%X In the modeling of human brain surface structural status, to solve the problems of information missing, inconvenient observation etc. which were brought by 2D image displaying method such as CT and MRI, this paper proposed a 3D human brain surface model based on D-TIN (Delaunay TIN) partition. According to the hierarchical slicing data of real model. based on the algorithm of discrete fitting, this paper used Delaunay irregular triangulation method to dynamically construct the topologic relationship between the controlling points on the surface of the model and generate the 3D human brain surface model. Then it proceed visualization rendering to the model with OpenGL, and finally 3D human brain real model which could fit the medical demand well. This model directly, clearly, completely reappeared the surface structure of human brain. It exerted an important meaning to the cognition of brain pathological changes, operation guide and the development of cognitive neuroscience.
