Point-based Surface Rendering with Motion Blur
(The Eurographics Association, 2004)
In this paper we show how to extend point-based surface rendering to illustrate object motion. We do this by first extruding the circular points into ellipsoids, which fill the space traced out by the points in motion. ...
Interactive 3D Painting on Point-Sampled Objects
(The Eurographics Association, 2004)
We present a novel painting system for 3D objects. In order to overcome parameterization problems of existing applications, we propose a unified sample-based approach to represent geometry and appearance of the 3D object ...
Multi-Resolution Sound Rendering
(The Eurographics Association, 2004)
Point-based multi-resolution representations have been used successfully for rendering highly complex three dimensional scenes in real-time. In this paper, we apply this paradigm to sound rendering: A hierarchy of stochastic ...
Topological estimation using witness complexes
(The Eurographics Association, 2004)
This paper tackles the problem of computing topological invariants of geometric objects in a robust manner, using only point cloud data sampled from the object. It is now widely recognised that this kind of topological ...
Post-processing of Scanned 3D Surface Data
(The Eurographics Association, 2004)
3D shape acquisition has become a major tool for creating digital 3D surface data in a variety of application elds. Despite the steady increase in accuracy, most available scanning techniques cause severe scanning artifacts ...
Progressive Compression of Point-Sampled Models
(The Eurographics Association, 2004)
decomposition of the point set and thus easily allows for progressive decoding. Our method is generic in the sense that it can handle arbitrary point attributes using attribute-specific coding operations. Furthermore, no ...
A Barcode Shape Descriptor for Curve Point Cloud Data
(The Eurographics Association, 2004)
In this paper, we present a complete computational pipeline for extracting a compact shape descriptor for curve point cloud data. Our shape descriptor, called a barcode, is based on a blend of techniques from differential ...
Shape Segmentation and Matching from Noisy Point Clouds
(The Eurographics Association, 2004)
We present the implementation results of a shape segmentation technique and an associated shape matching method whose input is a point sample from the shape. The sample is allowed to be noisy in the sense that they may ...
Meshing Point Clouds Using Spherical Parameterization
(The Eurographics Association, 2004)
We present a simple method for meshing a 3D point cloud to a manifold genus-0 mesh. Our approach is based on recent methods for spherical embedding of planar graphs, where we use instead a k-nearest neighborhood graph of ...
Compression of Point-Based 3D Models by Shape-Adaptive Wavelet Coding of Multi-Height Fields
(The Eurographics Association, 2004)
In order to efficiently archive and transmit large 3D models, lossy and lossless compression methods are needed. We propose a compression scheme for coordinate data of point-based 3D models of surfaces. A point-based model ...
