3D Organic Modeling Using Hybrid Techniques with Polygons

2019
This work presents a methodology of 3D modeling suitable for the design and manufacture of components with complex forms of organic inspiration. It is applied to a real case of development of a sculptural element related to the corporate image of a company.

Draw and cut: intuitive 3D osteotomy planning on polygonal bone models

International Congress Series, 2003
Abstract We present a novel approach on computer-assisted 3D planning of arbitrarily shaped osteotomies on polygonal bone models. Osteotomy lines can be drawn ‘free-hand’ onto a 3D geometry, either by stroke projection or by the use of several control points, that are automatically connected in a shortest way, approximating osteotomy lines across a ...

A Web-based retrieval system for 3D polygonal models

Proceedings Joint 9th IFSA World Congress and 20th NAFIPS International Conference (Cat. No. 01TH8569), 2002
This paper describes a Web-based retrieval system for 3D polygonal models. Feature descriptors of 3D polygonal model are reduced by feature descriptor grouping techniques. This enables fast queries of 3D polygonal models from the databases. Also, the system can retrieve colors from material color databases for 3D polygonal models reflecting users ...

Towards a genetic algorithms approach to designing 3D polygonal tree models

Proceedings of the 2002 Congress on Evolutionary Computation. CEC'02 (Cat. No.02TH8600), 2003
The OpenGL graphics libraries (http://www.opengl.org) provide a powerful environment for programming three-dimensional virtual worlds, and are used in a wide variety of applications. However, the creation of individual 3D models to include within a virtual world is an arduous and time-consuming process.

Automatic reconstruction of polygonal room models from 3D point clouds

2013 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2013
The implementation of context-bound tasks at a higher level of abstraction often demands a semantic representation of the environment and the enclosed objects. A fundamental step towards the creation of rich semantic models is the abstraction of information from the raw and oftentimes unordered sensor data. In this work, we introduce a novel method for

Automatic Generation of 3D Building Models from Complicated Building Polygons

Journal of Computing in Civil Engineering, 2013
AbstractA three-dimensional (3D) urban model is an important information infrastructure that can be utilized in several fields, such as urban planning and game industries. However, enormous time and effort have to be spent to create 3D urban models using 3D modeling software.

Semi‐Automatic Conversion of 3D Shape into Flat‐Foldable Polygonal Model

Computer Graphics Forum, 2017
AbstractThis paper presents a method that can convert a given 3D mesh into a flat‐foldable model consisting of rigid panels. A previous work proposed a method to assist manual design of a single component of such flat‐foldable model, consisting of vertically‐connected side panels as well as horizontal top and bottom panels.

Polygon topology generation algorithm research based on 3d modeling

2011 IEEE 2nd International Conference on Software Engineering and Service Science, 2011
Arrange topological sequence of building surface feature vertex is a significant research field in 3d modeling field. We can get the wire frame model of building by arrange the topological sequence and do some related operation. But there is also lack of an algorithm that quick and suitable for established all of the polygon topological sequence.

Digital Watermarking for 3D Polygonal Model Based on Wavelet Transform

Volume 2: 19th Computers and Information in Engineering Conference, 1999
Abstract Recently, much interest is being taken in a method to protect the copyright of digital data and prevent illegal duplication of it. However, in the area of CAD/CAM and CG, there are no effective ways to protect the copyright of the 3D geometric models.

Affine Invariant Watermarks for 3D Polygonal and NURBS Based Models

2000
We present a scheme for embedding secret or public readable watermarks into 3D models consisting of polygonal or NURBS surfaces. The scheme realizes affine invariant watermarks by displacing vertices (control points) and satisfies constraints regarding maximum tolerated vertex movements or, in the NURBS case, differences of original and watermarked ...
