This paper describes the 3D GIS research efforts done by the GIS research groups as well as by major GIS software vendors world wide, namely Environmental System Research Institute (ESRI) Inc., ERDAS Inc., Integraph Inc., and PCI Geomatics Inc. Research works done by the authors of this paper formed major discussion of this paper including a discussion on why the 3D GIS software is difficult to...

The combination of scanning electron microscopy for high spatial resolution, images from multiple angles to provide 3D information, and commercially available stereo photogrammetry software for 3D reconstruction offers promise for nanometer-scale dimensional metrology in 3D. A method is described to test 3D photogrammetry software by the use of virtual samples-mathematical samples from which si...

Introduction: Neurovascular lesions may cause death or disability. Some of them are operable, but surgical approaches to these lesions are complicated and proper access is crucial. A few numbers of these surgeries occur in every resident education period and their experience for operating these lesions may be quite inadequate. Using new technologies like 3D-restructure of vascular lesion images...

This paper examines procedural modeling as a tool for 3D modeling creation. Procedural modeling historically has been used for 3D visualization of natural features, but with the release of the software CityEngine in 2008, the technology can easily be adopted also in problem domains dealing with urban environments. Then, we will examine and compare two types of modeling, traditional and proc...

Recent development in 3D printing technology has opened an exciting possibility for manufacturing 3D devices on one's desktop. We used 3D modeling programs to design 3D models of a tissue-handling system and these models were "printed" in a stereolithography (SLA) 3D printer to create precision histology devices that are particularly useful to handle multiple samples with small dimensions in pa...

QSPR modelling is a very useful and popular methodology for estimating the physical and chemical properties of molecules. The inputs for QSPR models are 3D structures of molecules. Currently, the 3D structures for millions of molecules are publicly available. A large number of these 3D structures were generated by software tools for the conversion of 2D structures into 3D. Moreover, the generat...

Range and vision sensors are used to capture virtual reality models of a robot cell, its manipulation objects and environment. The captured models are used to develop and test user programs for the cell without using the cell itself. Finally, the user programs are downloaded into the cell and veriied. INTRODUCTION As virtual reality (VR) systems improve in performance attention is turning towar...

Graph drawing software are now commonly used. However, the choice of a well-adapted program may be hard for an inexperienced user. This poster presents a website (http://www.polytech.univ-nantes. fr/GVSR/) built to help users choose a program adapted to their problems. So far, this site uniformely presents fifty programs and aims at helping users both in their choices and in comparing the progr...
