3D Topological modeling and visualisation for 3D GIS

Computers & Graphics, 1999
Abstract Beyond Virtual Reality, 3D Geographical Information Systems should provide efficient spatial analysis tools able to use all capabilities of the third dimension, and a visualization that could operate on the results of queries. To address these issues, this paper presents a fully 3D topological model that was implemented in an object-oriented

Classification of 3D models for the 3D animation environments

2009 IEEE International Conference on Systems, Man and Cybernetics, 2009
Classification the 3D models in the graphical environment is a key problem with applications in computer graphics, virtual reality, especially the intelligent virtual human for Humanoid Animation. The challenging aspects of this problem are to find a suitable shapes' feature that can be used to compare them quickly and a proper method to classify the ...

3D Sketch-Based 3D Model Retrieval

Proceedings of the 5th ACM on International Conference on Multimedia Retrieval, 2015
How to draw 3D sketches in a three-dimensional space and how to use a hand-drawn 3D sketch to search similar 3D models are brand new and challenging research topics. In this paper, we make an initial study on 3D sketching and propose a novel 3D sketch-based 3D model retrieval system. Our system allows users to freely draw 3D sketches in the air as well

Interaction with constraints in 3D modeling

Proceedings of the first ACM symposium on Solid modeling foundations and CAD/CAM applications - SMA '91, 1991
This paper presents an implementation of an interactive solid modeling system that integrates 1) the definition of objects by graphical interaction and 2) the specification of objects by geometric constraints. In this system, interactive modeling operations for constructing assemblies automatically generate constraints to maintain the properties ...

3D warp brush modeling

Computers & Graphics, 2006
We introduce 3D warp brush, a new method for interactive shape modeling in an immersive virtual reality environment. 3D warp brushes are implicitly defined tools that operate on triangle meshes. We combine the efficiency of explicit mesh representations with intuitive implicit modeling operators.

Interactive 3D Model Completion

9th Biennial Conference of the Australian Pattern Recognition Society on Digital Image Computing Techniques and Applications (DICTA 2007), 2007
A common problem when using automated structure from motion techniques is that the object to be modelled can only be partially reconstructed from the video. This can occur because not all of the object is visible in the video, or because of featureless or ambiguous regions on the object's surface.

3D-Copies of Surface-Reconstructed 3D-Models

1991
An automated surface-reconstruction procedure to build 3D-copies of 3D-objects has been developed. The 3D-reconstruction is derived from several adjacent Magnetic Resonance Imaging (MRI) slices where the object outer boundaries are first detected, thinned and finally vectorized using Freeman chain-encoding techniques.

3D Model to 3D Print

2010
It’s time to bring the ideas you’ve learned in the first couple of chapters and develop a model in SketchUp for 3D printing in Shapeways. The goal of this chapter is to get you acquainted with all the basic steps of developing a model for 3D printing.

3D DATA PROCESSING FOR 3D FACE MODELLING

2006
In this research we describe 3D data processing operations which were applied to 3D laser scans of human heads before 3D eigenfaces could be obtained both in shape space and color space. Modified median filtering was used to remove laser scan spikes. 3D scans registration exploits mapping of 3D mesh to the reference 3D mesh. The mesh is based on Facial
