Visualization of 3D information can make nonrepresentational data into visual 3D image, which is important for us to analyze and understand these data.

三维信息可视化能够使抽象的三维数据转换为形象的三维图象，从而有利于分析和理解这些数据。

This paper presents a new rendering algorithm by the contrast between the Flat method, Gouraud method and Phong method, through which the color of each pixel can be figured out under the lighting model after the coordinates and normal of every corresponding point on the 3D-object surface have been calculated from the pixels in the range where the 3D-object is projected onto the photo, in order to provide each pixel a real color and get an image with strongest feeling of reality.

本文在对比研究了真实感图形生成中传统的Flat，Gouraud，Phong等明暗渲染方法后，提出了一种新的明暗渲染方法。在图像平面三维物体的投影范围内，由图像的像素坐标求出物体模型对应点的三维坐标及其法矢，然后对每个像素点根据光照模型来计算其明暗度。这种方法能够最大可能的保证图像中每一像素点明暗度的真实性，从而使所生成的真实感图像更加逼真。

Many 3D applications resort to less direct techniques, such as an object list or object hierarchy that users can select from outside of the 3D view.

许多三维应用程序求助于不那么直接的技术，如对象列表或对象层次关系，用户可以在三维视图外从这些列表或关系中选择对象。

The value of the plainradiographs of pelvic was limited in the diagnosis of acetabular fractures and thedecision of pre-operative planing.EBCT images could show acetabular fractures in detail.Onthe basis of EBCT images,rational treatment might be drawed,but working out the detail ofoperative plan,orthopedist had to have rich experience in observing EBCT scan.The imagesof EBCT 3D reconstruction might provide exact guidance to formulate operative plan,thusEBCT 3D reconstuction now was the best method in the diagnosis of acetabular fractures.

骨盆平片诊断髋臼骨折是粗浅的，对制定治疗方案帮助有限；EBCT平扫能显示骨折的详细情况，并由此选择合适的治疗方法，但要制定具体的手术方案，需要临床医生有丰富的阅片经验；EBCT三维重建对制定详细的手术计划可提供正确指导，是目前最理想的诊断髋臼骨折的方法。

Then discusses 3D parametric representation, which includes 3D geometry parametrization and relative position relationship parametrization.

文中首先分析了约束与设计意图的关系及其对产品构成的影响。

Part five discusses 3D model parametric representation, which includes 3D geometry parametrization and relative position relationship parametrization. In the former, the sweeping rules are further formalized, the concept of design parameters and modeling parameters is introduced. In the later, constraint transformation matrices of the position relationships between features are deduced, and the lost of model freedom resulted from the correspending constraint is analysed.

在特征几何参数化中，进一步规范化了特征几何的扫描生成规则，引入了设计参数和造型参数的概念，分析了造型参数向设计参数适时转化的必要性；在相对定位约束参数化中，推导了特征间一般位置约束关系的约束变换矩阵，拓宽了约束表示范围，并对约束的自由度亏损情况进行了分析。
