This paper provides an overview of the development of 3d modelling software and discusses the most popular techniques used in commercial projects today. The aim of this paper is to provide a student of 3d design with a background of historical knowledge of the development of 3d modelling programs and computer graphics and elaborates on the groundbreaking work carried out by some of the foremost...

Sketch-based applications are rapidly gaining popularity in 3D modelling because of the intuitive penand-paper metaphor. Even inexperienced users with little computer graphics and digital design background can use them to create 3D models rapidly. However, the development of sketch-based applications is usually difficult and time consuming. In this paper, we present a framework for simplifying ...

Recently, laser scanning has been receiving greater attention as a useful tool for real-time 3D data acquisition, and various applications such as city modelling, DTM generation and 3D modelling of cultural heritage sites have been proposed. However, robust filtering systems for distinguishing onand off-terrain points from 3D point-cloud data collected by an airborne laser scanner still have ma...

Three-dimensional (3D) point cloud models of trees were developed using the software packages Maya and MATLAB. These models are to be assembled into a forest scene that can be used for producing simulated Laser Detection and Ranging (LADAR) imagery of objects obscured beneath the canopy. This document describes the approach for modelling the trees using Maya then importing and completely recons...

This paper presents a 3D reality modelling system, applying lasers and digital photography to create superaccurate photo-realistic three-dimensional worlds. A key feature of the 3D reality system is its flexibility. It can be used with all common long-range scanners and digital or video cameras, without the need of any pre-calibration or static arrangement between the different sensors. The sys...

The use of 3D tracking systems in a Virtual Reality environment may definitely change CAD interfaces and free-form surface modelling. In this paper an original method for full 3D interactive surface shaping and modifying is described. VISM (Virtual Integrated Surface Modeller) has been developed with the leading idea that 3D tracking system can dramatically speed up modelling sessions. On the o...

A comprehensive benchmarking study has been carried out to determine the influence of mesh formulation and chip separation methods on reliability accuracy finite element modelling large diameter drilling operations. The Coupled Eulerian–Lagrangian updated-Lagrangian (with deletion) formulations available in ABAQUS/Explicit, together with re-meshing) DEFORM 3D are compared by simulating through-...

In this work, an automated approach for 3D building roof modelling is presented. The method consists of two main parts, namely roof detection and 3D geometric modelling. For the detection, a combined approach of four methods achieved the best results, using slope-based DSM filtering as well as classification of multispectral images, elevation data and vertical LiDAR point density. In the evalua...

In this paper an approach for 3D building modelling based on laser scanning data combined with spectral information is presented. Airborne laser scanners offer a new efficient method for 3D data acquisition (DEMs) in urban environment. However, for automatic building recognition and reconstruction, other 3D objects like vegetation or vehicles have to be excluded from the acquired DEM. Therefore...

Recently, a laser scanner has been receiving more attention as a useful tool for real-time 3D data acquisition, and various applications such as city modelling, DTM generation and 3D modelling of cultural heritage were proposed. However, robust filtering for distinguish onand off-terrain points from point cloud 3D data collected by airborne laser scanner is still issues. In particular, filterin...
