查询词典 virtual object

A positive and negative projection method of object to be tested based on universal pattern display card includes using 3D texture to present rebuilt body data of object to be tested, calculating out directional vector array of ray outgoing point to detectors, storing said vector array into pattern display card to form directional vector texture, rotating directional vector texture and directional vector around rotary shaft to realize once of positive projection course on any projective angle, using 3D texture index technique to let virtual slab set position be not limited any more in negative projection course.

本发明属于投影探测与成像技术领域，其特点在于该方法含有以下步骤：把被测物体的重建体数据用三维纹理存储表示；预先计算射线出射点至平面探测器上个探测器之间的方向向量数组，并存储到通用图形显示卡中形成方向向量纹理；利用方向向量纹理与方向向量绕旋转轴旋转来实现任一投影角度的正投影过程的一次完成，无中间结果转存；在反投影过程中，利用三维纹理索引技术使虚拟切片组的放置位置不再受到限制。

VTK is an object-oriented universal class library, which is widely used in science and engineering field. In this paper, the visualization pipeline of VTK is introduced, and it is discuss that principles and implemental methods of two interactive cutting. This technique could be applied to medical teaching, scientific research and clinical diagnosis where virtual cutting is needed, finished the functions of 3D reconstruction and virtual cutting, thereby satisfy requirements of clinic and research.

VTK是面向对象的通用可视化类库，在科学和工程界有着广泛的应用，文中主要介绍交互式切割的意义以及VTK的可视化开发流程，并在此基础上讨论了两种交互式切割方式(Cropping和Clipping)的原理和实现方法，提出将其应用于医学教学、科研和临床诊断的虚拟切割中的设想，完成三维重建与虚拟切割的功能，从而满足临床与科研的需要。

The virtual method table, in contrast, includes all of the object's virtual methods, both inherited and introduced.

相反，虚拟方法表包含所有对象的虚拟方法，不仅是祖先的而且有引入的。

As a kind of research to the image-based virtual reality technique, this lesson have also researched the virtual to the alone object.

作为一种基于图像的虚拟现实技术，本课题还研究了对单独实体对象的虚拟。

However, by describing virtual organization as a noun these authors reify the idea of the virtual organization as object at the same time that they define it as a corporate entity nested in a continually shifting pattern of cooperative relationships that swiftly capitalizes on opportunities for new products and services.

Dr.eye：但是，在把虚拟的组织描述为名词这些作者reify 作为对象的实际上的组织的想法同时时，当公司个体在一个连续移动的迅速为新产品和服务由于机会而获利的合作的关系的模型里造巢时，他们确定它。

When you delete a file, the service simply requires the virtual path to the file you wish to delete; I store this virtual path in a SubItem of the ListItem object when populating the ListView control, so all I do here is read that value out and send it back to the file service.

当您删除文件时，只需要服务的虚拟路径的文件要删除，我在一个商店的ListItem时填充ListView控件对象，分项目，这个虚拟路径，因此，所有我做的，是读出来的价值其发回的文件服务。

Last but not least, the paper systematizes the content of the virtual survival upon the character of two-dimension and three-dimension and further differentiates it in the dimension of object and subject, which, therefore, makes the jumble thoughts of virtual survival clearer and more understandable.

第四，根据二维和三维的特征对虚拟生存的内容进行了划分，并进一步作了主体和客体向度上的区分，这样使庞杂的虚拟生存内容变得条理化和清晰化。

Position tracker is one of the most critical input devices for human-machine interface utilities in virtual reality and other human-machine interaction systems.It determines the position and orientation of an object of interest (such as the user's head) and passes the information to the host computer in real time,which redraws the virtual world on the basis of the current visual point of the user.

位置跟踪器是虚拟现实和其它人机实时交互系统中最重要的输入设备之一，它实时地测量用户身体或其局部的位置和方向并作为用户的输入信息传递给虚拟现实系统的主控计算机，从而根据用户当前的视点信息刷新虚拟场景的显示。

VI The interface between multi-body simulation system and I-DEAS is developed, and the visual simulation of self-propelled gun is fulfilled based on the I-DEAS platform. Multi-media shows of self-propelled gun are accomplished including curve simulation, texturing, lighting technology voice effect, flame effect, etc. VII Distributed real-time dynamics simulation system for virtual self-propelled gun, which is a solid basis for virtual-reality gun, is set up through LAN, based on TCP/IP protocol, OpenGL, Client/Server, Object Oriented, etc.

在3D MAX开发环境中，利用纹理、光照等技术进行了自行火炮的真实感建模，通过曲线拟合，模拟火炮各个部件在发射过程中的运动规律，并结合声音和炮口火焰效果，实现了自行火炮发射动力学的多媒体描述。7、基于TCP／IP协议、OpenGL、Client／Server、面向对象等技术，在LAN平台上建立了火炮发射动力学分布式实时仿真系统，为研究虚拟火炮打下了坚实基础。
