Description: 要想从头开始建立一个引擎的话，我们首先得需要有良好的基础。在这一部分，我们将
介绍最新的DirectX 9.0 并且好好看一下其SDK 里提供的DirectX 示例框架。出于简化的考虑，
我们将把引擎建立在微软提供好的一些类上。除此以外，我们还将研究一下DirectX9.0 的一
部分，Direct3D 扩展库（D3DX）。这个工具库将满足我们对3D 数学库的基本需要，同时也
给我们提供了加载，维护我们游戏资源的方法。
在DirectX 9.0 中，我们也将深入地研究HLSL 语言，HLSL 语言是类似与C 语言的开
发语言，它可以使着色器程序员在不借助底层汇编渲染代码的情况下编写顶点和像素着色器。
这是介绍我们今天的图形硬件3D 着色器编程的好方法。鉴于其易用性和可读性，这本书将
集中介绍HLSL 语言的使用而非底层汇编语言。
对于那些想要学习底层汇编语言的读者，HLSL 也可以作为一种辅助的学习手段。DirectX
SDK 里的命令行式的HLSL 编译器（fxc.exe）通过使用/Fc 命令选项可以将HLSL 程序转换为汇
编语言文件。通过编写HLSL 代码和查看对应的汇编代码，读者就能够更加了解这两门语言。
将某些特定的代码改由汇编代码编写也可以大大地提高HLSL 代码的效率。-To build an engine from scratch, we must first need to have a good foundation. In this section, we will introduce the latest DirectX 9.0 and take a look at the DirectX SDK provides an example in the framework. For simplification reasons, we will provide a good engine built on Microsoft, a number of class. In addition, we will also look at part of DirectX9.0, Direct3D Extension Library (D3DX). The tool library will meet our basic needs of 3D math library, but also provides us with a load, maintenance of our game resources. In DirectX 9.0, we will study in depth HLSL language, HLSL language is similar to C language development language that allows programmers shader rendering code compiled without the aid of the underlying case of the preparation of vertex and pixel shader. This is to introduce today s graphics hardware 3D shader programming a good way. Given its ease of use and readability, this book will focus on the use of language rather than the underlying HLSL assembly language. Fo Platform: |

Description: 医学图象处理及其三维重建是目前研究的热点问题，它涉及计算机图形学、数字图像处理计算机视觉、以及人机交互技术。
医学图像预处理与三维重建是可视化技术的核心环节，二者直接关系着三维可视化的效果和速度。本文介绍了灰度变换噪声消除以及
伪彩色编码等图像预处理技术。然后着重探讨了三维重建技术中的体绘制和面绘制算法以及这两种算法的优点和不足。最后总结了网格消减算法，并利用它对MC算法进行表面网格简化。
-Medical processing and 3D reconstruction is a hot spot field, which consists of applying computer graphic theory, image
processing technique, computer vision theory and human-computer interacting technique. Pretreatment and 3D reconstruction of medical images are two vital steps in the whole visualization, effecting directly the result and speed of visualization. In this thesis, Firstly, it offers a detailed introduction about the pretreatment technique, including grey-scale transformation and noise elimination and pseudo color coding. Then aiming at the 3D reconstruction, the surface rendering algorithms and volume rendering algorithms are detail discussed. At last triangle collapse is summarized and used to simplification of medical image 3D model which is reconstructed by MC algorithms.

Description: This tool is a simplification of the ballpivoting algorithm. It imagines a bella eating a delaunay traignulation in order to extract a manifold surface.
It requires a single parameter: radius of the fretting ball.
Ball Fretting
Given a uniform sampled filled point cloud returns a tight triangulation.
Input:
■tetr: a set of tetraedrons, nx4 array. If the cloud is not tesselated yet you need to call a delaunay triangulator prior calling this function.
■p : nx3 array, 3D set of points.
■r : the only parameter of the algorithm, the radius of the fretting ball
Output:
■t : triangles ids, nx3 array
■tnorm: normals of triangles with outwards orientation Platform: |

-Mesh Simplification Viewer
This program implements four different mesh simplification algorithms. After loading a mesh, the user can easily remove triangles from the mesh and the results are displayed in real time. The mesh can also be rotated and moved closer to or farther away from the viewer.
The goal of mesh simplification is to display a 3D polygonal mesh with fewer triangles while retaining the same shape. In the example above, the original cow model (upper left) is made up of over 5800 triangles. We can easily remove thousands of triangles from this mesh and still display a very similar cow model. While the 500 triangle cow is a cruder representation, this may not make a difference if the cow is far away from the viewer.
