experiments show the efficiency and effectiveness of our approaches.
