CAREER: Haptic Models of Large Structures

职业生涯：大型结构触觉模型博齐达尔·斯托亚季诺维奇(Bozidar Stojadinovic)``我听说了，但我忘了。我看到了，我记得。我知道，我也理解。老子，604-531BCT这个职业项目的目标是做一个触觉结构建模的工具。这个工具将是一个虚拟的环境。用户将能够看到并飞越一个巨大的结构。使用者还将能够触摸该结构，感受其阻力，并将其涂抹在其上。为此，我打算将触觉界面工具整合到增强现实环境中。我未来四年的目标是：1.使用VRML创建一个用于三维框架结构建模的虚拟环境，并将其与土木结构结构分析程序DRAIN-3DX接口。将触觉界面融入到这个虚拟环境中，开发了一种针对大型结构的触觉渲染方法，使用户能够推动结构并感受其变形。虚拟建模环境和真实实验室环境的接口，使通过同一接口处理虚拟和真实的子结构成为可能。开发触觉结构建模工具是一个挑战，大型物体的触觉绘制是一个悬而未决的问题。虚拟和真实子结构的非触觉接口的设计以前从未完成过，但对于地震工程模拟网络(NEES)来说可能具有更广泛的意义，NEES是美国国家科学基金会于1999年启动的一个为期五年的倡议。挑战在这里，但拥有一个触觉学习工具的好处是巨大的！学生们将能够触摸建筑物，抵抗山体滑坡，感受地震振动，并沉浸在流体中。这个触觉工具将需要从听觉和视觉到触觉和行动的学习。和理解，因为老子的意思是两千五百多年前。

CAREER: Haptic Models of Large Structures Bozidar Stojadinovic ``I hear and I forget. I see and I remember. I do and I understand.'' Lao Tsu, 604-531 BCThe goal of this CAREER project is to make a tool for hapticstructural modeling. This tool will be a virtual environment. A userwill be able to see and fly through a large structure. The user will,also, be able to touch the structure, to feel its resistance, and topush on it. To do this, I intend to merge a haptic interface tool intoan augmented reality setting.My objectives for the next four years are:1. To make a virtual environment for modeling three-dimensionalframe structures using VRML and interface it to DRAIN-3DX, aprogram for structural analysis of civil structures.2. To incorporate a haptic interface in this virtual environmentand develop a haptic rendering methodology for large structure,enabling the user to push the structure and feel its deformation.3. To interface the virtual modeling environment and thereal laboratory environment by making it possible to addressvirtual and real sub-structures through the same interface. Development of a haptic structural modeling tool is a challenge.Haptic rendering of large objects is an open problem. Design of ahaptic interface to virtual and real substructures has not been donebefore, but may have a broader significance for a Network forEarthquake Engineering Simulation (NEES), a five-year NSF initiativetaking off in 1999.The challenges are here, but the benefits of having a haptic learningtool are huge! Students will be able to touch structures, resist landslides, feel earthquake vibrations and immerse in fluid flow. Thishaptic tool will take learning from hearing and seeing to touching anddoing... and understanding, as Lao Tsu meant two-and-a-half milleniaago.--
