Abstract


Realistic 3D face reconstruction techniques is the hot spot of research in the field of computer graphics . For human face realism reconstruction method based on grid model to analyze the positioning of the facial three-dimensional grid simplified method and the local organ characteristics , the model of the human eye and motion control and hair generation technology , to achieve a three-dimensional model based on the grid the face realistic modeling system has important theoretical significance and practical value . The main research work as follows : (1) Based folded mesh simplification algorithm simplifies the recovery of the head model, to achieve the purpose of reducing the mesh vertices and triangular facets . Applications based on template the organ matching method to achieve fast positioning of the eye area . ( 2) an improved simulation based on the movement of the sphere photorealistic eyes , respectively, of the human eye eyeballs and eyelids with a sphere and parabolic approximation , its movement is controlled by the feature points on the eye and eyelids , to achieve a three-dimensional human eye modeling and control of the movement . ( 3) a share generation algorithm based on generalized cylinder hair , the scalp is divided into a number of small squares and shares growing point structure hair generalized cylinder , respectively, to the center of each square , using the cylinder individually hair shares simulation to generate realistic hair model . (4 ) an improved generation algorithm based on NURBS surfaces overall hair , the algorithm using the NURBS parametric surfaces analog overall hair , control hair , use alpha mapping is finished rendering , realistic 3D feature points on the surfaces The hair quickly generate . (5) combined with the actual needs of the realistic treatment , as a tool for Visual C 6.0 and OpenGL , design and 3D face eyes hair realistic modeling system and the validation involved realistic processing algorithms .
