Rapid Geometric Modeling for Unstructured Construction Workspaces

COMPUTER-AIDED CIVIL AND INFRASTRUCTURE ENGINEERING, Issue 4 2003
Yong-Kwon Cho
Most automated and semi-automated construction tasks require real-time information about the local workspace in the form of 3D geometric models. This article describes and demonstrates a new rapid, local area, geometric data extraction and 3D visualization method for unstructured construction workspaces that combines human perception, simple sensors, and descriptive CAD models. The rapid approach will be useful in construction to optimize automated equipment tasks and to significantly improve safety and a remote operator's spatial perception of the workspace. [source]

Generation of a virtual reality-based automotive driving training system for CAD education

COMPUTER APPLICATIONS IN ENGINEERING EDUCATION, Issue 2 2009
Janus Liang
Abstract Designing and constructing a virtual reality-based system is useful for educating students about scenario planning, geometric modeling and computer graphics. In particular, students are exposed to the practical issues surrounding topics such as geometric modeling, rendering, collision detection, model animation and graphical design. Meanwhile, building an application system provides students exposure to the real-world side of software engineering that they are typically shielded from in the traditional computer class. This study is a description of the experiences with instructing "Computer-aided Industrial design" and "OOP," two introductory classes that focus on designing and generating the VR based system possible in the course of a semester and then "VR System," an advanced course in the next semester. This study emphasizes the continuing evolution in the training and educational needs of students of CAD-systems. This study breaks down an automobile driving training system into different components that are suitable for individual student projects and discusses the use of modern graphical design tools such as 3ds MAX for artistic design in this system. The conclusion of this study proposes a rough schedule for developing a VR based system during the course of a semester and an overview is given of a concept of a virtual reality-based design and constructing system that is being developed. © 2008 Wiley Periodicals, Inc.

Differential Representations for Mesh Processing

COMPUTER GRAPHICS FORUM, Issue 4 2006
Olga Sorkine
Abstract Surface representation and processing is one of the key topics in computer graphics and geometric modeling, since it greatly affects the range of possible applications. In this paper we will present recent advances in geometry processing that are related to the Laplacian processing framework and differential representations. This framework is based on linear operators defined on polygonal meshes, and furnishes a variety of processing applications, such as shape approximation and compact representation, mesh editing, watermarking and morphing. The core of the framework is the definition of differential coordinates and new bases for efficient mesh geometry representation, based on the mesh Laplacian operator. [source]
