CAREER: Haptic Models of Large Structures

职业：大型结构的触觉模型Bozidar Stojadinovic“我听说过，但我忘记了。我看见了，我记得。我知道，我也理解。“Lao Tsu, 604-531 bc”这个CAREER项目的目标是制作一个触觉结构建模工具。这个工具将是一个虚拟环境。用户将能够看到并飞过一个大型结构。用户也将能够触摸结构，感受其阻力，并推动它。为了做到这一点，我打算将一个触觉界面工具合并到增强现实环境中。我未来四年的目标是：1。利用VRML构建三维框架结构建模的虚拟环境，并将其与土木结构分析软件DRAIN-3DX相连接。2 .在虚拟环境中加入触觉界面，开发大型结构的触觉渲染方法，使用户能够推动结构并感受到其变形。实现虚拟建模环境和真实实验室环境的接口，使虚拟和真实的子结构可以通过同一接口进行处理。触觉结构建模工具的开发是一个挑战。大型物体的触觉渲染是一个开放的问题。虚拟和真实子结构的触觉接口设计以前还没有做过，但对于网络地震工程模拟（NEES）可能具有更广泛的意义，NEES是1999年启动的一项为期五年的NSF计划。挑战就在这里，但拥有触觉学习工具的好处是巨大的！学生们将能够触摸建筑物、抵抗滑坡、感受地震振动和沉浸在流体流动中。这个触觉工具将学习从听和看到触摸和做…二千五百年前老祖所说的理解

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.--
