This method represents the virtual objects in Euclidean space instead of in affine space, which is consistent with the popular graphics rendering tools such as OpenGL and is more common in practice. A new classification based local and global tracking strategy to match features between the reference image and the currently frame directly is presented, which enables the augmented reality system working effectively even under large changes of viewing angles. A novel affine coordinate system definition method based on a collection of feature points is also proposed, which makes the tracking method effective even when not all the reference points are detected during the whole process, as long as there are at least four pairs of reference points correspondences.

该方法以仿射变换为桥梁来建立欧氏空间下的摄像机坐标系与世界坐标系之间的变换关系，它与OpenGL等当前流行的图形渲染工具一致，具有更强的通用性；采用基于分类的自然特征匹配策略，能够在视角和视点发生大幅度变化情况下依然正常工作；提出基于特征点集合的仿射坐标系定义方法，使增强现实系统在最小配置下只需4点追踪成功即可完成注册，比需要6点的透视投影方法具有更好的健壮性和精确性。

The aftertreatment program is developed using OpenGL technology, and it can vividly display the temperature field and the microstructure field during the quenching process.

后处理程序中采用OpenGL技术，用图形的方式形象、直观地显示出工件在淬火热处理过程中任意时刻温度场和组织场。

Linear Algebra is mainly a subject which studies the linear structure of finite dimensional linear space and its linear transformation while linear concept is in itself from the old Euclid Geometry. The concept of "Linear Space" is a kind of algebraic abstract. In many fields of modern engineering project and technology, because of the influence of computer and graph showing, the algebraic disposal of geometric questions, the visual disposal of algebraic questions, algebra and geometry are tightly combined.

线性代数主要是研究有限维线性空间及其线性变换这一代数结构的学科，而线性概念究其根源则是来自古老的Euclid几何，线性空间概念是几何空间的一种代数抽象，在现代工程技术的许多领域里，由于计算机及图形显示的强大威力，几何问题的代数化处理，代数问题的可视化处理，把代数与几何更加紧密地结合在一起。

The "Basic" part refers to the BASIC (Beginners All-Purpose Symbolic Instruction Code) language,a language used by more programmers than any other language,Visual Basic has evolved from the original BASIC language,Now it contains several hundred statements,functions,and keywords,many of which relate directly to the Windows GUI,Beginners can create useful applications by learning just a few of the keywords,yet the power of the language allows professionals to accomplish anything that can be accomplished using any other Windows programming language.

Basic是指BASIC语言，这种语言的使用比其他任何语言都多。Visual Basic源于原来的Basic语言，现在已经有好几百条语句、函数、关键词，其中好多都是直接与Windows的图形用户界面有关。初学者通过学习少量的关键词就能创建有用的应用程序，而该语言的强大功能可以让专业人员实现任何用其他Windows编程语言所实现的功能。
