The algorithm is applied in the segmentation of Magnetic Resonance Imaging of human brain for the 3D reconstruction on dependent of different human tissue structures, in which the problem on wraps between different tissues and fuzzy edges between the different regions in medical volume data may better be settled, which can not be well done by the typical"hard"segmentation using binary logical representation.(3) An accelerated algorithm of volume rendering with X-ray perspective and Phong shading effect based on textures mapping and blending is presented for realizing 3D reconstruction of medical volume data by 2D texture mapping and blending, in which the accelerated algorithm of window transformation is utilized to computing voxels' gray scales and opacities to produce X-ray perspective images, and Phone illumination model is used to import world light sources and an unit spherical surface under the same shading environment as the actual volume rendering is employed to simulate the real reflectional light of per-voxel so that 3D reconstruction possesses illumination effect in the world. Furthermore, 3D matrix transformations of degree rotation and other operations of 3D object are studied, and a fast equivalent method of corresponding shading correction is brought forward to improve its interaction speed in volume rendering process.

PRT considers all incident lighting from the upper hemisphere on each point of the surface resulting in smooth shadow. In this method, by considering the way light source is blocked by other objects and how it reflect on object surfaces, one can create self-shadowing and self-interreflection effects.

PRT因为考虑物体每一个表面点单独受到四面八方光线的影响，因此所呈现的明暗效果非常平滑，同时此光照技术也能够考虑每一个表面点光源被物件其他部分遮住的情形以及受到其他物件反射光线之影响，因此能够表现从来无法以及时运算呈现的自身阴影与反射光。
