Towards a genetic algorithms approach to designing 3D polygonal tree models
Proceedings of the 2002 Congress on Evolutionary Computation. CEC'02 (Cat. No.02TH8600), 2003The 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), 2013The 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, 2013AbstractA 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, 2017AbstractThis 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, 2011Arrange 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, 1999Abstract 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
2000We 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 ...

An adaptive steganographic algorithm for 3D polygonal models using vertex decimation
Multimedia Tools and Applications, 2012Most 3D steganographic algorithms emphasize high data capacity, low distortion, and correct data extraction. However, their disadvantage is in the existence of the same embedding capacity for each data-embedded vertex in the 3D models. Embedding the same capacity in the vertex located on the surface with different properties may cause obvious ...

Snake-Based Boundary Search for Segmentation of 3D Polygonal Model
2019Many existing 3D model segmentation methods require user input to accurately segment the virtual models. This paper applies snake-based (or contour) approach to automatically search for the boundary between the two connected functional features. The search is guided by the skeleton model. The proposed approach courageously modifies the geometric meshes
